"Better Quality than factory originals, a little tight to get in the gun (Glock 22), but 31 rounds? I can't beat it. I will buy more."

"I am a firm believer in buy (quality) once, cry once. However, I bought one of these non-factory mags to see how reliable it would be for $14.95. I couldn't load more than 10 rounds without the follower tilting and jamming. The spring sounds noisier than my factory Glock mags and the fit and finish are not even close to Glock quality. What a waste of money. I would send them back, but not worth the shipping."

"I bought just one to see how it would work out. There were no jams. It fed all the rounds well. The mag was tight in the mag well, but not too tight that it would effect the action or unable to get it out. Loading was difficult after the 25th round. All I can say is what do you want for 14.95? I plan on buying a couple more."

"Ok, so I saw this item and bought it right away. A high capacity 40 cal magazine is awesome. A few notes though, on the first day out I couldn't get the mag to load properly. I was mad that I couldn't use it. What happens is the spring binds, and the rounds tilt while trying to load by hand. I gave the item 4 bullets because I know how to fix the problem, and It works absolutely flawless now."

"for the price these are some very good magazines, I was a little scared off by one of the reviews but when I loaded the magazines I did it slowly and had no problems at all......very good for the price."

"This is a great buy, I fit all thirty and unloaded it today, and too top that off i dropped it in sand! Works great but the tight fit which goes away after usage!"

"I ordered two and both are wonderful, easy and quick to load if you know how, quality seems equal on both these Glock 31 round mags. Just so you know, yes as you load them the spring will tilt, but that's normal just push the back end, and front end of the cartridge down at the same time and load each one that way. The spring has no chance to tilt. (Usually you won't get all 31 in the first time keep loading and unloading the mags will eventually stretch the springs). At this price, I would suggest you by two or three. I've never seen one locally for this price, so grab them while you can."

"Picked up two of these for my Kel-tec Sub-2000. It fit snug, no problem inserting or removing them, but they won't drop free. Even with all 31 rounds in them. It could probably be corrected with some judicious sanding. They loaded fine with a standard Glock mag-loader. in the course of 4 loading cycles apiece, had no problems with the follower tilting or spring binding as some sort."

"This magazine isn't good at all. I had a hard time loading it. The spring kept on getting stuck or something and when I un-jammed it, I couldn't put more than 26 bullets in. Then took it to the gun range to test it out my gun jammed on my 3rd shot. So I just stuck to my factory mags to finish off my bullets. I guess there is nothing better than a factory Glock magazine. I shot over 500 rounds and still no jams or problems."

"i bought this with a foregrip on my glock 3rd generation and its pretty sweet. Clicks in will not fall when mag release is pushed but i don't care."

"Mine would not even insert into the gun...but with some 150 grit then 400 sandpaper and an hour of sanding and testing it fits good...be prepared to spent time getting it to fit but quality seems good and very sturdy"

"I'm not impressed with this mag. It fits tight in the mag well and the spring and follower jam easily while loading plus I only got 30 in not 31. The quality does seem pretty good however. Who knows maybe I just got one that wasn't up to par with the rest."
1.0 5
"Unless you are ready to do a lot of filing/sanding to get the mags to fit, don't get these. Seem to be fairly good quality but are oversized and will not fit in my G23 or G27."

"CTD stop selling this item. It makes us all look bad when we buy or sell crap like this! CTD all day, but this item sucks."

"I check my e-mail while I'm at the gym to find out that my order from CTD has arrived! So, I get home and what do I find waiting for me at my back doorstep? My long awaited package from cheaper than dirt. Okay, maybe not long awaited since it only took 2 days, but still... For us shooters 2 days feels like 2 years.Anyways... I ordered this magazine for my Glock 22 and after reading some reviews I was kinda skeptical. I go straight to the toolbox and grab some sandpaper just in case. Open the box, find the mag, grab the Glock and what do you know... It slides right in! I then pull the slide back and it locks in place! I hit the mag release button and it slides out like a dream! So far, the three things that I have checked have worked which is something that we all love to see.The only downfall is this mag is REALLY hard to load. I was never a fan of loading tools and stowed the one that came with my Glock in my shooting bin. Needless to say, you will need that dang reloading tool to help ya load this monster of a mag. I havn't been able to shoot it just yet, but am planning on doing so after this crazy weekend. If this thing will not load I will put up a new update, otherwise just know that I am really enjoying the magazine.Also, as a side note, this thing looks amazing in the gun."

"Ok mag for the price. Tight fit. No drop free. Needs a little work out of the box. If you take the mag apart and shine a light inside you will notice some plastic over run here and there. This is why some people initially (including me) have feed problems. Roll up a paper towel with some 400grit sand paper and clean it out, re-oil (lightly) and you\uFFFDre off to the races!This sanding process (above) takes about ten minutes per mag.Works well in g23 and sub2k. I purchased 4 of these 6 months ago.Pay 15$ for these, and a little work, or 40 for the 22 rounders + 7-10$ for +2 plate.If you want a flawless mag out of the Box THESE ARE NOT FOR YOU.P.S. I dropped an empty mag today on a hard floor, the base plate broke. The base plate seems a bit \"brittle\" compared to stock Glocks."

"I bought this mag for my sub-2000.It was hard to load and I quit trying to get the 31st round in but it did drop free even empty. I think it will be easier to load once I use it a few times. The quality seems good and other than a sore thumb I have no complaints."

"The magazine fits snug, but it wont drop on release. It is hard to load, but with any high capacity magazine thats par. I've had two feeding problems out of 150 rounds sent through it. I like it and I am going to buy more."

"I made a large order on 1/9/2011 for multiple Cheaper than Dirt items and recieved them today 1/13/2011. My wifes first comment was \"wow that was quick\" I thought so too considering we paid for general shipping and we live in Idaho. After opening the boxes our next series of thoughts were oh, wow, and damn thats cool. I immediately checked the fit on these mags for my Cal Tech Sub 2000 40 Cal. and am really impressed they work perfectly. I also recieved some really cool things like 12 gage ALS Door Breaching rounds and ALS 12 gage stun and diversionary rounds (which I will keep for a really rainy day if you know what I mean) 30 and 50 Cal ammo boxes and numerious other items all of which were in perfect condition and were really great deals in quality and over all price. The kicker to the whole experience was that Cheaper than Dirt also included a prepaid return label just in case I was not satified with anything. I personally have not experienced service of the quality that Cheaper than Dirt has displayed very often. Buy this Mag with complete peace of mind that it is a great product with great service behind it. I plan on spending many paychecks on Cheaper than Dirt products in the future. Now I just need to get them from my wife."

"I purchased the KCI .40 Caliber 31 Round Polymer magazine for a Glock model 23, in hopes of cutting down the magazine reload time. That plan failed miserably, and it takes longer to load twenty rounds into this aftermarket magazine than it does to stuff ten rounds in two Glock mags.PROS: Can hold 31 rounds of .40 SW... in theory.CONS: You'll need a pry-bar to fit more than twenty rounds.I'm a big strong guy and work with my hands all day, yet this magazine had a spring so strong that even the first round in felt like the tenth round on a standard Glock magazine. 15 rounds in, I was concerned that I might sever a finger open on the metal liner if I slipped... I was pressing that hard. Twenty rounds is max, unless you're using tools."
5.0 5
"These mags function fine in my Sub-2000 carbine. The spring is stiff when brand new, of course, but it was fairly easy to load 30 rounds in three different mags each using an UPLULA loader. I didn't try for 31, but have no reason to suspect they wouldn't go 31."
5.0 5
"These deserve more than 3 bullets. I bought 3 of them and will buy more when they are available. Like others, I first took them apart, cleaned up the rough spots inside, put 31 rounds in using an UPLULA loader, and had no problems through 200 rounds. I am using them in a Kel-tec Sub 2000 and a Glock 22. The mag\uFFFDs fit both weapons easily and stay locked in. Good mag\uFFFDs at a VERY good price. What\uFFFDs not to like?"
4.0 5
"Good mag for the money. It was hard to get all 31 rounds into the clip. A glock easy loader is a must with this clip. I do like the fact it is constructed well and free falls out of my glock."

"Seems like a great mag for the price, but the butt plate broke on my first one while sitting loaded in my nightstand. Since they are only $20, I am purchasing the Pearce butt plate #37209 for $8 and replacing it on the one that broke and the two new ones I am ordering.I could only get (by-hand) 28 rounds in it at first, but I unloaded it and reloaded it a couple times and got up to 30. I have not seen my easy loader in years, so I did not attempt the 31st round. Still, a 30 round stick is nice!!"
1.0 5
"Bought one of these hoping that some of the others just got a bad batch. Do not buy these mags. I just finished trying to fill mine up. It says it holds 31rds. When I put the 30th round in... The bottom of the magazine shot off and the spring and all my bullets shot all over the room."
4.0 5
"I just spent the better part of an hour trying to load this mag. I finally managed to get 16 in it. But only after loading and unloading several times.Im going to leave the 16 rnds in it for a few days, then try to get more in it till I get all 31 in it. Also, a GLOCK easy loader is a must have if you plan to buy this mag.Im still glad I bought it, I just wish it were easier to load."
1.0 5
"I got two of these. Both hold about 11 rounds. I took apart and forced all 30 in one, but the sencond will only max out at 20. They jam up in the mag when firing. I don't recommend any of these. It is worth staying with the factory that only hold 15 rounds."
5.0 5
"No problems..mine even dropped free with no problems...only thing u will need a mag loader . I got to 16 by hand then it got tense ..what do u expect with a new, never loaded mag?"

"A few things: spring gets weak quickly causing the rounds to get stuck in mag tube, don't fit in 2nd gen G22 without sanding, even when sanded block trigger bar from allowing the trigger to reset, baseplates can fall off, extra plastic not trimmed off causing jams. Fixes: replace baseplate with factory Glock baseplate, work great in SUB2000. If you can't load them you are weak. I have four of these for SUB2k, they get easier to load. But not worth the money unless you have a SUB2k. KCI needs to fix this or quit making them...Pro Mag twin"

"Bought 3 mags for my new Keltec Sub 2000 rifle. Put 10 JHP in the factory Glock mag. Loaded 90 rounds, 30 each, into three of these KCI mags. Fit fine in the gun and release okay but do not drop to the ground. Have read other reviews where people had to do a little sanding or oiling to work out the kinks. Not so with me. Mine worked fine, no problems whatsoever just as they came to me. Follower is very stiff, buy an UPLULA mag loader if you don't have one, yes its a must with this mag. Anyhow put 100 rds thru the new Sub2k without a single hiccup. Very pleased with the carbine and the mags. BTWL: Cheaper Than Dirt order came very quick, had it in hand in 3 business days. So happy I just ordered 3 more of these little babies. Good deal for the money."

"This thing is junk, looks really cool. but that is all, i have a glock 23 and this mag jams about every 3 shots.I'm very dissappointed by the mag. it was my first purchase off CTD may be my last. would give a 0 if possible!"

"I bought three for the kel-tec sub2k and, they worked flawlessly. No trimming the inside plastic. They fired every shot. I only filled and fired each mag. twice so far. If I was knowingly going someplace where my life depended on that gun I would want a better mag. but for just shooting there very good. They are very hard to hand load and, I'm only loading them to twenty nine. I am not pushing them that far yet. Call me what you will but, my thumb hurt bad after loading them so, I bought a Uplula loader. That's the cat's meow and, the winning ticket with loading these mags. Never seen something work so good as the Lula loader. God Bless America! and thanks CTD."

"Bought two of these guys for my GLOCK 31 (357sig) and they worked ALMOST flawlessly only the first round chambering on the first mag jammed probably due to my own error . Excellent will buy more of these before any banning takes place. Thanks CTD"

"Tried one on my 33. Was able to get maybe 18-20 rounds before it started binding. Was able to fire all rounds with no hang-ups. Maybe needs to broken in more. Will try to load complete with Mag assist tool. I'm sure it will work fine. Buy them before there gone!"

"They worked the rounds right through my Kel Tec sub 2k and UpLula loader just as sweet as can be. Not a single glitch. I'm ordering 2 more. They hold 31rds but the little Glock-type peek holes only go to 29 - must be a +2 base on a 29 mag. Now will they hold up after thousands of rounds like a Glock factory or Scherer evidently do? I'll find out."

"Bought a few of these for my Kel-tec subk 40 cal. Just shot three mags with 28 rounds in each and they fired flawlessly. Gonna buy more. Price is right and never know when the Gov. is going to ban sales on large capacity round mags. Stock up."

"I don't think you could load 31 rounds into this mag without steel thumbs. But 22 rds works just fine. The factory Glock speedloader will only load about 15 rds before the spring get to tight. But you can't beat it for the price."

"Ordered two KCI magazines on Friday and they arrived today. The magazines are extremely stiff. I had a hard time putting in 20 with my bare hands. I used the lula speed loader, and was able to fit all 31. The magazines fired fine, I didn't have any misfeeds. They're extremely easy to place into a laptop bag, back-pack, BugoutBag, or whatever you want to call it. I suggest you buy the Uplula speed loader to max the capacity of the magazine. I'm about to order 4 more KCI magazines, you can't go wrong for the price. Hope this helps."

"Cool looking mag, had to take it apart and play with it to get to take 31 rounds. Not a bad mag for range shooting. I wouldn't use it for a life threatening situation. If you want a good high capacity mag, I know its a little more money, but get a factory glock mag."
5.0 5
"I love it. Never jams. Looks huge out of my 27. Alot of fun. Not worried about the 31, but I load 29 in it all day long by hand. Runs through ammo quickly, but I'm definitely buying more of these. I have one for my XD-9 and one for my smith and wesson 5903. Such a blast."
5.0 5
"I didnt realize it's a 31 till i came back to write this review. I got mine a few months ago and love it. Looks massive out the bottom of my 27, but gets alot of attention at the range and from friends. I load 29 in by hand all day. A little tight at the end. Wouldnt recommend to 31- don't need it any way. It def goes through ammo quickly. Will be buying a few more in the future. I have one for my XD and Smith&Wesson as well.Thanks CTD"

"I would not recommend this magazine or any of the KCI glock magazines for anything other than plinking. I have had multiple floor plate failures from KCI products. On this magazine cracked and broke with light handling with the spring shooting out the bottom and the bullets falling to the floor. When I did use this magazine, my G23 slide locked back with 10 rounds left in the mag. It kinda works, but not really worth the price or potential embarrassment of dumping your ammo on the ground at the range."

"Just got one this week, haven't shot it yet, but I noticed that after just 10 rounds (out of 31) it is hard as hell. Lookin' forward to taking it to the range, though. Will post back after shooting it."

"I bought this knowing it might not be great at first. BUT right out of the gate it was crap. It took me a long time to get it to load all 31 rounds. Then when I went and shot it, it jammed practically every round or two. Never got more then 2 rounds off be for failure to feed happened. But it makes a good paperweight on my desk."

"Buy the Glock mags. This has a few extra slots, but it will jam every time. I got two and both jam after 5-7 rounds. I have worked the springs and done everything I can think of. They're crap."

"It is ok. I got 17 rounds put in the mag before I blew the bottom out of it and broke my speed loader doing so. So what I did was take the 2 round extension off of it and out it on my normal mag to give me a couple more and I put the original plate on it. So now my 13rd mag holds 15 and the \"31\" holds 17. Its ok for the price."

"I bought two; one fits 31 rounds, and the other fits 28. Very hard to load by hand after 18, but a speed loader does the trick. You shouldn't have issues; just be careful. Getting to the max, I noticed my 28 round mag's base plate started coming off when forcing 29 in it. Other than that, GO FOR IT!"

"I decided to give this a try. YOU NEED a speed loader, as placing the rounds in the mag is really hard. I was able to get ALL 31 rounds in the mag. Went to the range and had no problems at all! Even with a fully loaded mag, it isn't that heavy. I used the Glock 27. With 31 rounds, it's about as heavy as my XD .45 fully loaded. Plus having this many rounds in the mag, means less time to change mags and reload while shooting."

"I thought this would be nice to have for my Glock 22 .40 cal. Got the mags in and they looked good. Tried to load rounds into them, and that's where the crap part begins. First mag broke, threw it away. Got six rounds into the second mag and needed the INCREDIBLE HULK's help. I wasted $$ on this crap. PS. My father is a master gunsmith. He says these mags are crap. Take that to the bank. I will return the one that didn't break and buy some MREs. At lease I'll know what to expect when I get them."

"This is a great product. The mag springs are very rigid, but that's a good thing! I was able to load all 31 rounds the day I received the extended mags. I purchased two and I'm very glad I did. I have a Glock 27 and it slams in perfectly and performs flawlessly. Great addition to any Glock!"

"I bought 3 of these mags. I am gonna now see if I can return them. They are garbage. There were no negative reviews that I remember seeing about these before buying them. Now I see every one says that they can't get more than 15 or so rounds in them and I had the same experience with them as well, even with a speed loader. The Glock speed loader does not even work properly on these. One method I found in order to get the mag full is to tap the bottom kinda hard in your hand after inserting every round, but then they feed like crap anyway. The floor plate was loose on one also. Worth every penny to just get the Glock hi cap mag."

"I got it today and discovered the spring is too long for the magazine. After the 16th round, it binds up. Started cutting one loop at a time until I could load all 31 rounds into the magazine. I'm glad I have a speed loader."

"I got one of these mags when I bought my Glock 22 off of a friend and it was still new. I was only able to hand load about the first 15 rounds. Then to finish loading it, I had to use an UpLULA universal mag loader to get the rest of the rounds in it. Though it says it's only a 31 round mag, I was able to get 32 rounds in it. I love this mag! It looks ridiculously awesome in my Glock and on my hip. Happy I was able to find another one for a price that can't be beat."

"Bought two of these mags, thinking it would be neat for my JR Carbine, but could not load past 15 rounds with fingers, then I got a loader and only could put a few more rounds in. This is a cheaply made mag. Spend the extra money and get a good one."

"Was really excited to receive this and send 30+ rounds flying without reloading. Never got more than 9 rounds loaded in it. Even the rounds I got in there didn't sit correctly. Popping them out with my finger made it VERY clear that there would have been feeding problems. Took it apart to see if I could do anything about it, but it wouldn't even go back together very easily. After struggling to get the cap back on the bottom, I couldn't believe it didn't blow off while attempting to load it. Pretty bummed about it, thought it was cool. Complete junk. People giving it good reviews are probably used to junk. As a shooter, there is no way in hell I would ever want one of these in my gun with my life on the line. Buy official Glock factory mags."

"I wasn't too sure about buying this after reading the reviews. After debate, I bought one mag for my Glock 27. It fit perfectly, and I was able to load 31 rounds. You need a mag loader. I tried to load by hand, but about round number six, the spring is so tight, it's unbelievable! But with a speed loader, it was easy! The weight isn't bad. Great to have at the range. I'm planning to buy another one again. If you're looking for a mag this size, this will work for you. Just don't try to carry and conceal - just too long."

"I had been looking for an extended magazine for my G23. When I found these I figured I would order two since the price was not that bad. At first I tried loading them to full capacity by hand. Quickly I found out that it would not work. So I tried using the speed loader that came with my Glock and I was able to load it to full capacity. I also had no problems when inserting the magazine and shooting the rounds through my Glock. The magazine fit tight, it does not wobble excessively, and the rounds fed fine. If you are looking for a great extended magazine for a good price, purchase these. Just remember that you are going to need a speed loader."

"Have three of these, had problems at first. Disassemble, take a file to all the plastic over fill from molding, clear all the metal and they work like a dream. Love the idea of 124 rounds ready to go at any moment. By the way, once the plastic is filed down emptied all three mags with out a prob. Shouldn't have to do this but I guess quality is also included in that get what ya payed for thing."

"I bought 3 of these aftermarket 31 round mags for my Glocks (models 23 and 27). After trying with each mag, I was only able to get a max of 13 rounds loaded by hand into only one mag. Another I could load 11 rounds and the last mag I was only able to load 10 rounds. I have yet to be able to fully load any of the 3 mags to full capacity, even using loaders! I will say that the rounds I was able to load did feed and fire without any problems so far, but since I am not using them, I don't think it will be a problem. Now on to the GOOD NEWS - buy the OEM GLOCK mags and save yourself this headache! I bought several of the 22 round factory GLOCK mags at the same time I bought the 3 after market mags. There is absolutely NO comparison! I was able to load every Glock mag to full 22 round capacity BY HAND on the first try! I've learned my lesson. Stick with the factory Glock mags and don't make the same mistake I made. Sometimes you really do get what you pay for! By the way, I have 3 aftermarket 31 round mags for sale if anyone is interested. They're cheap!"
