"i wanted a 33 round mag for my glock 19 so i took a chance and ordered this one, overall quality is good and after firing two full mags no ftf or fte, loading is no more difficult than trying to load a brand new factory mag, i only gave it 4 bullets because non factory mags are hit or miss i guess i got lucky and for the price you can't really lose"

"Works fine in my G26, but I got it for a Kel-tec sub-2000. Whereas factory Glock hich cap mags work perfectly, this mag will not even click into place. Maybe a little dremel tooling is in order, but that should not be necessary."

"I had purchased 3 KCI 17 rd clips earlier this year and found them to work just as well as Glock factory mags so I figured I\uFFFDd try these 33 rd mags . I took them out once put about 700 rd threw them no hang up no jamming no problems at all the springs are a little tight but like most things they get easier once broken in ."

"Ordered 5 of these last week, not 1 could we get more than 17 rounds in. Possibly I got a bad batch, sent them back for 3 Factory Glock 33 rounders for my AR. If these guys above have KCI 33 rounders that work awesome. Mine were crap and the mag srpings are super soft compaired to an original."

"I got these in the mail yesterday and haven't had a chance to fire, but thought I would share what I found so far. The quality is good, they lock in place tightly and release's easily. It was a bit hard to load first mine was hard to load more than 17 rounds. Once I tapped the bottom of the mag it freed up so that I could load more. I had to do it two or three times, but it took all 33 rnds."

"These mags are a great deal, they are a little rough around the edges compared to the glock factory ones, but work just fine. The mag I received can actually hold 34 rounds, so that was an extra bonus. Great Buy!"

"I figured out the problem most people have with these mags.Upon arrival take the mag apart and use a fine sandpaper on the metal feed rails. Make them as smooth as the factory feed rails.They arrive sharp and there is a tendency for shells to catch there.I have five of these for my 17. After I smoothed them out, they have been flawless.I keep them loaded between shoots just to check their durability. No problems.Just do what I suggest and this is a great buy!"

"I bought one of these and one of the glock factory mags, they are identical in appearance, exept these don't say glock on them. I took both to the range and they both worked perfectly but these are half the price. Worth a buy."

"Bought one of these at a gun show. Loaded it the night before a day at the range. Apparently 12+ hours of tension of the spring is too much as the follower locked near the middle of the mag. Opened it up and stretched out the spring. Works alright still a few FTL FTE requiring a tap, rack, bang. Nothing I would ever trust my life with good enough I guess for the range. and the price. Overall if I want another 33rnd Mag, Ill be buying a Glock Factory mag."

"I was skeptical of these but they are worth the 20 bucks. They function pretty good. I have only ran one mags worth through my glock but as far as I can tell they're a good buy. I will buy more."

"These mags are awesome, I bought 5 of these for my glock 17. Now I have some firepower, I gave this 4 bullets because so far, I checked them all for fit, and loading. Passed all test, I haven't been to the range yet but after I am sure ill put up 5 bullets. Buy these mags they're great really. CTD you guys and girls are awesome, thank you thank you thank you......"

"All I got to say is that, yea it is a bang for the buck, but it has weak springs. I just recently went to the shooting range and out of 10, I give its overall performance a 3. 2 Bullets for this."

"I ordered 3, shipped very fast, and recieved fast as always. I can fit 34 in each mag. Not as smooth loading as factory, but I unloaded all three mags in less than five minutes with a couple of hangers on one of the mags, but the other 2 blasted right all 33 shots fast although they will fit 34!! I may take advice of some and polish inside with emery cloth they all click in and drop free."

"For the money these things are great. I bought two, One I had no problem getting it loaded to 33. Second one it kept stopping at 17. So I got out my speed loader, and didnt have any trouble after that. At the range I didnt have any trouble either as I shot 150 rounds between the two. Great for fun. Good to go!!"

"I recently thought I'd give one of these Korean 33 rounders a try, and I'm glad I did. The main difference I've noticed with these Korean mags (much like the standard size ones) is that after molding the polymer around the metal frame, they did a poor job of trimming up the excess. This can cause the magazine to bind. I literally took about 5-10 minutes when I first got it, loaded, and unloaded the mag a couple of times and trimmed up the plastic around the feed lips. They have worked like a champ since."
3.0 5
"You can't beat the price so I bought two. I had trouble getting in the rounds, with the help of a speed loader and working the spring I got all 33 rounds in. Once at the range however I started to have malfunctions when I had six rounds left. I only shot the magazines once, so I can't say that will happen EVERYTIME but they worked. Good for practice. Someone did mention that I could replace the spring with a factory Glock spring and it should solve the problem, lets just see how much those are to see if it's worth the trouble."
5.0 5
"I actually had to use a thumb saver to get the 33rd round in the mag, but other than that, it functioned flawlessly. Other than the stamp on the bottom, you'd never know that it was aftermarket. I will be purchasing more."

"I had ordered a different brand from a place other than CTD and when it came the spring was so weak it would only feed 10 rounds at a time and not feed them that well. I was very disappointed in it. I was very reluctant to give this brand a try. I seen most not all said it was good. Well I got it and to my surprise, it function perfectly. I will have to say thanks to the reviews and to CTD, Not sure how they did it but some how they got it to me in 48 hours after I placed the order, thx CTD"

"I bought 2 of these about 2 months ago, and after 5 or 6 trips to the range, and about 500 rounds, I have no complaints at all.. No ftf or jams in either my Glock 17 or my Kel-Tec 2000. Like most other reviews, they were hard to load the first couple of times, but then they loosen up and can load 33 pretty easily."

"I, like many of you, was skeptical. However, I just couldn't pass up on the price. I got mine and I, too, had trouble getting all the rounds in place. I loaded mine with 31 rounds and left it for a few days. Then I was easily able to load the other rounds. I had no FTF. All rounds went through my Glock 17 without a problem. The one reason I only gave it 4 out of 5 is because, at the top, where the bullets feed, I had a long piece of plastic hanging. I cut it off easily with my pocket knife."

"I bought this magazine and shot 30 rounds right out of my pistol. It never jammed and ran through the magazine in a few seconds."

"I bought two of these mags. I was a little aggravated when I first tried to load them because they would only hold 17 rounds. Even with a speed loader, I could not get them to hold anymore. I let them set overnight with the 17 in them, and now they will hold 35 rounds. They function smoothly with no problems. I will agree with the other reviews that they need to be inspected more closely at the factory because they do need to be trimmed at the top. However, I do plan to buy more of these."
4.0 5
"I got two of these shipped for less than the price of one factory magazine. When you get it, take the base plate off, pull everything out, trim any burrs on the follower and run a brass brush through the inside of the magazine body. 2 minutes of work is well worth the price."

"I got two of these and they function great. They had a stiff spring at first, but I got it to break in nicely. It hasn't messed up yet. I will order more of these for sure!"

"7000 rounds thru my G17, never an FTFeed, Fire, or Eject. With 25 Brown Bear rounds in this Mag, 5 feed errors. I disassembled the Mag, it has a very light weight spring and sharp metal edges inside, and untrimmed molded plastic inside. I cleaned up the inside surfaces of the Mag, and tried 20 TULAmmo rounds. 3 jammed in 10 rounds, and I unloaded the rest. Anyone want a 33 round mag?"
5.0 5
"These mags are like the factory new mags. These do say on the box 31 rounds but if you leave the mags loaded for a couple of days then it will hold 33 very tightly. These will definitely be bought again."
4.0 5
"I ordered two of these mags and two 15rd mags. They are good copys and are almost just like the factory mags. Like other reviewers said, there are extra pieces of plastic hanging off corners that may cause issues. If you sand/file/cut them off, they're fine. Sometimes it's good to even pull them apart and rub the insides/followers just to make sure there are no rough edges. One of the mags came with more excess plastic than the other. The only reason I did not give these 5 shells is due to the quality/excess plastic. I wish I could find the factory glock internals to replace the korean stuff! Then I'd have an almost factory Glock mag."
4.0 5
"I ordered one of these magazines and a Glock factory 33 rounder also. I inspected them on arrival, and if you covered up the Glock name on the factory magazine I would have a hard time telling you which is which. I almost wish I had bought 3 or 4 more of these and not the factory magazine. I took it to the range and it performed flawlessly. I loaded and shot it 5 times. I saw that some people reported difficulty loading their magazines initially. I did not have that problem. It actually holds 34 rounds. This is a great product at a great price."
4.0 5
"Excellent product for less then half the price of an OEM Glock mag. I was able to load 33 rounds with no problems and no FTF'S. I intend to purchase more of these mags in the future if they are available. The only reason I gave this product 4 bullets was like most people who purchased these mags said, was having to do a bit of trimming of plastic."

"Ordered two to run in my Kel Tec Sub 2000. I expected to have to do some plastic trimming and touch up on them after reading the reviews. To my surprise there was no need to do anything to them when they arrived. I did tear them down and inspect them, loaded them up and ran 150 rounds with no problem. I'm a deputy sheriff and these will be with me on patrol along with the Kel Tec."

"I was skeptical of these mags at first. Mostly because I paid $59.99 for a glock factory extended mag last year, and these are only $15 bucks.However, when they arrived I was shocked at how good the quality was, next to my factory mag, the only difference is this one doesn't say Glock on it.I could only get 28 rounds in at first, but after letting it sit and then shooting the 28 rounds flawlessly, no FTF, no load problems, no trimming, etc. I was then able to fit all 31 rounds in.They lock into my G19 just as any factory mag, and release just as easily. I'm buying more today!"

"Bought one of these \"American Import\" korean mags a few months ago. I finally got out to shoot, worked just fine. no jams no needing to file stuff down like others say. I plan to buy few more in this glock hicap mag scare we are having."
5.0 5
"Looked all over for reviews of these mags before buying one, the Glock factory ones are impossible to find. After loading it with around 28 rounds I let it set for an hour or 2, them slipped the last 5 rounds in it without issue. From what I'v read from the haters, they try to load and go. Let the spring compress a little first, makes it easier to load all the way, Took it out today and this mag shot FLAWLESSLY in my G17, I WILL be buying more. (It locked the slide back every time, every time)"

"I purchased two of the Korean made magazines and one factory magazine. I immediately noticed the follower and mag spring were of lesser quality than the factory magazine. And the factory mag spring has one more coil and is made from stainless steel where the KCI spring is simple carbon steel. The follower is simple plastic while the glock follower is a better grade polymer. The base floorplate is secured by the side detentions only there is no base plate insert with the round tip to click into the base floorplate locking it into place. The body and stainless steel liner of the KCI mags looked identical to the factory. I spent an additional $10.00 per mag at the Glockstore.com and replaced the follower, mag spring, and base floorplate and inserted the base insert and re-assembled the KCI magazines. Now I can't tell the three magazines apart and all three function flawlessly. Just install some factory parts and the mags are like factory mags and function just as well but for 25% the cost."

"Ok i'm writing another review and giving 5 shells this time because after a little \"break in\" period (if you will) the mags began running flawlessly...i ordered 2 15 rounders and 2 33 rounders...i had more problems with one of the 33rd mags than any other one but after shooting approx 800/1000 rounds thru all of them they seem to work 100%. we just need to see if they remain functioning this well in the future. as for now tho i give it 5 rounds. when you get the mags make sure u trim off all excess plastic. the stuff you dont get the gun will eat up and soften and round them out....def a good idea to strip them and get all rough edges out. the 2 15 rounders i got had ZERO malfunctions. great product. fast shipping. free mag pouch. reliable equiptment. LOW LOW price. my kinda gear here! just my 2 cents..."

"Bought two and just received them in the mail. On the outside they look about the same (99%) as my other Glock 33 round mags. One of the followers seems to stick some so I will need to tear it down and look for some edges to smooth out. The other functions the same as my other Glock mags. I'll update the review after the range test this Friday.One last comment: While I have not placed them on the scale, they seem a tad lighter than the Glock mags, and the exterior feels a bit rougher."

"Bought one a few weeks ago...it needed nothing. Locked back, fed well so I ordered another. This one does not lock back and needs some work. So I guess best advice would be flip a coin before buying."

"I was a bit skeptical at first considering these are Korean made, aftermarket mags. But I took the plunge and picked up 4 of them. I loaded them up the moment they arrived and let them sit for 3 days (until the weekend came around to test these guys out at my local range). They worked flawless in a Gen 4 Glock 19. I did not have to file any of the plastic off any of the 4 magazines. I definitely would pick up more in the near future, especially at this price."

"Junk junk junk! Total junk! For one thing it only holds 29 rounds, and the ones you manage to fit in there get stuck and the spring can't push the rounds up. I wouldn't even trust this thing to work on the range, let alone in an actual firefight. Skip this thing and spend the $30 on the real thing!"

"I am an FFL and bought one of these to test it out (the price is extremely reasonable even considering wholesale from ATI). I tested it out on a Gen. 4 G19. I ran over 100 rounds through this magazine without a single problem. I fired as fast as I could to attempt to trip-up the mag; however, it ran flawlessly. I only put in 27-28 rounds in this first session. A few reviews below mine complained about the inability to completely fill the mag at first, but this is not uncommon until the spring within the magazine loosens a bit. I have Glock factory 22-round mags for the .40 S&W line and the same thing occurs. One may only be able to put 19-20 rounds in it at first without a severe struggle. I have a few Glock factory 33-rounders coming in tomorrow to test out. If my opinion changes regarding the ATI mags in time or by comparison, I will supplement this review. Overall, I am very pleased with this product and recommend it."

"I had purchased two of the non-factory KCI 15 rd magazines previously and had no problem, so I decided to give this one a shot. When first trying to load it, it would not hold 33 rounds, so I left 29 in there and tried a week later. I was able to get the last 4 in there but the floor plate stuck down and the top 2 rounds just fell out of the magazine. It took a few good smacks to get the plate unstuck and to push to the top again. After getting it to the range, the second round from the magazine stovepiped. After clearing that problem, I got constant feed problems every couple of rounds. I will keep playing with it at the range, but I wouldn't trust otherwise."

"These Mags are without a dough the worse piece of junk I ever got from Cheaper Than Dirt store. They should take them off the market. They caused such a jam in my Glock I had to completely dis-assemble the gun at the range. Bullets kept turner sideways in the mag holder, trying to double feed the chamber then jam up. Don't purchase these, buy real Glock mags. I did at my range for comparison and the Glocks never jam once. I know the price is hard to pass up, thinking they will work they did not, so take my advise spend the money on the real thing, get Glock Mags."

"These things are far from reliable. I loaded my two up for the range the night before because it is fairly difficult to get the last few rounds in. They both worked perfectly when I did it like this. The next time I loaded them up for days in advance and they both had one failure to feed. The third time I had them loaded for some time and had a few jams. I don't know what their problem is but it seems like it has spring issues if loaded for longer than a day. These are unreliable, so you should pay a little bit extra for the real thing that WILL work."

"Purchased two of these a few months ago and have taken them out roughly ten times.

"I bought 2 of these a while back but just now getting around to writing a review. First time out it was impossible to get more than 3 rounds without a failure. I took them apart and did all of the trimming and filing that is talked about on here. It helped a little. Now I can run through a magazine with only about 5-8 failures instead of 10-15. My review title is no joke. I actually use these mags for practice on clearing jams. These mags have made me a tap, rack, bang pro. Still total junk as far as I'm concerned."

"Definitely a neat product. I use these mags the day I received them. They worked wonderfully I ran 300 rounds through them. I put them up for about a month took them to the range with me and ran another 300 rounds through them I noticed the second time of using them the spring was noticeably looser and I was getting a jam about every 10th round. On the third and final trip that I took these magazines I was getting a jam every other round. So if you're looking for a short term product for the price is hard to beat. Just make sure you do not store your magazines loaded they will deteriorate even faster."

"These magazines jammed repeatedly. Not sure if it's a spring thing or what, but every pull of the trigger was followed by a misfeed. Spend the extra money on the factory mags. They are well worth it."

"I bought one of these several months ago. I tend to keep ideas in mind then buy several items at once. I purchased this mag at the same time I bought some steel AK mags.I had previously bought some of the KCI 15 round mags for my Glock 19, and they were flawless (and still are after a couple of years,) so I thought this might be similar.It wasn't.The first trip out with it was great, it had no malfunctions of any kind. The second trip was the same. I had stored the magazine loaded (33 rounds fit with no issues) between the first and second trips. The third outing, where the mag had set loaded for an extended period of time, maybe two weeks, I suffered from multiple FTF malfunctions. I did not use the magazine again and left it unloaded for a month. I took it out again last weekend, and it had the same FTF malfunctions every other round.The only thing I can try now is to get an OEM spring and follower and see if that helps the magazine. If it does, I will still be into the magazine for less than half of a Glock OEM 33 rounder.I have yet to try swapping the spring and follower, but if that works, I will be satisfied with the purchase. As it is now, how the magazine comes, I am not satisfied. But I can't be too unhappy, as I knew it wasn't a factory magazine. It was just a range toy, and relatively cheap at that."

"Spring is weak, first load shot fine, 2nd load about every 3rd round FTF. Buy factory. If you just can't bring yourself to pay for the quality then at least get a factory replacement spring, they help but I would still never use this mag if my life depended on it.

"As some of the other reviews noted, the springs are weak, but they will work with some effort. Be prepared to take the mags apart and clean the insides and trim any excess plastic. I can load my high-cap factory Glock mags without a loader, but I had to use the loader for these because of the flimsy spring. I loaded and unloaded several times and finally broke-in the spring. I fired through two mags and one of the mags still gave me problems. I literally stretched the spring (just slightly) and it fired flawlessly. I gave it three stars because of all the conditioning you have to do to get these mags to work. Would I buy them again? Yes - I now know what to do with them. So for the price you can condition them or change out the spring and other parts with factory Glock). Just remember that these are NOT Glock quality."

"I fired at least a 100 rds out of this mag the first day i got it, no malfunctions. But before i fired it, i did take it apart and swap the floor plate to make it a 31 rd mag (for alittle more spring tention) and i scraped exess plastic off of it so the follower didnt stick... Bottom line, needs alittle work out of the box, but then its flawless."

"Like others have stated, this mag has lots of excess plastic from the molding process. So you must take this apart and trim the excess if you want reliable feeding. There was some plastic in the middle of the tube that I could not reach with my razor blade. I found that an 8 inch filleting knife did the trick. The spring does seem a little weak but I haven't had any feeding issues yet. It can easily be replaced with a Glock factory spring for around $5. The finish is great and it holds all 33 rounds. I would recommend this to a fellow Glock owner."

"was a little worried bc of some reviews bashing these. they worked great. no failures of any sort using steel and brass ammo. there is a little wiggle at the bottom of the grip but it still functions fine. i got 3, and all my friends with glocks who come over want one."

"Arrived in a timely fashion. Mags are pretty much like the factory mags.They hold 34 rounds, I counted them out twice.Construction seems solid with no excess plastic anywhere. Fits solidly in a G19 and Sub2000.I have yet to take them to the range, but they loaded up fully fine the first time. I unloaded and reloaded both while counting the rounds.I'll update with any concerns after getting them out to the range."
