I bought these mags 3 months ago and have fired 700+ rounds with no problems in my Gock 17. The springs are still stiff and feed fine and are not any harder to load than Glock mags. I’m kind of poor these days and don't have the spare cash I used to but these do work just fine.

I suppose there has to be one or two bad apples in every barrel, however I suspect most were written by those who have never seen or held one of these mags. I have 15 so far and WILL buy more. I haven't range-tested tested them all yet, but have had zero problems with the G17 mags I have used (in a G19 and G26).

I bought these mags not really expecting much. When I got them, they were wrapped in the brown paper wrapper, just like everyone else described. At first glance, you can't tell a difference. It was only when I really started inspecting them did I notice the differences. The bottom plate has the KCI logo on them, and the metal insert is more of a V shape, rather than rounded like the Glock factory mag. When I loaded them, I did note the fact that they were tough to load, and once loaded, it sounded like one of the rounds shook around a bit. Once I got them out on the range, they fed fine, and didn't give me any problems. Overall, I think these mags are worth the money. The cheap mag holder didn't do me any good, but it will come in handy to loan to my CCW students who don't have their own. Train hard and stay safe!

I bought 10 kci for my g17. opened up several fromthe brown paper packaging. i compaired thm with my new factory mags and they look great. put them on my scale exact same weight as factory. dis-ssembled all parts are inter-changeable. i started using these mags for compitition and THEY WORK PERFECTLY! zero failure to feeds. the springs are stiffer than the glock ones, but that is a good thing! it is tought to get the last few rounds in the mags so i used my loader. I ENDED UP BUYING 10 MOREMAGS AND 10 OF THE 33 ROUNDERS! one of the last great gun deals!

I got these in the mail the other day, I haven't gotten a chance to shoot them yet but i have been playing with them. The springs are stiff. But i cycled a bunch through my gun without any problems feeding. Quality seems good. They fit VERY snugly in my Glock 19.

lets see. I take them out of the box. I load them with cheap ammo. I cram them into my cheap s2k. I fire off 17 rounds with no problems. Maybe the problems with others is they are pushing them in backwards. I love the price and the mags.

i have so many of these mags now its kind of silly. however i purchased 2 more just for the free pouch. they fit all three of my glocks perfectly as well as being a PERFECT fit for my sub2k. dont pay any attention to the goons saying they dont fit. the fact that they are longer ensures the fit.

Fits perfect in my sub 2000 9mm. I read posts before i purchased. I figured i could machine them down to be used in my s2k. But they fit perfect and feed perfect. Am buying more today.

I first bought a batch of the g-19 KCI branded mags they are flawless & amazing in operation. I did notice a few burrs but nothing that hampered operation, only cosmetic flaws. I then bought a batch of G17 mags then a batch of G18 mags both of these were branded KHAN. These actually were a later generation than that of first batch these were beautiful mags actually looked better than factory mags. The finish on these mags was noticeably rougher by feel only, but after wiping down with clp they are smooth to the touch. These mags are branded as American Tactical, KCI & KHAN all are A+++. Don't hesitate to buy these you will not be sorry. The only downside of these mags was due to the fact I put +2 bottoms on a few and the rounds were to loose to my liking. But with a glock factory spring or wolf these will operate up to my standards with +2 bottoms. With standard bottom you will have no problem. Enjoy simply because they are not factory don't be fooled.

Well, I took the time to conduct some measurements of KCI vs genuine Glock 17 mags. Guess what? The KCI mags are a full 1.5 mm LONGER from front to back than the factory Glock 17 mags. No wonder THEY DO NOT FIT in the magwell of my Kel Tec S2K! No wonder THEY DO NOT FIT in my HKS Glock speedloader! Anyone at KCI ever heard of building things to spec? Apparently not! You guys who are giving these crap mags 4 and 5 stars are doing prospective buyers a great disservice - knock it off!

I dont care what anyone is saying, im a high volume shooter. i shoot at least two competition a week, "i love ohio!!!". I now have 40 korean mags, they all come in a brown bag like its a granola bar of some kind (lol)! I have had some issues with a handful of them, but taking them apart and cleaning them up is not a problem. what im saying is, if you cant do an oil change on your car maybe you should stay at your moms house. These mag are a great deal!!! I can buy factory mags at cost if i want because i work at a gun shop with an indoor range. They save me $$$$$ and the work great!!!!! I am not a gun SNOB, I see these people on a weekly basis and i always out shoot them. SAVE YOU SOME MONEY AND STOCK UP!!! LET THE GUN SNOBS SIT ON THE PORCH!

Just like others have said, these magazines are great EXCEPT they have a little bit of plastic on the inside of them. 3 of the 4 mags worked perfect from day 1. The other one would hang up. I followed the directions of others, opened it up and scraped off the little circles of plastic (3 on each side). Now the mag works perfectly. All 4 mags work great. I will use these for carry.

Bought 2 of these to try out in my G17. Was greatly surprised that they worked as well as factory! Full load. I used a UpLula so didn't notice the spring problem as others have mentioned. Loaded 'em up full, let 'em set for a week, went to the range and unloaded them all several times - 100+ rds - not one FTF. Bought 6 more!! For the price I paid these are good range mags and my factory backups !!!

Buy factory, these are garbage!!!

For the price they cannot be beat. Mags do need some work in order to feed properly. as the others have said, just dissasemble the mag and scrape out the excess plastic (3 dots on either side and some on the lip). i used a curved xacto knife. went to the range and they worked flawlessly (2 sets of mags). will buy many more before momma obamma bans them, you should too. might have been charged $10 more had the Koreans done it properly in the first place, but i'm satisified with the savings and a little DIY project.

Ordered two of these to supplement my four Glock 17 mags for my Kel Tec SUB2000. Unfortunately, they don't even fit into the magwell, so it's hard to analyze the rest of the mags' merits. DO NOT BUY THESE FOR THE S2K!

I own 4 Glock pistols and purchased this bargin for my model 17 to be honest because of the price. I was figuring that the mags mwould not be that great but the pouch would offset that. To my suprise the 2 mags that i purchased work fine. I load hydra-shocks in them I don't know if this makes a difference but I do not seem to have the problems that I have read some of the other people having. I may have lucked out on this purchase but I am going to buy a couple of more sets unless I run into a bad set. I have a large number of the factory mags and these 2 have worked just as well as the factory mags. It may not be a bad ideal to take these mags apart and check for excess plastic on the inside if you are having problems. With the current administration high cap mags may once again become hard to find at a reasonable price.

Both G17 Mags are absolute JUNK! Will not load more than 7 rounds without hanging up. I won't even put these in my Glock! Stick with factory!

these clips feed pretty good, i bought them with a lone wolf 34 barrell to covert a g22 i had, with the plus 2 u have a19 round mag.

I love those mags, for the price I buy two a pay check. I have had a few problems with two of the mags, i have a total of 10 mags all together,12 if you count the factory ones. The two that gave me grief was because of extra plastic on the inside of the mag. The springs in them are awesome, they have some kind of selflubricating coating on them. i just used my pocket knife and scraped the plastic out of the inside, when i put them back together i never had any more issues after that. kind of hit and miss i guess, but for that price??? I want to have 20 of them.

when i first seen these mags i was more than skeptical, so i ordered a few of them. Now i read alot of bulletins, and alot of people have turned their noses up at them. fine by me. when i started to play with them i noticed they are HARD to load, after loading i put mag in the gun and racked the slide 17times, loaded the mag back up and did it 5 more times, never missed a beat. loaded it back up and took it to work the next day, "i work at a gunshop", got to work and went to show a coworker and when i started to thumb the bullets out,it hung up with the follwer about halfway down the mag, i then poored the rest of the bullets out on the countertop. "ok?" so i took the mag apart to see what was going on. looking thur the mag body i seen a few holes in the steel lining where the plastic outer molding was not flush. i took a butterknife to a bench grinder and made a chizzle. i then smoothed out the inside of the mag by removing the excess plastic, then reassemble the mag. loaded it up and have shot, shot, shot. No hang ups, no missfeeds, no jams, fast, slow, upside down, sideways, 100% everytime, always locks the slide back after the last round. after the spring breaks in loading it is just as easy as a factory glock mag. 1700 rounds later? im ordering me a few more. GREAT VALUE, if you dont mind doing some tinkering. I have done more than put it thru the ringer.

BOUGHT THESE CAUSE OF A 2 FOR 1 AS OPPOSSED TO A GLOCK FACTORY MAG, HAVENT FIRED THEM YET BUT THEY WERE VERY HARD TO LOAD YOU CAN TELL ITS DEFINTLY NOT A GLOCK MAG, WILL POST ANOTHER REVIEW WHEN I GO SHOOT

I would most definitely not ever use these for carry. It looks exactly the same but... the bullet kind of wedges at the top metal lips while loading it never happens on the Glock Magazines. Although this happens it didn't ruin it yet. Although it's never happened while firing/cycling only loading it kind of makes me wonder. The bullet pushed in funky almost vertical while loading it several time as well, weird and I never noticed it on the Glock magazines. Spring is pretty tight although I don't know that that's a down side. Seems to work fine other than that but definitely cheaper quality. I would say it's fine for practice but would prefer to trust my life to Glock only.

These magazines aren't that great. They load to 17 rounds okay, but they load funky, and they don't feed entirely correctly. I had one mis-feed at the range. These are fine for the range, but I wouldn't use these for CCW or home defense.

The rounds tilt up in mine.. Its pretty bad.

I'm relatively new to Glock ownership but I bought a pair of these KCI 17 rd mags for my G17. I've run over 500 rounds thru the gun at the range, more than half of them with the KCI mags and haven't had a single jam or other problem. By contrast, my brand new G26 factory mag jammed on the second shot (but then went thru another 50 with no problems). The only reason I'm not giving the KCI five stars is because the spring gets really stiff at the end, making that 17th round a bit of a push to get in. But it goes in (and comes out when it should).

I shoot a Glock model 31 (.357sig full frame) and have started using a Lone wolf match grade barrel in 9mm and two G17 magazines by Glock I purchases here at Cheaper Than Dirt that I love to use in the G31, they work fantastic. This also gives me ability to use reloaded amunition in 9mm. I later ordered these Not Factory Glock magazines due to the claim of flawless operation and a double mag pouch at 29.95, a great deal I thought. I truly regret this purchase. The tip of target 9mm ammo gets hung in these magazines while loading and they are hard to free up. 125 grain hollow points fit better but the spring is so tight only 15 will go. Trust me, stick to you Glock brand magazines only.
