I bought six and debating on buying 6 more. They work like a Charm, Excellent quality and my Glocks like them. The price was excellent.

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 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 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.

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.

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.

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 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.

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.

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......

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.

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 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!

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 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.

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 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’d 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 .

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.

Works perfect in my g17 s2k. locks releases and no fte or ftf.

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
