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
