It works! First and foremost. Seemed a little flimsy, but it feeds just fine. I have not had them long enough to see how well it holds up

I would definitely buy this mag again and I recommend it.
No problems at all in my Glock 17 GEN 5.

Great back-up mag
I purchased this as a back-up mag to my Glock 33 round gen 4 mag. It doesn't look as pretty as that one but after 200 rounds I haven't had a single issue. Again I think it's a great second choice to the "happy stick".

Great quality, can't buy a better product
To be honest, I thought the mag had a steel liner similar to the Glock (use it with a magnet), though it's a great mag, I'm going to give it to a friend as a backup mag for her Glock 19. She'll love it. Thanks Cheaper Than Dirt and Magpul. ABM. ?

So far I've run about 100
So far I've run about 100 rnds through my 21 GL9. I have had one FTF out of the hundred. I'm very pleased with these magazines for general shooting practice. I'll review again when I've put more rounds down range. I'm satisfied with this product so far.
