I haven’t tried Magpul’s new Glock magazines yet. I’m always reluctant to go anywhere for a pistol magazine except the OEM source. I’m especially concerned about Magpul’s magazines not being metal-lined like Glock’s. Way back in the dinosaur days, Glocks mags were all plastic with no metal liner. When loaded, the mags would swell a bit and as a result, many more-than-empty magazines would not drop-free. It’s my understanding that the European methods of mag swapping involve stripping the mag rather than letting it drop free, so perhaps that wasn’t an issue. However, for the American market…us crazy Yank cowboys like our drop-free magazine changes.
An original 33-round Glock happystick is always going to be my first choice for this sort of thing. However, from an investment standpoint, if the Magpul offering is less than $20@ it might make sense to throw a few dozen back. If I ever get around to getting the 9mm Glock-compatible AR that I want, a couple dozen might be just what the doctor ordered.
I can offer an endorsement of the Magpul 9mm mags. They drop free of my G23 (with 9mm barrel) loaded or unloaded. Pretty good feel to them as well as they feel robust for the job. I’ve not torture tested the things at the gravel pit yet but 200 rds of 9mm through the Magpul mags was just like shooting the Glock mags, boringly reliable.
Palmetteo State Armory has gone that route also offering a billet lower that’ll do Glock mags: http://palmettostatearmory.com/ar-9-ar-47/ar-9.html
Looks like the 9mm AR is the new thing for 2016.
Shame… cause I could find a place for a .45 AR in the safe….
These magazines would also work in a Kriss Vector, presumably. Not a huge user base there, but still.
I have a couple for my Glock 19. I haven’t had any issues as of yet. Price is almost too good to pass up – if you can find them.
