I really like Pmags but the inconsistency is getting to me.

I don’t own any Gen2 Pmags but if you want to make sure a Pmag drops free the windowed and 40 round Gen M3s all do as far as I can tell.

I measured my magwells against the drawing and they’re on the money. Some of the Gen M3s I have aren’t.

I have two LMT lowers. One purchased 2010 or so, the other in 2019. The 2010 model has zero problems with older Pmags. The 2019 model doesn't like my older Pmags, they stick. I keep the mags segregated for no bad surprises...

No problems also with my PSA lowers with Gen3 mags! All 15 of them never hung up!

Ahhhhhh nevermind.

I have had issues with PMAGs seating and dropping free in various BCM and LMT lowers.

I'm old and like Okay STANAG mags.
