Great product! - Mean Arms 9mm Ejectored EndoMag - 3 Pack

Received these in a timely manner, thanks Optics Planet. Read the instructions carefully for sure, no big deal. Worked great in new Pmags. I highly recommend that you thoroughly break them in manually by repeatedly pulling back the charging handle while holding down the bolt catch so that BCG slides back and forth smoothly. I did it a bunch of times for each magazine to make sure they were fitting properly. Shot really well without any issues. I really like the look of the full size magazines way more instead of the Glock stick, they look a bit goofy in my opinion, even though I already have one in that platform lol. VERY happy about this purchase.
