Has anyone had problems with PMAG magazines? I have my carbine set up for Glock mags. I bought a couple of 27 round PMAGs for my carbine because the factory Glock big sticks were not available at the time. I’ve had numerous problems with them that I do not have with the factory Glock 17 round mags. They don’t happen consistently but they happen enough that it make me leery of using them. They have been:
Failure to feed. A bullet gets hung on the feed ramp.
Failure to lock the bolt back on an empty mag.
Failure to fire (the bolt looks to be completely in battery. I pull the trigger and hear kinda a “boing” sound like a spring makes. Nothing happens. I drop the mag, rack the bolt, the unfired cartridge is ejected, there is no primer strike, I put it back in the mag, reinsert the mag, drop the bolt and it fires this time when the trigger is pulled).
Failure to fire (the bolt looks to be completely in battery. I try to pull the trigger but it feels like it is locked and won’t move. I drop the mag, rack the bolt, the unfired cartridge is ejected, I put it back in the mag, reinsert the mag, drop the bolt and it fires this time when the trigger is pulled).
This seems to me like magazine driven problems. I’m going back out tomorrow and and will put a couple hundred rounds through it using the factory Glock 17 round magazines just to make sure they work well. My gun is not stock. I have installed the MCarbo flat trigger and shock buffer. But, I don’t think that is the problem.
