Reason I ask is because last time I posted about the firearm I just bought I reported several FTFs and jams. I went to the range today and with one mag (15 round mag) jammed on me 2x's. The other mags that were designed for my gun (G-27) No problems at all, and the extended mag 22round had no issues. Used american eagle and winchester white box walmart. So Im wondering what the heck is going on.. I been to the range 3x with this new firearm, 1st time no issue, second time many jamms, and this time much better.. Perhaps I oiled the gun too much or it was the ammo I used last time, which was either Lawman or PMC.. Its my carry weapon so I want to be assured that it will work if I need it. Dispite the jams it was a simple re rack or tap and rack, but I dont want that, as time is not on our side in a firearm fight, every second counts.. BTW I did not try the new asian military 31 round mag, mabey next time.. all other mags are factory.. Snappy little gun, but Its a good little firearm.
