Finally get my gun back on Thurs July 27, paperwork says "Evaluate/Repair, Polish Barrel/Chamber, Passed Range Testing". When I sent the gun back I was told only to send the gun nothing else. Got the gun back they included another 7 round mag. Finally got to the range today, new mag worked fine. Put another mag in from original purchase, fired one time and hung up, didn't feed. Fired the the rest of the mag after ejecting the mag and tapping the mag to seat bullets. Tried the other 6 round original mag, same thing, miss feed. Put the new mag in worked fine. Put a few more mags through and worked fine. Put original back in, fired once and miss feed. Something must be wrong with the original mags. I'm using FMJ Sellier & Bellot ammo. Disappointed.
