I was told that they are Mac-Gar manufactured. Sig did change out all the magazines with Mac-Gar I think with different springs, they had the same problems. Their duty ammo is HST 147 standard so I would expect range ammo to be similar. The problem seems to correct itself with some break in. The last I heard they are still loading 16 instead of 17.

I purchased a 9mm 320 Carry Tacops a week ago. Took it home and cleaned it then was off to the range. I shot 300 rounds total. 100 Rounds of Federal Champion 115gr cheap stuff unsuppressed and no problems. Mounted my Dead Air suppressor (Dry but wiped) and the problems started. Failure to eject was the issue. I was using the same Fed Champ ammo. I figured it may have been the recoil spring, but I don't know for sure. Switched to shooting unsuppressed and the gun ran great again. I finished the 2nd box of 100 rounds.

I then switched to Federal aluminum cased 115 grains and it ran just fine unsuppressed. I figured I'd try the can again for the last 50. Ran just fine! The ejection was a little weak though.

My 229 wouldn't work with Blazer brass .40 until I had about 500-600 rounds through it, now it eats anything. I'm pretty confident the 320 will be the same, but I still need to try subsonic rounds.

I just wanted to clarify something. The problems I had with my P320 were my caused by me, not with the pistol. I had adjusted my suppressor to change the POI and when I did, I didn't set the piston all the way into the groves at the base of the blast chamber. This coupled with a dry and dirty chamber caused the malfunctions. I was able to replicate the same problems the next day at the range. Sorry to take so long to make the correction. I just forgot, gun runs great, no exciting problems to deal with.
