Picked up a Ruger LC9 and a couple of factory mags and got to try it out today and will need far more trigger time before I will either carry or sell it. I had 4 different brands of ammo, first mag fed well, second mag 2 FTF, one cartridge didn't have a mark on the primer. I ran a few mags of everything I had, mixed them up and got 3 FTF on different brands in the same mag. It ran on Federal JHP but I the FTF without a scratch on the primers bothers me. I had one FTE also. Stripped it and could see marks on the left side of the feed ramp. Will take a very close look tonight but I am less than happy and won't carry it until I trust it. Does this have a break-in? Couldn't find any info if it does. Back to my Glock 23 for everyday or a J frame, even a 45 these I trust.
