I have a LC9 and use Defend ammo for PP and have had an issue with the first round in the mag not loading when the mag is fully loaded with 7 rounds. When I only put 5 rounds in, it works fine. It seems to be a problem with that 1 mag, I switched mags and now is fine. I have 4 mags, all Ruger, and never had this problem with FMJ practice ammo. Has anyone else experienced this?
