I bought Ruger LCP II at one of my local gun shops yesterday. I went straight to the range from the store. Cleaned it up some and shot 100 rds mix of Geco and PPU ammo that I had laying around. I experienced constant failures to eject, had to pull brass out of the chamber with my fingers sometimes. Went home cleaned it, put it away, and made plans to go again today. Bought some WWB and Remington FMJ, and some various self defense rounds this time around and another box of the Geco from my ammo stash. First 50 rounds or so, same experience, ejection issues. Next 50 rounds, they were less often. Next 50 rounds, no matter what I fired, it worked 100%. Mixed up rounds in the mags, still no failures. I think it just need a little break in time. Nice shooting little pistol.
