So far I've put 121 rounds of 115 grain FMJ through the P-11. No missfires, fail to feed, fail to eject, etc. I'm really quite pleased.
The brands of ammo I've used so far are American Eagle, Remington, and Brown Bear. No problems with any of them. My next pay check I'm hoping to pick up a box of HP so I can test out which HP rounds work best in the P-11.
I'll post pictures of my targets soon. The P-11 seems to want to shoot high left, so I gotta counter act that by aiming low right. Anyone know if there's a way to adjust the sights on the P-11? The owners manual didn't say anything about it, and I think it did mention they were fixed sights. Can't remember.
