My P-09 is a '16 model and has proved 100% feed reliable with all kinds of ammo. The only limitation is OAL because of the short throat. It's the shortest of all my CZ's by a few thou, so when I want to try reloading with a new 9mm bullet, I just use the P-09 barrel for drop and turn measurements. Mine has proved to be very accurate, soft shooting, and the SA trigger is fine with no mods. These guns are a bargain!
