I had a Walther P22, accurate but too small for my hands. Pain in the ass to break down. I prefer the Sig Mosquito. Regardless, both work great with CCI Mini Mags and should not give you an issue with that ammo. Where people have problems is with cheap ammo and not cleaning the dirty 22 enough. Just my personal experience. I love the 22LR. Matter of fact, taking my Umarex HK MP-5 22LR and Sig Mosquito out to the range tomorrow with the Desert Eagle 50, MPA MAC-10, and Beretta 92. I love shooting cheap with the 22.....especially now since ammo can suck to find locally.
