re: .22 pistol recommendations

I have a Walther P22. It is kind of selective with ammo, but its a fun gun to shoot. I typically run CCI ammo through it, and it works fine, but if you're shooting bulk ammo, it can hang up every couple mags or so if you are rapid firing. Someone told me they brought theirs to a gunsmith and he did something to it and it'll cycle anything through it now. I might try and do the same.
