ive shot 100 rounds straight through my tomcat and no trouble, same mag and dirty.
its prolly more of a ammo problem than gun problem.
i havent shot any HPs out of it though, becareful what grain bullets you are using, the instructions say to not use more than 71gr, anything more might be too hard on the gun, the S&B is 73gr, FYI, i wouldnt use anything too light either.
your also NOT supposed to dry-fire this gun, which is a difficult thing to do since there is no slide hold open device, and unless you count the rounds you are gonna dry fire it every time on a empty chamber. ive heard of a few broken firing pins with this gun, at about the 1000rnd mark.
my remedy is to get a 32acp snap cap to be the last round fired in the mag, so the firing pin doesnt dry fire on an empty chamber, also you might want to get your hands on a couple extra firing pins.
i heard the trigger smooths out after about 1000 rounds.
