I have a couple and have sent thousands of rounds down the line, two - three hundred rounds in an evening is quite common. Aside from replacing the recoil pad, I have had zero issues with mine. I clean mine when it starts to stick and doesn't cycle the slide enough to load the next round. Is that what you are experiancing? What ammo are you using, I've had the best luck with Winchester 22 Target. It's a little lighter load which keeps the gun steadier between shots.
