Well, when I first got the handgun, I was using some "shooter's choice" brand cleaning solvent and lube, and I got a lot of stovepipes (1 every 200 rounds) for a while. Then I switched to a blue wonder kit. I think disotech XFR is a very good lube, since I NEVER had a jam after that. Never. I use Blue Wonder armadillo on the outside of the frame to make it waterproof and protect it instead of XFR. I think Fast Blast is kinda crap even though it gets to places where my brush won't reach, because it doesn't seem to clean anything away. Who else uses Blue Wonder?
