I liked my friends SS 4" Path finder revolver. He's been having problems with it for years. After 20 rounds of CCI, carbon builds up on the face, and he has to use wire tooth brush and COMPLETELY clean the hand gun. He's a former cop, Sate Police and NRA firearms instructor.
I wanted the same gun, and called Charter Arms today if the problem still exsists. They said that all the revolvers had that problem.
I've got two Taurus revolvers that don't.
How about the S&W model 63, both old and new?
