I had overwhelming urge and impulse bought my first revolver, a K-frame S&W 547 and three speed loaders, but otherwise I'm clueless about everything else. Currently, there are Pachmayr rubber grips on it but I'd like to get something better and could use recommendations on a holster too. Any tips or advice for a new wheel gun owner? Like how can I help reduce or prevent a ring from building up on the cylinder? How often should I replace the springs on the inside?
