.38 special. Very tight mechanically. Pretty much no bluing just original patina. I bought this from shooters supply in Hutchinson when they were in business. I've shot the revolver and was always going to get a set of nice grips for it and eventually just gave up. Anyways it is what it is. If I don't sell this gun and your sitting on some nice wood grips: I'm definitely interested. I will entertain serious offers. Ftf transaction Kansas drivers, cash. As always thank you for looking.
