Anyone familiar with the Rossi 462 ( ss 357 mag snub ). I am looking at bobbing the hammer and getting some new grips. Is it a true J frame ? Will J frame grips fit ? I have heard people debate whether it is J frame, or K frame or neither. As far as trigger, would it just be one that would fit a 38 snub - are they fairly generic as long as it is the right type ( firing pin mounted, flat, etc. ) ? Thanks
