Themes, eh? That’s a term I’ve never considered as applied to revolver stocks. Are you an author, artist, or musician by trade?
I’ve never found a grip or stock design I was totally satisfied with, so I keep looking, and keep accumulating stuff that doesn’t quite cut it, for one reason or another. Given my long-standing lack of success in this area, I guess a theme approach is as good as any.
I tend you follow along with the thinking of HRichard. The stocks that I use are in keeping with how I intend to use the particular gun they are on, and that most of my S&W revolvers do pretty well with the stocks they came with.
