Since my very first Smith & Wesson was a Chiefs Special in 1970, I've always been very fond of those J-frames.
S&W Model 637 w/factory rubber stocks.
The same Model 637 w/Magna grips from the S&W Store.
While my revolver is vastly more comfortable to shoot with the rubber stocks, I prefer the Magnas for concealed carry. Years of shooting with Magnas has allowed me to be quite accurate with this handgun.
