Big Larry, I have the brother in SS, a M-67 from 1976, with target trigger and hammer. It's very good shooter with Std. Vel. .38 Spl. in it. (for target shooting) But, I have always used Win. White Box 125 gr..38 Spl. +P, since I like heavier recoil.
I've owned it for almost 50 years. After years of shooting, it was updated and refinished by S&W in 2011. I need to take a picture of it. Bob
