I could use some info on this. I have a Ruger OM, SBH, that a has grip frame different from later SBH's. A later SBH grip panel is too small, too short, and the angle is different. Is this one of the 300 first run SBH's? Serial # 19xxx. The gun is in about 98% condition, and I have the original box. I was getting ready to customize this gun, but do not want to ruin a collector, if it is. I would rather swap it off for another if it is a collector. Any info would be appreciated.
