There are other aftermarket grip makers ..some from Thailand..that produce diamond target grips w pins..I believe S&W, in recent yrs, have used aftermarket grips since they stopped producing their own yrs ago..
Do they have the metal black or silver washers
on their backsides indicative of factory S&W
production? S&W did use some washerless
stocks in the later 80s 90s time frame but none w locater pins that I know of..
