I bought a lot of grip screws from eBay for the S&W grip screws that the lot contained. In addition to the S&W grip screws, the lot contained a few screws that don't fit anything I have. The screw head diameter is 0.23", shaft diameter is 0.11", and length is 1.08". (see attached photo)
I'd appreciate help to identify what they may fit...Thanks.
Too big for a Colt Trooper, wrong style for a Detective (1954), 1903 Hammerless, and obviously not a 1911.
They are too fine/small for any of the rubber grips have that fill a shoebox. It is very similar to a set of Herret J frame wood grips but fits the threads too loosely. I don't have any Pachmayr wood grips. The link below takes you to a comparison photo between the mystery screw and a Colt Trooper and Pachmayr rubber grip screws.
