back about 1980,I came into possession of a Model 19 2inch for a song. The previous owner had dropped it and the thumbing spur had broken away leaving a jagged hump behind.. So I decided to clean it up and make a set of Iron wood grips for it. Figured I couldn't screw it up and I could always R&R the part later.
It was easy as pie. I used my moto tool to finish trimming the hump off, with a cutting disc, and a sanding attachment. (I went slow) Then proceeded to polish it with varying applications of compound with the moto tool buffing rubbers and cotton discs. It looked like a professional job.
The grips were a labor of love, and the moto tool was a major asset followed by my drill press.
I sold that pistol many years later.
