I just came across a pair of these too for my 4 Taurus 431, at a local gun shop for $10. While the original wood grips looked great, they were on the thick side and really punished the base of my thumb. The profile of these grips fits my hand better and are decidedly more comfortable to shoot with. The finish was a little on the thick side and very glossy, but 30 minutes of elbow grease and a sheet of 1000 grit sand paper did wonders!
