Respinding to Dalerj.
You're right, Uncle Mikes grips are hard to find, but I have one for ya!
I have an Uncle Mikes, model 59007, fits S&W J Frame, slight wear.
I also have a Hogue Monogrip, for S&W J Frame, Round Butt Rubber Monogrip.
AND
I also have a Pachmayr Gripper, Black Finger Groove, Smith and Wesson, Square Butt 2 -(also for J frame, I'm pretty sure).
Anyone interested please message me and make me an offer!
Thanks.
