Fits 2 1/2" model 19, model 66, model 10 etc. Should fit any snub nose knife frame. I tried it with my 4" M-64 and it fit perfectly except the bbl stuck out the bottom a little bit. It would work with longer barrels but is molded for the 2 1/2" bbls.
$39 shipped to the lower 48. AK and HI add $3.00 SOLD and shipped
