I just did the same with my 3 inch 625-3 i took a set of N frame sq butt targets and put um on and with the help of a fellow forum member put in a piece of wood to fill in the gap they look great so happy with they way it turned out congrats on your new stocks
Gerry did a great job on the insert for me the target grips make the gun![]()
This is a walnut piece made to fill the gap left by round butt frame with square butt grips. I've done three of mine. Works slick.
