I am next to positive these are XR3 size grips. When laid on a 3" x 3" square they seem to match exactly with what the XR3 size is. I just know they were bought for a NMBH I have and they did not fit. I do not have a XR3 size frame myself to try them on. If your interested, and not sure if these will fit, take your current grips off and lay them on a post-it note like I did in the picture below. Seems like that should be a pretty good way of knowing they would work or not.
I have had them couped up for a while now and the screw and brass inserts are starting to corrode.
I figured it would be a cheap way to have a blank slate to play with shaping or trying your hand at checkering.
