Doc:
We just talkin'
grip frames?
I recollect the XR-3 is the Single Six frame too.
You're right. There have been a whole passel of 'em---
Don't fergit the
other grip frames---Super Blackhawk, Bisley, Birdshead, etc.
But I recollect most all of 'em have the same screw placin' (common to all).
I will get the info & get back on the forum after work tonight.
Gotta fly!
