I have a couple of HE 32cal I-frames. I'm looking for a couple sets of modern made grips - don't want to screw up the originals through use. Checked various sites re: same and can't figure out if any are available. I-frame, 32cal. HE, etc don't compute in the listings far as I can tell. Any recommendations of how-to-find-some would be appreciated. (For example: everything works EXCEPT they list for J-frame). They're 1920 or earlier, I figure.
