Well, my project of "gradually converting my Rugers to Bisley grip frames" isn't going well, because the grip frames are harder to come by than the guns themselves!
Of course, one option is to buy-a-Bisley-gun, sell-a-regular-gun, and repeat that cycle until I'm done, but I tend to get mine pretty scratched-and-dinged from totin' & shootin', and I'm sure I'd take a loss, plus even though I like to buy guns, I just don't want to go through all that (maybe. . . because it would include also
selling guns...

).
Anyway, there's really only one I'm super-eager to turn into a Bisley - my 5'1/2" .44 Mag Stainless Blackhawk. I have a perpetually-backordered Bisley frame coming sometime before 2025, but I've been 'experimenting' with trying to swap frames, and now I realize why Rugers aren't all that cheap - there must be alot of hand-fitting the grip frames to the cylinder frames; neither of the two Bisley grip frames I have on other guns will come close to matching up to that .44 Mag's cylinder frame, and pretty much none of the Rugers of any type line up well at the top/rear joining between frames,
except with the frame they came with.
When I get my Bisley grip frame (may be many months, at this rate

), I'll be sure and post pictures of the 'fitting' process, because it sounds like it's going to be a much more involved process than I'd originally thought. I guess in the end that will make the gun all the more special once I've "converted" it. I may or may not go with the Bisley trigger, though, and I prefer the Super Blackhawk hammer to any of the others, so it could wind up a 'mutt' of a gun.
