I have a G23 with the finger grooves in the grip and an accessory rail, and the older G22 without these features. I am going to convert one of them to .357 SIG and need need a clarification. I have been told that it is no problem to rebarrel the G23 to .357 SIG because it has the newer, stronger frame as evidenced by the finger grooves and the accessory rail.
I have also been told that my older first generation G22, not having the modified/fortified frame, is not a good candidate for the conversion. My preference is to convert the G22, which will have a higher velocity potential due to it's longer barrel.
What say y'all?
Thanks,
