Just recently a friend showed me his 22/45 with cocbolo stocks. I like the grip frame much better than my Ruger Liberty model 22. Mine is very accurate and has a Bomar solid rib on it. Can the top ends and frames be swithed on the new 22/45s and the old (made in 1976) Ruger 22s? I tried to search 22/45s on this forum but the search failed. Thanks.
