First picture a M66-3 and M686-3 S&W .357.
Second picture a S&W 60 (no dash) and S&W 66-4 .357.
And third picture a S&W 640 with Secret Serivce stocks, Ruger SP101 DAO also with SS stocks, S&W 60 with banana grips, and Ruger SP101.. all .357s.
Any and all will do for CCW but... the pride of Deaf Smith's little collection is...
A S&W M66-1 and Ruger Security Six I converted to RB (round butt) both with Secret Service stocks. The Security Six is a bit heavier but can take alot of .357s while the S&W Combat Magnum has a slicker trigger.
Again, either one will do to ride the river with.
My S&W 65-5 'LadySmith' is right now at a gunsmith getting a red insert front sight but later (I hope before Christmas) to have it back in the fold.
