I am much more fond of my 1954 Centennial Airweight and my 1962 Mod 40 than my Mod 640, but I still have the grip safeties on both pinned in so they can be shot without depressing the grip safeties.

It's moot anyway, but I bought the Bodyguard Airweight so I wouldn't be temped to carry the two older beauties. I also have a 1962 Mod 37 that I was going to use in the carry role, but I found the hammer did hang up in T shirts and front pocket carry and I didn't want to bob the hammer on such a nice Mod 37, so I bought a 1970 or 1971 Mod 38 which I carry almost every day. I guess I just like J frames a lot!
