Kraigwy...I'd really like a spare cylinder (.45 LC) for that old M25 of mine ... any idea if S&W is still doing that? What a combination....I've got a Colt SAA in .45 LC (Yeah, I know the 'LC' is superfluous), to which I fitted a .45 ACP cylinder...and it's more accurate with the ACP than the original LC!...Shoots a mite low with 200 TWC's but is right on the mark with 230's.
