I own, and have owned, quite a few different brass framed revolvers, including two in the dreaded 44 caliber. I have never had a single occurrence of a "stretched frame", or whatever the problem is purported to be. I have not always "babied" them either, although I do now.
I think the biggest concern with a brass framed revolver is to not use oversize balls in them. There does not need to be any shaved ring of lead. The ball needs to fit tightly in the chamber, no more. If the fit is too tight, there is excess stress put on the arbor as the bullet is seated. I think this is what damages the brass framed guns, to the extent that they get damaged.
