OK, I am going to basically disagree with everyone and everything you have ever heard about brass framed revolvers. I think their reputation for weakness and frame stretching comes from the earlier generations of replicas made in the 1970's or so. I have observed some of those that seemed to have soft brass and wide tolerances allowing the cylinder to beat up the frame.
I bought a 2002 manufactured Pietta 1851 "Navy" .44 Caliber Brass Frame used off of a guy one time that had a broken hand spring for $40.
I replaced the hand spring and began shooting the ever loving snot out of the gun. I had very little in it and thought I would just see how many rounds it would take to shake it loose.
I used 40 Grains of black powder and a round ball, 30 grains of black powder and a 230 grain conical, 50 grains of Pyrodex and a round ball and 40 grains of Pyrodex and a 230 grain conical. The Pyrodex loads were very compressed with the 50 grain charge almost level with the top of the cylinder before seating the ball!
I would go long periods of time before cleaning it by simply spraying it down with generic WD-40 and wrapping it in a plastic bag before sliding it back in the holster. I fired it over 100 shots without cleaning it beyond wiping the residue off the cylinder sides and face occasionally.
I fired probably 400-500 shots through the revolver before a guy saw me wearing it in town after coming in from the deer woods during black powder season. I had just bought a steel frame version just like it used for $125, he offered me $150 for it as it sat, I took it out of the holster and handed it to him still capped and loaded as he handed over the cash.
When I sold it, it was just as tight and solid as the day I bought it 2 years and several hundred rounds later. The frame showed no signs of peening, looseness, or stretching whatsoever. Looking back I wish I would have kept it, as the steel framed gun that replaced it is not nearly as accurate.
I wouldn't hesitate to have that gun back, or another similar one of recent manufacture. Brass frames don't scare me a bit!
