One thing I don't see mentioned is the quality of the new vs older revolvers.
Neither the new Colt or S&W offerings are as smooth operating as the older models of the same type.
I have a full size Colt 22 revolver that was used by the Toronto Police as a training piece. It functions through both double and single action buttery smooth and because of that, accuracy in both functions is very good.
I have S&W revolvers dating back to 1917 and their actions are equally as smooth.
I've tried the more recent manufactured pieces, offered by both companies and frankly, I'm disappointed in their smoothness.
All of the new revolvers I've handled over the last five years or so would have gotten trigger jobs and some honing if they were mine.
Ruger revolvers have always had gritty actions but were priced accordingly.
Taurus revolvers (S&W clones) were slightly better than Ruger and usually more accurate.
I recently shot an Alpha Proj and frankly, I was disappointed in it's operation as well. Price was good though and if the owner has the time and skills to smooth them up, they should be OK.
The very crude and cheap Arminius revolvers were OK but they didn't stand up to heavy use.
The old Iver Johnson revolvers were barely functional in my mind, but again, very cheap.
Other classics, like Korth from Europe are dreams come true as far as fit, function, smoothness and reliability go, but you definitely pay for it all.
Some of the French, Italian and Belgian knock offs can be very good as well and if they aren't, can be tweaked to a much higher standard.
