With DA/SA revolvers I probably have too many. Below a 686 no dash and an early Ruger GP100 of about the same vintage.
A Colt Python. I bought this when Colt was still making them for about $1K. Wish I had bought a few more back then.
These are interesting and no longer made. Taurus used to make them. They are 5 shot revolvers in 45ACP. The one on top is in SS and the one on the bottom is a Totally Titanium model. It does have a thin SS rifled insert for a barrel and most the lockwork appears steel.
And thinking of Titanium a S&W 325PD with Scandium/Aluminum alloy frame and Titanium cylinder. Lovely pistol.
And a S&W 625 which has the best DA trigger pull of any factory SA/DA revolver I every bought.
