Vlim,
As for .45 ACP, the only revolvers I am aware of are the M1917 Colt and S&W, and the .455 Webleys with the cylinder cut for .45 ACP. I have a Webley Mk. VI cut for .45 ACP that I like very much: smooth, light trigger pull for a double action and very good accuracy. I load .45 Auto Rim cases with .455 bullets using .455 Webley dies.
Of course there is an endless variety of .45 revolvers for other cartridges. On my wish list is the newly-manufactured Merwin Hulbert available in .45 Long Colt.
