Do you ever actually follow up and buy anything? I see you posting for advice all the time, cannot recall seeing you actually buying anything.
Yup, forget the Colt 1892, it was not a great revolver.
Forget 41 Long Colt too, it has not been manufactured for eons.
The S&W 44 Double Action was mentioned. Here are a couple. The one at the top is a target model with windage adjustable rear sight and target front sight. It left the factory in 1895. The one at the bottom is a standard model that was refinished sometime in the past. The front sight on that one has been replaced with an old coin. It shipped in 1881. Both of these are chambered for 44 Russian which is commercially manufactured today, but I have no idea where you would find any today. This model was also chambered for 44-40, and a very few were chambered for 38-40. I paid $950 for the target model and $795 for the blued one a bunch of years ago. Good luck finding one today.
I DO NOT recommend firing these with Smokeless powder, I only fire them with my Black Powder hand loads.
I bought this EuroArms 44 caliber 1858 Remington way back in 1975. Have no idea what I paid for it back then. About 20 years ago I bought a 45 Colt conversion cylinder for it from Taylors. Probably paid about $180 for the cylinder at the time. I highly recommend Taylors, they fitted the cylinder to my old Remmie FREE OF CHARGE. No idea if they are still doing that.
I just checked Taylors website. You can get a Remington 1858 for $432.05 and a conversion cylinder chambered for 45 Colt for $256.47, which would bring the total to $688.52. DO NOT BUY A BRASS FRAMED 1858, AND MAKE SURE THE CYLINDER IS FOR 45 COLT, NOT 44 COLT.
If they offer to fit the cylinder to the revolver, take them up on it.
