I bought one of these Uberti 1858's in the last year. Very impressed with how it shoots, once you figure out the sight picture. Unlike a lot of cap and balls, the Remington, mine at least, shoots very low. Have to use full post at 25 yrds to get POA. Changing cylinders if you had a second one would be easy, does take a little juggling to get it into the right position but, with practice this could be overcome. Have not used R&D conversion on mine. The Remington design sheds spent cap fragments far better than the Colt designs. Colts will often lock up when a hunk of cap gets into the action, rarely is this a problem with the Remington. The Remington design in general is more forgiving of fouling and less likely to lock up because of it when compared to others like the Colts of the same era. Two draw backs that I see with the Remington - most frustrating, none, or at least none that I have found, of the "cappers" can get to the nipples on the Remington's cylinder. You have to put caps on with your fingers - reallly slows down loading. Second, I strip my revolvers down for cleaning every time, the main spring on the Remington I find to be very difficult to get back into the frame. I eventually had to carve a piece of wood to fit the inside of the grip to bend the spring against to ease this operation. One other observation, #11 caps are what DGW recommends for ignition on this model. I have had 11's fall off nipples during firing - a very dangerous situation likely to cause a chain fire. I have gone to RWS 1075's and even used #10's with less problems. Suggest you test what ever caps you use by loading one cylinder, putting caps on the other five chambers empty and firing it, seeing if those other caps will stay in place.
