I have done some reading and what i have found out is, I have a 1860 ARMY, made in 1984. I bought a few things from a guy and this was one of the items. I have already torn gun apart and made a list of the broken parts needed to fire this gun. When I got this gun, it had a newer barrrel and cylinder, because previous owner bought a gun show and said they were in nice condition. So my first question is, i put the original barrel and clylinder back on and now i am not able to push the wedge all the way in. If i push it as hard as i can with my finger, it binds up the cylinder and it will not spin. Where the barrel meets up to the frame, it is very tight and correct fit. It looks as if the base pin needs to be pulled out slightly???? I have no idea what the right way to go about this is? Also, the cylinder does not slide over the base pin very smoothly. Wondering if I should just add a base pin to my list of things to order? If it might be a good idea to replace it, how do you remove the base pin? I do see that there is a a barrel pin, to help keep the base pin aligned, but the barrel pin looks like it can only be driven in when the hammer is pulled back.... I hope I have explained this correct. Any help would be greatly appreciated!!! One last add to my problem...the easiest way to put it, the wedge seems to be to wide and would need to be filed down. I just doubt that is the correct fix though.......
