Hello all, this is my first post albeit long winded,i currently have 5 rugers-2 MKIIIs,a.44 alaskan,a .480 srh and today i purchased a circa 1982 stainless 7.5" old army in .45. I think i have a problem with the old army and would appreciate any input. I am new to cap and ball guns so perhaps it's something i'm doing wrong but anyway my problem is that if i cock the gun and ride the hammer down the cylinder,trigger and hammer lock up and i have to remove the cylinder and reassemble the gun to make it functional again.The indexing pawl(?)-the piece that rotates the cylinder has alot of sideways play in it.I cannot get the hammer into the notch between nipples either,the gun appears to have been very well cared for but is this problem common to cap and ball rugers or am i doing something wrong? I traded a used XDm even for this pistol and hope i did o.k. on the trade.Thank you to all that reply
