my dad has this old Spanish 38 long colt apache revolver that he wants to fire after having it for a year or so. My question is ...is it possible to replace the long colt cylinder with a 38 special cylinder? Will it fit? Would it need specific tooling ? Cost too much if it is possible ? I'm just curious cuz i don't want him buying and trying to fire bullets that will more than likely ruin the gun ...or worse injure him ....apologies for the novice question but I dont normally do anything with guns and the one I recently bought is nothing like what hes trying to use ...thank you for any help anyone can give
