ONLY way to know for certain if the gun was shipped as an "X" (convertible ) is through the factory and NO, this does NOT say or mean the cylinders currently in the gun are the ones that were shipped, NO ONE can say that with certainty, must check for the timing, lock up, fit and finish, and make an "educated" guess..if it times , locks up and "works" and "looks" ( finish match) then the presumption is , they are.....................
many of us can tell in a glance if they are "correct" , all of the above, as well as just "how" they are marked with the electric pencil..............pictures would indeed "help" 8)
aside from all of the above, a "cost" ( how much you paid for the gun) will make it more or less "painless" sounds a bit like you have buyers remorse (second guessing your buy?)...if "priced right", you should care less :wink:
