Well, I have had this gun a while and never checked to see if the silly thing would chamber .357 Magnum shells....and, it does. If I had known that I would never have paid the money to have it lettered. Anyway, as I have gotten older, I've been trying to sell several of my guns and this was one of them. How much do you think the reamed cylinder affects the value at this point? Does it just kill it altogether. In case it matters, it's a pre-war model with all numbers matching.
