It would be interesting to take an air weight with "the crack" remove the barrel, coat threads with Belsona, an industrial 2 part metal epoxie, then shoot it to see when it failed. Might be surprised by how long it lasts, but I could never really trust it. But, let me ask this.. If it fired once would it be as trustworthy as one without the crack that may well crack on the very next shot fired???

I picked up a very nice alloy pre model 38 and have never fired it. I guess it is my safe queen.
