Yes, but when was the last time you saw the brazened lug on a Model 21 come off? Probably never? I have owned 12 Model 21s. And there are three sets of 21 barrels on the internet right now. So, they aren't that hard to find. I wouldn't stop buying them because of rumors. I had one that doubled when I bought it, but other than that I have never had one malfunction. I'll stick with my 21s.
Good Lord.
A Model 21 does not have a “brazened” lump. It has a soft soldered dovetail lump, and, since the barrels are built of 4140 steel, which is a legendary barrel material, that is notoriously difficult to keep wet in a soldering operation, they are legendary for coming apart. Repairable, but, a big pain in the ass.
This guy has fixed more of them than you will ever own. He would be someone I would consult in the event I owned a gun with a failure to the braze holding the lump to the barrels, but, I’m pretty sure I already know what his answer would be. And, it wouldn’t be, “get a model 21”.
