This thread had me checking my 19-3 with a 10x magnifier, LOL. It’s 48 years old and the cone and top strap look factory fresh. Carried much, shot not much. That said, I carry it EDC with 125 grain Remington Golden Sabers. But I don’t shoot .357 or even .38+P at the range, I shoot standard .38 Special. No need to tempt fate, given that I really like it and S&W doesn’t have replacement barrels anymore. I’d guess that the current two-piece setups couldn’t be retrofitted to it if something went wrong.
