All numbers matching vs. not matching usually puts a gun in collectable condition vs. just a shooter, and the market recognizes that effect. A Brazilian Model 1917 must be further judged on condition to make it collectable vs. a shooter. Most of these guns show wear and sometimes abuse before they were reimported to the US market. I would not suggest snubbing a nice condition Brazilian, a well worn and abused Brazilian would make a good candidate for a quality alteration of the barrel length, however it's still a heavy revolver and concealed carry can be difficult.
