I just picked up a Smith & Wesson Model 13. Mechanically it's in good shape, but the finish has seen better days. There's no real pitting; the gun feels smooth to the touch. It's mostly just discoloration of the blueing. I plan to send it to the S&W Performance Center to have it refinished and to have the cylinder holes chamfered. Just wondering if you guys think I should go with the polished blue or the bead-blasted matte finish. I'm leaning towards the matte blue, as it seems more practical (and is less expensive). Also, do you guys think I should I have the cylinder release replaced with the modern version or keep it original?
