We will vent your existing S&W factory barrels! Very cool look, and reduction in weight! There are several different variations of the factory barrels, in most cases we can do them. Please contact us and we can tell you for sure if we can do the barrel you have. However the one that can't be done is the 5.5" barrel that has the "ribbing" on top of the barrel that ends right at the front sight. If the ribbing continues up on the front sight then its okay. We will include hot rebluing the barrel after machining. We recommend having the slide reblued at the same time for an exact match.
Please note if you have a newer model 41 that has the "etched" or laser engraved markings on the barrel, we can't unfortunately preserve that during hot bluing process. Also please note the barrel shown in the picture had the optional Dan Wesson interchangeable sights conversion along with the fiber optic sight-neither are included with the venting service.
