The Noveske DM (Direct Mount) Slide and Pistol Barrel Set is an out-of-the-box upgrade to your factory Glock 17 or 19 pistol. Each set is configured with a Noveske DM Slide and Pistol barrel that features our iconic Cross engraving split over the top of each part, representing a factory set. Only our sets come with this detail! The Noveske DM (Direct Mount) Slide is an out of the box upgrade to your Glock 17 or 19 compatible pistol, providing the option of mounting a variety of optics to a single slide. Our patent pending DMOS (Direct Mount Optic System) allows mounting of 4 different optic patterns, utilizing our FMRS (Forward Mounted Rear Sight). The FMRS acts as a spacer, utilizing a dovetail design, keeping the optic as close as possible to the bore centerline. Lending to a smoother, repeatable mounting process and return to zero. The Noveske DM Slide features enhanced serration cuts front and back to increase ease of manipulation and includes a chamfered window on top creating a perfect weight balance. Each slide is made from 17-4 stainless steel and finished with a DLC coating. The Noveske DM Pistol Barrel features a 9mm match chamber cut with Single Point Technology (S.P.T.). This means the bore, rifling and chamber are cut in a single, high precision machine, which lends to an incredibly accurate pistol barrel. We’ve finished each barrel with an 11-degree target crown. 6 small flutes reduce weight and increase heat transfer. Each barrel is made from 416R Stainless Steel and finished with a DLC coating.
