Sylvan Arms Glock 19 Gen 4 Custom Slide – RMR Cut – Black DLC – GL19G4PK
The Sylvan Arms GL19G4PK (UPC: 811313033476) is a precision-engineered upgrade for the Glock 19 Gen 4, designed to bridge the gap between factory reliability and custom performance. Machined from a single billet of 17-4 stainless steel, this slide is heat-treated for maximum durability and finished in a premium Black DLC (Diamond-Like Carbon) coating. This finish not only provides a sleek, low-friction surface but also offers industry-leading resistance to scratches, corrosion, and the typical wear associated with daily holster carry in 2026.
This "PK" model is a complete slide kit, meaning it comes pre-installed with all necessary internal components (firing pin assembly, extractor, and safety plunger), significantly reducing assembly time. The slide features an integrated Trijicon RMR footprint optic cut, allowing for the direct mounting of the most popular red dots on the market. To ensure maximum versatility, Sylvan Arms includes an RMR cover plate for iron-sight-only use, along with a specialized adapter plate, locating pins, and screws to support a wider array of micro optics. With aggressive front and rear cocking serrations for effortless slide manipulation, the GL19G4PK is the definitive "plug-and-play" solution for modernizing your Gen 4 Glock.
Includes: (1) Sylvan Arms G19 Gen 4 Custom Slide, (1) Set of Installed Internal Components, (1) RMR Cover Plate, (1) Optic Adapter Plate, and Mounting Hardware. (Does not include barrel, recoil spring, or sights).
