Zaffiri Precision® ZPS.2 Elite Complete Slide Custom Combo – Fits GLOCK® 19 Gen 5 – Black Cerakote Cut for RMR – Black Nitride Threaded Barrel – Blacked-Out Co-Witness Sights – Includes Pre-Installed Upper Parts Kit – CU-G19G5-ZPS2-RMR-BLK-TH-BN-BLNK
The Zaffiri Precision® ZPS.2 Complete Custom Slide and Barrel Conversion System for the GLOCK® 19 Gen 5 (CU-G19G5-ZPS2-RMR-BLK-TH-BN-BLNK) represents a masterfully engineered, match-grade tactical overhauling kit built to maximize sidearm tracking velocity, absolute mechanical precision, and optic implementation layout. While standard factory polymer-sighted slides offer robust, baseline military-grade service cycles, their thick, heavy industrial castings inherently maximize cycle mass—frequently causing excessive vertical muzzle flip, slow secondary target recovery tracking lines, and a lack of direct red-dot system architecture. The Zaffiri Precision premium custom layout completely upends standard factory parameters. This American-machined operational masterpiece (810220067048) arrives completely compiled as a drop-in match-grade upgrade, replacing standard components with a sleek, lightened upper built for defensive operators, red-dot competition shooters, and premium builders alike.
The structural foundation of this high-speed custom upper is anchored by the precision-cut **ZPS.2 Elite Slide, CNC-machined from a monolithic block of 17-4 PH stainless steel**. Engineered with aggressive geometric top and side weight-reduction port cuts and tight tracking tolerances, this slide drops reciprocating slide mass significantly to accelerate lockup times and flat-track your muzzle straight back down into target strings. Sealed in a deeply bonded, tactical Armor Black Cerakote ceramic finish, the exterior is explicitly surface-machined with a **Trijicon RMR/SRO footprint optic cut** (cross-compatible with Holosun 407c/507c/508t optics) alongside a matching hard anodized cover plate. Sitting perfectly inside the slide dovetails is a pre-installed set of premium **Blacked-Out Co-Witness Height Iron Sights**, providing an absolute, uncluttered lower-third optical backup reference window straight through your red dot's glass.
The true functional heart of this premium conversion system is its match-grade **Threaded Barrel chambered in 9x19mm Parabellum**. CNC-milled from 416R weapons-grade stainless steel with custom stress-relieved broach rifling (1:10" right-hand twist), this high-performance barrel is treated with a sleek, friction-free Black Nitride (QPQ) finish that yields supreme surface hardness and resistance to intense carbon fouling. Threaded in the standard **1/2x28 TPI pitch**, it opens up immediate staging paths for premium compensators or sound suppressors and ships complete with a matching knurled thread protector. Arriving with a **premium Zaffiri Precision internal Upper Parts Kit (UPK)** completely pre-installed—including the firing pin assembly, safety plunger, extractor, and a heavy-duty polymer channel liner—this drop-in ready package eliminates the need for frustrating bench tool assemblies or separate small-parts orders.
Includes: (1) Zaffiri Precision ZPS.2 Stainless Steel Custom Slide (Armor Black Cerakote / Gen 5 G19 Custom Geometry / RMR Optic Cut), (1) Zaffiri Precision 416R Stainless Steel Threaded Match Barrel (Black Nitride / 1/2x28 TPI), (1) Knurled Black Thread Protector, (1) Set of Blacked-Out Suppressor/Co-Witness Height Iron Sights (Pre-Installed), (1) Complete Premium Zaffiri Precision Internal Slide Parts Kit (Pre-Installed), and Original Factory Sealed Presentation Packaging.
*Drop-In Frame Fitment & Recoil Spring Calibration Note: This premium custom slide kit is meticulously configured exclusively for Generation 5 GLOCK 19 frames (and cross-compatible Gen 5 G45 or G19X frames). To finalize your installation string, simply swap over your original factory Gen 5 dual recoil spring assembly or an equivalent aftermarket guide rod into the slide framework, slide the complete upper unit directly onto your lower frame rails, and perform a standard safety function test cycle prior to firing live ammunition.*
