Rival Arms Glock 43 Gen4 Black Upgrade Slide TGRA10G305A

Take your Glock 43 Gen4 to the next level with the Rival Arms Precision A1 Upgrade Slide—a serious performance upgrade engineered for shooters who demand rugged reliability, enhanced control, and custom-level accuracy. Built from a solid 17-4PH stainless steel billet, this slide is CNC-machined to exacting standards and finished in a durable black QPQ coating, offering outstanding corrosion resistance and long-term wear protection in even the harshest environments.

This upgrade slide is designed with match-grade precision in mind, giving you tighter tolerances and smoother cycling compared to the stock factory slide. The Quench-Polish-Quench (QPQ) case-hardening process not only deepens surface hardness but also adds a slick, low-friction finish that resists scratches, corrosion, and operational stress.

Three strategically placed window cuts along the slide improve cooling and airflow, helping maintain barrel temperature during prolonged shooting sessions. These cuts also reduce overall slide mass, enhancing cycling speed and responsiveness. Front and rear serrations offer a positive grip for fast, confident slide manipulations, whether you’re press-checking or working under pressure.

This version features a clean, no-optic-cut design, ideal for shooters who prefer iron sights or plan to add aftermarket sight systems. Every slide is individually hand inspected for accuracy and fit before leaving the factory, ensuring you're installing nothing short of elite-quality components.

The Rival Arms Glock 43 Gen4 slide is a true drop-in upgrade—no gunsmithing required. Whether you’re customizing your EDC, preparing for competition, or building a reliable backup, this slide delivers uncompromising performance and a tactical edge you’ll feel on the range and in the field.

Proudly made in the USA, Rival Arms stands behind their craftsmanship with a commitment to precision engineering and American manufacturing excellence. When it’s time to upgrade from factory to exceptional, this slide is the one to reach for. Order it today from SMKW!
