Rival Arms Glock 43/43X A1 Slide — QPQ, RMS Optic Cut

Description

Rival Arms’ Precision A1 slide is designed as the foundation for a Glock 43/43X build, combining modern features with broad parts compatibility. The match-grade slide is CNC machined from 17-4PH stainless steel billet and finished with a Quench-Polish-Quench (QPQ) thermo-chemical hardening process for improved wear resistance. It includes front and rear serrations for secure manipulation, three window cuts to aid cooling and airflow, and an RMS optic cut for mounting compact red-dot sights. Each slide is individually hand inspected and intended for direct installation without gunsmithing in most builds.
