The Rival Arms Precision Slide A1 (brand part no. RA10G604A) is a match-grade upgrade slide built for Glock 26 Gen 3-4 pistols, and Rival Arms designed it as the foundation for a serious custom build rather than a cosmetic swap. The slide is CNC machined from 17-4PH stainless steel, giving it tighter tolerances and better corrosion resistance than a stamped factory slide, then finished with a QPQ thermo-chemical case-hardened treatment for added surface durability. Front and rear serrations make manipulation easier under stress or with gloved hands, and this Docter-cut version is machined for a direct-mount reflex optic without needing a separate adapter plate. Three window cuts along the top reduce weight and improve cooling and airflow during extended range sessions. It’s built for competition shooters, concealed carriers, and anyone upgrading a Glock 26 toward a true precision build.
