Precision Machining & Premium Materials

The RA10G604A is CNC-machined from 17-4 PH stainless steel, chosen for its high strength, excellent corrosion resistance, and dimensional stability under cyclic loading. 17-4 stainless holds tighter tolerances and resists wear better than standard stamped slides, delivering consistent lockup and repeatable performance round after round.

Finish options include:

• Black QPQ (Quench-Polish-Quench) for a hard, corrosion-resistant, low-friction surface treatment preferred in tactical and duty applications.

• Case-hardened style finish (where specified) for a unique, vintage-inspired appearance that still maintains protective properties.

Both finishes reduce glare and protect the slide from the elements and daily carry wear.

Optics-Ready Docter Cut

The slide comes pre-cut for Docter-style red dot sights, making it optics-ready out of the box. The precision optic cut is machined to Rival Arms’ tolerances and includes properly located mounting points for adhesive plates or industry-standard footprint adapters. If you want a fast-acquisition red dot on a subcompact Glock, the RA10G604A lets you mount your optic without expensive gunsmithing.

Enhanced Slide Geometry & Serrations

Designed for improved manipulation, the Rival Arms slide features:

• Aggressive front and rear serrations for positive purchase during press checks and slide manipulations—even with gloves or wet hands.

• Lightened cuts and porting (where applicable) to reduce reciprocating mass and give a crisper cycle feel while maintaining strength.

• Refined ejection port and extractor channel geometry to promote reliable ejection and consistent case clearance.

These changes not only improve ergonomics but also contribute to slightly faster cycles and a cleaner ejection pattern when paired with a tuned recoil system.

Fitment & Compatibility

• Fits: Glock 26 Generation 3 and Generation 4 frames (verify Gen compatibility before purchase).

• Slide-to-Frame Interface: Machined to tight tolerances to ensure consistent fit, reliable feed, and repeatable accuracy.

• Barrel Compatibility: Accepts standard Glock 26 barrels and most aftermarket match barrels cut for Glock 26 slides. Confirm crown and length when mixing brands.

• Optic Mounting: Docter-style footprint; verify optic plate/adapter compatibility with your chosen red dot.

Performance & Reliability

Rival Arms designs slides for shooters who want enhanced function from a micro-compact platform. The heavy-duty 17-4 construction and durable finishes yield:

• Improved slide life and wear-resistance vs. stamped/slotted factory slides.

• Consistent lockup and repeatable zero when combined with quality barrels and sights.

• Optics-ready capability for faster target acquisition and modern defensive or competition setups.

When paired with proper springs and a matched barrel, the RA10G604A supports reliable cycling across a wide range of defensive and target ammunition.

Installation & Armorer Notes

• Drop-in replacement: Installation requires standard Glock disassembly and reassembly; no special tools are generally required.

• Barrel & Recoil Spring: Use a compatible Glock 26-length barrel and recoil spring assembly for best results. Some aftermarket springs or barrels may require timing or fitting—consult the manufacturer’s guidance.

• Optic Mounting: If mounting a Docter-style red dot, install the appropriate mounting plate and tighten to the optic manufacturer’s torque specs. Verify secure mount and check zero before use.

• Function Check: After installation, perform a complete function check, including slide travel, trigger reset, and safe firing verification at the range. If unsure, have a qualified armorer perform the install.
