Rival Arms Extended Polished Stainless Slide Lock for Glock 43/43X/48 - RARA80G003D

If you carry a Glock 43, 43X, or 48, you know the factory slide lock can be tough to manipulate—especially with a full grip or gloved hands. The Rival Arms Extended Polished Stainless Slide Lock upgrades that control point with a larger profile and premium finish. Built for shooters who want easier slide manipulation without replacing the entire slide, it's a straightforward, affordable way to improve your carry gun's usability.

This is a direct replacement for the OEM slide lock on compact and subcompact Glocks in the 43 family. The extended design gives your thumb or finger more purchase when locking the slide back for press checks, administrative unloads, or malfunction clearance. Polished stainless construction resists corrosion and pairs well with both factory and custom slide finishes.

Rival Arms focuses on functional upgrades for Glock pistols, and this slide lock reflects that philosophy—no unnecessary complexity, just a bigger lever that works. It's the kind of part that makes daily carry smoother and faster reloads more reliable, especially if you're running your 43X or 48 as a duty or defensive gun.

Key Features

• Extended profile for improved thumb purchase and manipulation
