Extended Slide Lock for Glock Gen 1–5 & G-Series Compatible Frames – Cross Armory

Description

The Extended Slide Lock for Glock® Gen 1–5 by Cross Armory is a precision-engineered upgrade designed to significantly improve slide removal for cleaning and maintenance while maintaining full holster compatibility.

Unlike many incorrectly labeled aftermarket parts, this slide lock is specifically designed for Glock Gen 5, while remaining fully backward compatible with Gen 1–4 models. Cross Armory engineered the correct Gen 5–specific geometry, including the angled top cut required to properly clear the barrel lug and recoil spring assembly—ensuring safe, reliable function on Gen 5 pistols.

Manufactured from 4140 ordnance steel and surface treated for enhanced corrosion resistance, the Cross Extended Slide Lock delivers long-term durability and consistent performance. Its extended but non-protrusive profile improves ergonomics and finger engagement without snagging or interfering with any style holster.

Designed for full-frame Glock models 17–41, this slide lock is also compatible with Polymer80 (P80) frames, G-Series platforms, and even Smith & Wesson SD series pistols, making it one of the most versatile slide lock upgrades on the market.

If you own a Glock—especially a Gen 5—this extended slide lock is a must-have upgrade to ensure proper fit, easier breakdown, and reliable long-term performance.
