Glock 17 Gen 4 | 9mm Full-Size Pistol | 17+1 Capacity | Modular Backstrap | Safe Action System

The Glock 17 Gen 4 is the fourth generation of the world’s most widely adopted full-size 9mm service pistol, bringing the Modular Beavertail Backstrap System, reversible and enlarged magazine catch, rough texture frame, and revised dual recoil spring assembly to the proven G17 platform. Chambered in 9mm with 17+1 capacity, a cold hammer-forged 4.49″ hexagonal-rifled barrel, and Glock’s Safe Action System with three passive safeties, the Glock 17 Gen 4 delivers the same benchmark full-size service pistol reliability in a more ergonomically refined package suited to the widest possible range of hand sizes and shooting styles.

Note: Purchase of firearms in South Africa requires a valid firearms licence and compliance with the Firearms Control Act. This firearm is sold subject to applicable South African legal requirements.

What the Gen 4 Adds to the Proven Glock 17 Platform

Modular Beavertail Backstrap System | Three Sizes Included
The defining feature of the Glock 17 Gen 4 is its Modular Beavertail Backstrap System, allowing the shooter to customise grip circumference using interchangeable backstraps in small (no backstrap), medium, and large sizes. The beavertail extension on the medium and large backstraps fills the web of the hand more effectively for shooters with larger hands, reducing felt recoil and improving control during rapid fire. All three backstrap sizes are included with the pistol.

Reversible and Enlarged Magazine Catch | True Ambidextrous Operation
The Glock 17 Gen 4 features a reversible and enlarged magazine catch that can be switched from right-hand to left-hand operation without tools, providing true ambidextrous magazine release capability. The enlarged catch surface is easier to activate positively under stress and with gloved hands.

Rough Texture Frame | Positive Grip in All Conditions
The Gen 4 frame features Glock’s rough texture frame (RTF) finish providing a more aggressive grip surface than the Gen 3, improving grip security in wet, cold, and high-stress conditions without requiring aftermarket modifications.

Revised Dual Recoil Spring Assembly | Reduced Felt Recoil
The Glock 17 Gen 4 uses a revised dual recoil spring assembly providing increased spring mass and longer service life, reducing felt recoil and muzzle flip for faster follow-up shots and improved accuracy during rapid fire sequences.

Cold Hammer-Forged Hexagonal-Rifled Barrel | 4.49 Inches
The Glock 17 Gen 4 barrel is cold hammer-forged steel with a gas-nitrided finish and hexagonal rifling with a 1:9.84″ twist rate. The 4.49″ barrel provides a longer sight radius, slightly higher muzzle velocity, and a more comfortable shooting experience for larger-handed shooters compared to the compact G19 barrel length.

Safe Action System | Three Passive Safeties
The Glock 17 Gen 4 uses Glock’s Safe Action System with trigger safety, firing pin safety, and drop safety, all engaging automatically during holstering and disengaging automatically during the trigger pull. No manual safety manipulation is required for deployment, providing the fastest possible response while maintaining passive protection against accidental discharge.

17+1 Capacity and Wide Magazine Compatibility
The Glock 17 Gen 4 feeds from a flush-fitting 17-round magazine providing full-size service capacity as standard, with compatibility for 19-round and 33-round extended magazines for range and home defence use.
