## Description

The Glock 20 (Gen4) MOS is a 10mm Auto pistol with a ported slide and barrel for reduced muzzle rise.

## What Customers Say

*AI-generated insights from customer reviews*

The Glock 20 has a long-standing reputation among 10mm shooters for reliability, and the Gen4 MOS ported variant carries that reputation into an optics-ready package. Some owners like being able to run a red dot without sending the slide out for milling, though a few note that adapter plates add another point of fit to get right.

Ergonomics follow the familiar Glock formula: a blocky grip that many find easy to control despite the size of the frame, though shooters with smaller hands sometimes find the grip circumference large for a duty-size 10mm gun.

On value, the ported slide and MOS cut put this model above a standard Glock 20 in price, and opinions split on whether the porting meaningfully changes recoil in practice or mainly adds muzzle blast and noise.
