Glock 20 Gen 4 Features

The Glock 20 Gen 4 is chambered for the hard-hitting 10mmAuto cartridge and has a 15-round standard magazine capacity.  Its barrel measures 4.61 inches long and its magazine release is reversible to accommodate both left and right handed users.  The reversible mag release can also make it easier for smaller-handed users to use their middle finger to press the magazine release instead of stretching their thumbs to drop the mag in the traditional way.

Glock 20 Gen 4 Capacity

Shipped with 10 and 15 round double-stack, single-feed magazines, Glock and other magazine manufacturers offer capacities of 18 and 30 rounds.

Glock 20 Gen 4 Ergonomics

Ergonomics
The Glock 20 Gen 4 is a full-size 10mmAuto using double-stack magazines, resulting in a grip that may be too large for users with smaller hands.  The serrations on the slide assist in cycling the action, and the magazines always fall freely when pressing the magazine release.  The finger grooves and Glock’s Gen 4 grip texturing give the user an excellent grip to help tame the 10mmAuto.

Glock 20 Gen 4 Fit & Finish

The build quality of the Glock 20 Gen 4 is exactly what you would expect out of any Glock.  The nDLC coating is consistently applied across the slide, and the polymer frame is free of any overpress defects from the injection molding process.

Glock 20 Gen 4 Concealability

Concealability
The Glock 20 Gen 4 measures over 8 inches long and 5.5 inches tall making it difficult for concealed carry without heavy clothing or utilizing a shoulder holster.  The Glock 21 is better suited for open carry or concealed winter carry.
