Glock 20 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 Ergonomics

The Glock 20 has a much longer and wider grip than the 9mm and .40 caliber Glock pistols.  Luckily, its controls are all in the same place, including the reversible magazine release, slide lock, and takedown bar.  Its slide serrations definitely help the user pull the slide back as the recoil spring is noticeably heavier.

Glock 20 Fit & Finish

The build quality of the Glock 20 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.
