The G20 SF (Short Frame) variant trims the grip circumference and shortens trigger reach, making this full-size 10mm easier to handle while retaining the robust capacity of 15+1. This example is the Gen 3 configuration with finger grooves on the frontstrap and a non-ambidextrous magazine release.
It is built around Glock’s striker-fired, short-recoil, locked-breech action with the Safe Action system and a trigger safety shoe. The pistol uses a steel barrel and a durable polymer frame, and it is equipped with fixed notch-and-post sights featuring a white-dot front.
A Glock Universal (1-slot) accessory rail is molded into the dustcover. The SF frame does not use interchangeable backstraps, keeping the grip profile consistent and streamlined.
Manufactured in Austria, this pistol bears Austrian proof marks along with the factory “MADE IN AUSTRIA / GLOCK, INC., SMYRNA, GA.” rollmarks. Matching serial numbers were observed on the slide and frame plate, highlighting factory consistency.
The bore presents in excellent condition with a mirror finish, and the package includes two factory 15-round magazines, a Glock hard case, and an OEM magazine loader—ready for range or duty use with the powerful 10mm cartridge.
