The G20SF Short Frame geometry reduces grip circumference and trigger reach compared to the standard G20, while retaining the full-size Gen 3 format with finger grooves. It features Glock’s Safe Action, striker-fired, short-recoil system with trigger, firing pin, and drop safeties. The frame includes an integral single-slot accessory rail, and the slide uses rear-only serrations.
This example is Austrian-produced and proofed. The slide legend reads "GLOCK 20 AUSTRIA 10mm Auto," and the barrel hood is marked "10mm Auto" with an Austrian proof and the Glock logo over "AT." The slide, barrel, and frame bear matching serials that align with the factory case label.
Upgrades include a Trijicon-marked front blade for a crisp, high-visibility sight picture and an aftermarket grip accessory for added purchase. Gen 3 cues are present throughout, including the finger-groove frame and the absence of interchangeable backstraps.
Chambered in 10mm Auto, this pistol uses a 4.6-inch steel barrel. Capacity is 10+1 as configured with the included 10-round magazines. The package is rounded out by the original Glock factory case, making it a ready-to-go setup with useful enhancements.
