The SF (Short Frame) variant retains standard G20 magazines and slide dimensions while shortening the trigger reach and reducing grip circumference. For many shooters, this improves control with full-power 10mm while preserving the G20’s 15+1 capacity and full-size handling.
Gen3 cues include finger grooves on the front strap, a small left-side magazine release, and rear-only slide serrations. The polymer frame is black with an integral accessory rail on the dustcover, and the backstrap features a relief cut at the magwell. The slide wears a matte black finish.
The 4.61 in steel barrel is cold hammer forged with polygonal rifling. This barrel construction is known for durability and a smooth interior finish, and the bore here presents as clean and bright. The Safe Action system provides three passive safeties typical of Glock striker-fired pistols.
Sights are the factory fixed polymer set with a white-dot front and a white U-notch rear that is drift-adjustable. Markings include "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA," noting Austrian manufacture with U.S. importer identification.
