The Glock 21 SF (Short Frame) variant shortens trigger reach for improved hand fit while maintaining the model's full-size .45 ACP capacity of 13+1. This Gen3 frame configuration does not use interchangeable backstraps and incorporates finger grooves with pebble texturing for a steady hold. The magazine release is the standard left-side design, and safety is provided by Glock's trigger safety system.
The 4.61-inch steel barrel uses polygonal rifling and a ferritic-nitrocarburized treatment. The slide wears a matte black finish with rear serrations for positive manipulation. A loaded-chamber-indicator extractor provides a visual and tactile status check.
Fixed 3-dot sights (front dot, rear two-dot) offer a straightforward sight picture. The polymer frame includes a Glock accessory rail with a single cross slot for compatible lights or accessories. The pistol is full-size, built for .45 ACP, and configured to Glock's standard 13+1 capacity.
Origin and markings are clearly documented, with Austrian proof marks on the barrel hood and the importer mark "GLOCK, INC., Smyrna, GA." Additional Gen3-specific traits include the rear-serrated slide, polymer frame construction, and the SF profile that reduces reach without changing the pistol's overall size class.
