The SF (Short Frame) variant reduces trigger reach while keeping the full-size profile and 13+1 capacity of the Glock 21. This example uses the Gen3-pattern frame with a single-slot Glock accessory rail and the Safe Action, striker-fired system. Construction pairs a steel barrel with a durable polymer frame.
The slide features rear-only serrations and is treated with Glock's ferritic nitrocarburized/Tenifer-type finish. Factory markings include "AUSTRIA" on the slide, "MADE IN AUSTRIA / GLOCK, Inc., Smyrna, GA" on the frame, and a Glock logo with "AT" on the barrel hood.
Sight picture comes from TG-H3 tritium 3-dot night sights with green lamps front and rear; the rear sight includes an ace-of-spades symbol. An aftermarket two-tone trigger shoe with a red safety lever is installed, and a rubber slip-on grip sleeve with palm swell and checkering enhances purchase.
