The Glock 21 SF is the Short Frame version of the Glock 21, offering the same full-size .45 ACP format with a reduced grip circumference profile indicated by the "SF" marking. This example is clearly identified by factory and import/proof markings including "GLOCK (logo), 21, AUSTRIA, 45 Auto, SF" and "MADE IN AUSTRIA / GLOCK, INC. / SMYRNA, GA."
This pistol is equipped with fixed sights featuring white reference markings on both the front and rear, providing a straightforward sight picture.
