Up for sale we have Gen 3 Glock 21SFs with ambidextrous mag releases (rare). The Ambidextrous Gen 3s were normally only seen with Picatinny rails on the receiver as opposed to this version that has the factory Glock rail and ambi release. This will include 2 factory Glock magazines and an OEM Glock box. Pictures are reflective of the Glock 21SF you will receive as we have multiple available.
