    What’s Included

    • 1x 10-round Glock factory .45 Auto magazine (Austria-marked)
    • Lone Wolf–marked stainless extended threaded barrel (installed)
    • Metal 3-dot dovetail sights (installed)

    This Glock 21 is a late Gen 2 transitional, often referred to as the 'Gen 2.5,' combining molded finger grooves with a frame that has no accessory rail. The slide uses rear-only serrations, aligning with the era’s configuration and giving the pistol a clean, uncluttered profile.

    The installed Lone Wolf stainless barrel measures approximately 5.25 inches and is threaded. It provides extended length over standard, with stainless construction and a clean crown, complementing the .45 ACP chambering.

    The slide presents a light metallic finish, distinct from the typical black, adding a unique visual contrast with the black polymer frame. Sighting is handled by metal 3-dot sights: a metal front with a single yellow dot and a metal rear with two orange/yellow dots.

    Markings include MADE IN AUSTRIA / GLOCK, INC., SMYRNA, GA. on the frame/slide, underscoring Austrian origin with import identification. The pistol is striker-fired with a short-recoil, locked-breech action and comes in a full-size format with a 10+1 capacity using the included Austria-marked factory magazine.
