Glock 17/47/45/34 +2 Magazine – 19-Round 9mm Factory OEM Magazine | Black | Extended Baseplate

The Glock 17/47/45/34 +2 Magazine is a factory OEM extended magazine providing 19 rounds of 9mm capacity through the addition of a black extended baseplate to the standard 17-round Glock full-size body. Built to Glock’s exact manufacturing tolerances with a polymer body, full-length hardened steel insert and feed lips, and Gen 5 high-visibility follower, the Glock 17 +2 19-round magazine delivers factory-verified reliability in an extended format — adding two additional rounds over the standard flush 17-round magazine while providing an enhanced grip surface for faster, more positive reloads.

Why the Glock 17/47/45/34 +2 Magazine is the Extended Full-Size Glock 9mm Magazine

19 Rounds of 9mm — Maximum Capacity on a Standard Full-Size Glock Body
The Glock 17/47/45/34 +2 magazine provides 19 rounds of 9mm capacity — two additional rounds over the standard 17-round flush Glock full-size magazine. For duty use, home defence, and range training where every additional round matters, the +2 format maximises on-board capacity on full-size Glock platforms without switching to a 33-round extended magazine. The two extra rounds provide a meaningful buffer before a reload is required in a defensive encounter.

Extended Black Baseplate — Enhanced Reload Surface and Positive Grip
The Glock 17/47/45/34 +2 magazine’s extended black polymer baseplate provides additional surface area at the base of the magazine for a positive grip during emergency reloads and for stripping a stuck magazine from the well under stress. The extension improves both the speed and consistency of reloads by giving the shooting hand more surface to contact during the magazine change.

Polymer Body with Full-Length Hardened Steel Insert and Feed Lips
The magazine body is constructed from Glock’s high-strength polymer over a full-length hardened steel core and feed lips. The steel feed lips maintain consistent geometry and tension under sustained use, temperature extremes, and repeated drops — ensuring reliable feeding shot to shot over the full service life of the magazine. Rear witness holes allow round count confirmation without removing the magazine from the pistol.

Gen 5 High-Visibility Follower and Ambidextrous Magazine Release Cuts
The Glock 17/47/45/34 +2 magazine features Glock’s Gen 5 high-visibility follower for instant visual and tactile confirmation of an empty magazine, and the body is cut to accept both left-hand and right-hand magazine releases for full ambidextrous compatibility.

Wide Pistol and Carbine Compatibility
The Glock 17 +2 19-round magazine is compatible with all generations of Glock full-size and crossover 9mm pistols including the G17, G47, G45, G34, and G19X, as well as a wide range of popular pistol calibre carbines that accept Glock-pattern double-stack 9mm magazines.
