On April 17, 2026, Glock, Inc. officially announced a new 15-round magazine for the G44 via @GLOCKInc on Twitter/X. The announcement grouped three magazines into a single May 2026 dealer release: the G43X and G48 15-round Slimline magazines, and this new G44 15-round rimfire magazine. The G44 is Glock's .22 LR training pistol, released in 2020 on the G19 frame footprint with a hybrid steel/polymer slide, and it has shipped exclusively with 10-round magazines since launch.

Glock has not yet published a model number, UPC, or MSRP for the G44 magazine. The announcement is a dealer-ship confirmation, not a full product spec release. Expect the standalone magazine to appear in distributor catalogs over the next few weeks as shipping approaches, with pricing likely in the $25-35 range based on current Glock OEM magazine MSRPs.

The G44 exists to give Glock shooters cheap trigger time. .22 LR ammunition runs at a fraction of 9mm cost per round, which makes the G44 an ideal platform for drilling fundamentals, working on transitions, and running new shooters through familiarization without burning centerfire ammo. The original 10-round capacity was a compromise between the G19's 15-round magazine and the mechanical reality of feeding .22 LR reliably through a double-stack polymer magazine.

Moving to 15 rounds brings the G44 to capacity parity with the G19, which is the whole point of the platform: a training analog that mirrors the centerfire gun you actually carry. During drill work, a third fewer reloads per string means more reps per session and less time spent loading mags between runs. For shooters using the G44 to practice standardized drills like Bill Drills, El Presidente, or dot torture, capacity parity with the centerfire gun eliminates the mental asterisk of "I ran out before the real pistol would have."

A 15-round G44 magazine is an obvious and overdue addition. The G44 has always been pitched as the G19 training counterpart, and capacity parity removes the last gap between the two platforms. For existing G44 owners, pick up a few of these when they hit shelves in May and retire the 10-round mags to backup duty. For anyone considering a G44, the 15-round capacity makes the value proposition stronger: more trigger time per session at .22 LR ammo costs.
