Glock Confirms G44 15-Round Magazine
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, introduced in late 2019 on the G19 frame footprint with a hybrid steel/polymer slide, and it had shipped exclusively with 10-round magazines from launch until this release.
The magazine shipped on schedule and is in stock now at major Glock dealers. Primary Arms sells the factory G44 15-round magazine for $27.99 with same-day shipping, and GunMagWarehouse and GlockStore also list it, putting street pricing right around $28. Glock's release confirms a polymer double-stack design with an integrated load-assist, and the G44 now ships from the factory with the 15-round magazine as standard.
Why 15 Rounds Matters for .22 LR Training
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 Glock 19, 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."

Bottom Line
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 at around $28 each now that they are on shelves 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.
Most G44 buyers already own or are shopping for the centerfire G19 it trains for. See our best 9mm pistols ranking for how the G19 stacks up against other compacts before you build out a full rimfire-plus-centerfire training pair.
