Glock 44: Perfection In .22 LR?

Three years in the making, the new Glock 44 finally gets the gunmaker into the .22 LR market. Was it worth the wait?

It’s not a secret that the Glock G19 is one of the most popular handguns in America. Developing a Glock chambered in .22 LR sounds like a no-brainer. It’s been three years in development, but that’s exactly what Glock did. The Glock 44, chambered in .22 Long Rifle, stays true to the Glock design, but it has a few differences to compensate for the no-recoil .22 LR cartridge.

The Glock 44 is a striker-fired, blowback, semi-automatic compact pistol. For most intents and purposes, it’s a Gen5—although Glock doesn’t call it a Gen5. It uses a modified G19 Gen5 frame and a hybrid polymer/steel slide. The barrel is the Glock Marksman Barrel (GMB) and is not a fixed-barrel like most rimfire handguns. The barrel stays straight during the entire cycling of the action.

The underside of the Glock 44 (left) and the G19 Gen5. The barrel-locking lug on the G44 is long and narrow, while the locking lug on the G19 is short and wide. This prevents these slides from being swapped with the other’s frame.

The Glock 44 can be adjusted to various shooter preferences via an ambidextrous slide stop lever, reversible mag catch and four interchangeable back straps (two beavertail and two standard). It comes with two 10-round magazines, and the polymer rear sight is adjustable for windage and elevation.

The entire Glock 44 is about 10 ounces lighter than the G19, and the majority of that weight reduction is the slide. Most .22 handguns have an aluminum slide, but Glock wanted steel; it’s far more durable. But a steel slide would weigh too much for a .22 LR cartridge to cycle reliably. So, Glock designed a steel sub-structure and incorporated polymer—which Glock obviously knows very well.

For friction points, you always want steel on steel and polymer on polymer, because steel on polymer will expedite wear on those parts. The steel sub-structure is what makes contact with the metal slide rails on the frame, so there’s no friction or stress on the polymer portion of the slide. The slide face where the cartridge sits is also steel, as is the nose ring that the barrel goes through.

The slide internals don’t look much different than standard Glock OEM parts, but there are some changes, mostly due to the caliber. The big difference is the GMB. The chamber block is roughly the size of a G19 but has different locking lugs—because it’s not a tilt-barrel—and a ghost hole on top that’s a loaded chamber indicator.

The slide will accept any aftermarket sights designed for the G19. Nevertheless, take note if you go that route, because the dovetail is polymer, and metal sights could cause damage during installation if care is not taken.

If you remove the slide, most noticeable is the locking block, which is polymer instead of metal, as well as the area in the frame where the locking block is located. It’s designed so that a G19 and a G44 can’t swap slides.

The trigger is all Glock. The take-up is slightly spongy, but it has a clean break. Glock lists the pull weight at 5.8 pounds; mine averaged about 5.5. For Glock users who don’t care for Glock factory triggers, the G44 will accept aftermarket triggers designed for the G19 Gen5.

When the Glock 44 was announced, the Internet almost exploded—about half with excitement and about half with hate. A lot of that hate centered on the magazine; in particular, the fact that it’s 10 rounds. But why 10 rounds? Why not 15? Everyone has 10. Some new .22s have more.

The hybrid steel/polymer slide consists of a steel sub-structure that makes contact with the slide and houses the high-friction parts. Polymer is then fused with the steel to complete the slide.

The short answer: Glock wanted more rounds too, but during the nearly 14 million rounds fired during its three years of development, having more than 10 rounds in the magazine didn’t meet expectations for reliability.

Although I’d rather have more rounds, I’m fine with that answer. However, for those of us who want more than 10 rounds, ProMag has a magazine in development for the G44. There‘s no set magazine capacity yet, but it will be at least 14 rounds. Its expected ship date is by March 1, 2020.
Aside from the 10-round capacity, one of the things I like most about the Glock 44 is the magazine. It has the same outer dimensions as the G19 magazine. In fact, they’ll fit into each other’s mag well (although my G44 mag won’t lock securely into the G19 mag well).

Why is this so important? Reloads—especially for training. Most .22 pistols have long, slim magazine tubes that are barely larger than the .22 rounds they hold. If you’re practicing realistic reloads, those suck. They’re slow; it’s hard to hit the slot in the mag well under pressure; and the mag wells jam up if you don’t insert them perfectly straight. Glock did it right with the design of the G44 mags, down to the load-assist lever on both sides.

What the Glock 44 Is Not

The Glock 44 stands out from the crowd for several reasons. Foremost, while a majority of the .22 LR handguns in this category feel like replicas, the G44 is a true Glock. It’s the actual Glock design that we know, and it feels like a Glock. More importantly, it shoots like a Glock. Same Glock feel, same Glock trigger, same Glock controls, same Glock maintenance/disassembly, same Glock … well, you get it: It’s a Glock.

Range Time

I know Glock’s goal for the Glock 44 is to shoot everything reliably. But, in reality, .22 ammunition has a very large variation in performance. Glock tested the G44, firing more than 14 million rounds of more than 120 makes of ammo to make sure it could reliably shoot anything. So, reliability was also my focus. I fired 1,500 rounds using 18 different loads.

The locking lugs on the G19 (top/back) are designed for the barrel block to tilt down during the cycling of the slide. The G44 (bottom/front) doesn’t tilt, so the locking lug just keeps it in place.

The Glock 44 I tested just did not like four of the 18 loads I used, which accounted for 350 rounds. It was obvious that it was an issue with the ammo, because almost every time I had a malfunction, it was preceded by a weak-sounding discharge, and the slide either barely cycled or had a weak cycle—often so weak that the spent case barely made it out of the ejection port. Twice, the discharge was so weak that I was convinced it was a squib load, and I disassembled the gun and checked the barrel (I did lubricate the slide before testing, and I added two drops of lubrication after about 500 rounds).

For the rest of the 1,150 rounds fired from 14 different loads, there were 18 malfunctions, seven of which were also due to cartridges with weak powder charges that didn’t completely cycle the slide. Four times, the weak charge wouldn’t cycle the slide enough to extract; seven times, it extracted, but not enough to eject; and there were seven failures to feed (the bullet nose hit outside of chamber and got stuck. These were the seven malfunctions that weren’t related to an underpowered cartridge but were most likely due to carbon buildup. Five happened after). Six times, the slide did not lock back after the last round fired, because the round didn’t have enough power to cycle the slide far enough to lock back. But I don’t count these as failures.

Wrapping it Up

The Glock 44 fills a void in Glock’s lineup that shooters have been asking to have filled for years. It’s not sexy like a carbine or a single-stack 10mm, but it’s probably the thing Glock users have been asking for the longest. The G44 is going to be extremely popular, and Glock will sell a lot of them.
