Review: Glock M44


I have been using the .22 caliber cartridge for more than half a century.

There have been times when I have been involved in training, police work, and competition and left the .22 by the wayside.

I think my shooting efforts were impoverished by this expedient. A .22 caliber pistol is a great trainer and an all-around good target gun.

The .22 is a fine small-game pistol as well. A lot of folks use handguns for single-chore training, personal defense or home defense.

A quality handgun is more versatile and may open up more avenues for fun and recreation while offering a degree of protection as well.

The .22 Long Rifle is a useful cartridge—accurate, powerful enough for target practice and small game, and affordable.

While there are .22 caliber conversion units available for a number of service handguns, I find having a second handgun in .22 Long Rifle more desirable.

Until very recently, a true .22 caliber understudy for the GLOCK centerfire handguns wasn’t available. We now have the GLOCK M44 .22.

The GLOCK M44 .22, bottom, is similar in size to the GLOCK 19 9mm, top.

GLOCK M44 vs. GLOCK 19

The GLOCK 44 is designed to mimic the size, operation, and handling of the GLOCK 19 9mm.

It will be useful for training if you own other GLOCK centerfire handguns. (Or any other centerfire handgun.)

I agree the GLOCK 19 size makes the most sense for this effort. GLOCK shooters are the target audience for this handgun and many of us will have to have the new GLOCK.

But the pistol is also suitable for beginners who have never owned a handgun or for shooters that own any type of handgun.

A .22 is like that. The most useful role is as a rimfire trainer. The modest price makes it as affordable as most .22 caliber conversions.

The GLOCK 44 is dimensionally identical to the GLOCK 19, but much lighter due to a polymer and metal slide.

A heavy steel slide could not operate with the modest recoil of a .22 caliber cartridge.

The lightweight GLOCK 44 slide gets enough kick from a . 22 Long Rifle cartridge to operate with reliability.

Due to differences in the locking block and other parts you cannot place a GLOCK 44 slide on a GLOCK 19 and convert it to .22 caliber operation.

The sights and trigger operation are the same as the GLOCK 19. The trigger breaks at 5.8 pounds, the same as a Generation 4 GLOCK 19 on hand.

GLOCK pistols of late production seem slightly heavier than the 5.5-pound GLOCK standard we once experienced.

The front post and rear notch sight feature the standard GLOCK white outline. The rear sight is fully adjustable, a nice touch on an affordable .22.

GLOCK M44 Features and Specs

The overall length of the GLOCK 44 is 7.28 inches. The barrel length is 4.02 inches. The pistol fits GLOCK holsters I had on hand, no worries.

Frame inserts are provided of the same type as supplied with other GLOCK handguns to aid hand fit and the pistol features a rail for mounting combat lights.

The GLOCK 44 features a GLOCK Marksman barrel with fluted chamber. The GLOCK 44 may be dry fired without harming the firing pin.

The slide lock, magazine release and takedown are standard GLOCK. The big difference in handling is the weight.

The GLOCK 44 weighs just over 14.5 ounces, nine ounces less than the GLOCK 19. The GLOCK 44 uses a single column style 10-shot magazine.

A high-capacity magazine is very difficult to convince to feed with the rimmed .22 Long Rifle cartridge.

The 10-shot magazine features a nicely located tab on the follower that makes loading easy.

Depress the tab and load one round at a time to properly stack the ammo in the magazine.

The barrel is separate from the frame, not fixed like most .22 rimfire barrels. The frame is a Generation 4-type with finger grooves.

Ammo Performance

Most .22 Long Rifle self loaders are designed to function only with high-velocity ammunition.

As a rule, this ammunition is less expensive than the less common standard-velocity loads, so there is no point in using the less zippy loads for general target shooting and training.

The GLOCK was tested with more than 100 types of ammunition for reliability, GLOCK tells us. At this point, I am just over seven bricks or 3,500 rounds of ammunition.

The GLOCK 44 isn’t as reliable as most GLOCK pistols, simply due to the nature of rimfire ammunition. It is more reliable than most .22 caliber self loaders.

It functions 100 percent with CCI Mini Mag ammunition, even when dirty from firing 300 rounds without cleaning.

Remington Thunderbolt, Winchester Super-X, and Fiocchi high-velocity loads also did well.

When the GLOCK 44 is clean and well-lubricated, it will function to a point with subsonic loads, but may not lock the slide open on the last shot due to decreased momentum.

If the GLOCK 44 has a few hundred rounds through it and increased powder ash, there were instances of a spent case failing to fully eject and getting caught between the slide and the barrel.

A clean GLOCK 44 with high-velocity ammunition will usually run 100 percent for 300-400 rounds, exceptional for a .22 caliber handgun.

Some loads do not run as well.

.22 ammunition isn’t that expensive, so you can test a variety of loads or simply stick with proven loads from the major makers.

The pistol is comfortable to fire, no surprises there.

It offers real utility in training. As for accuracy, the piece will put five rounds of Remington Thunderbolt into 2-2.5 inches from a solid benchrest at 25 yards.

Other loads offer similar accuracy. The GLOCK M44 is accurate enough for small game hunting at modest range.

GLOCK M44 - Field Stripping

The GLOCK M44 is a fine recreational handgun with much to recommend. For more serious personal defense training, the GLOCK 44 .22 excels.

You can get in a lot of trigger time for very little expense.

You will also need to learn recoil control by firing your 9mm in practice, but as far as sight picture, sight alignment and trigger press you can learn well with the GLOCK 44.

This GLOCK may be the best-suited as a first GLOCK and for others, it is the must-have GLOCK to add to the stack in the gun safe.

  1. I like the G44, but it has had some teething problems come up as most new guns do as the get out into the general public, while I’m going to give them some time to get the kinks out, I will eventually add one to the gun safe. I too was not totally happy with
    One of the aftermarket kits for glock.
    Ended up giving it away. The expensive Beretta OEM .22 Conversion kit I have for my M9 works well functional wise, but it is no match .22 to say the least! Most dedicated.22 pistols will shoot rings around it.

  2. I have been looking at Glock for a while now and this looks like something i might be interested in. Been on the fence for a while now bout getting a 9mm carry and this looks like a good trainer to keep in practuce without breaking the bank.

  3. The good thing is that it is a Glock, and training on one is the same as training on another. The .22 caliber makes this economical. The bad news is that this is a Glock, and it is not an exceptional gun to hone your shooting skills.
    With guns, there is no “one size fits all.” If you buy a 9 mm Glock, you need to practice with it, and not buy two, one for defense, and one for practice. You can learn to shoot on other guns that employ accuracy and safety, absent in the Glock.
    And, if you are only going to own one gun, I would tell you to buy a revolver. I think a pistol, for a novice, can be confusing, while with a revolver all you have to remember to do is point and shoot. A pistol has built-in flaws, and if you get a misfire, you have to recognize it immediately. (Have you ever watched somebody thinking their gun was in battery when they actually had a stovepipe sticking out). I have.

  4. I purchased my G44 right after it first became available in January, and I’m extremely pleased with it thus far. Prior to purchasing the G44 I was running a TSG-22 conversion on my Gen 3 G19. That was okay, but not ideal, and the G44 has proven to be a superb investment even though I still have the TSG conversion.

    My G44 has fired somewhere over 2,000 rounds (perhaps now closing on 3,000+), using a variety of ammo but mostly Remington Golden Bullet 36gr HP from their 525-round value packs. The Remington GB seems very sooty, but I often shoot 250+ rounds in a single session and can easily go 400-500 rounds between cleanings without noticeable malfunctions. Most of the malfunctions I’ve experienced thus far are actually just failure-to-fire, which appears to be caused by poor priming in the ammo itself, not any fault of the Glock. l have had occasional stovepipes, but they’re not frequent: perhaps just one every 100+ rounds or so…and some of those stovepipes could also be ammo-related as I’ve observed occasional Rem. GB rounds to be notably less peppy than average. I have heard reports of some G44s cracking, but mine is holding up great so far.

    I’ve coached a few NRA Women On Target events in the past, and I enjoy introducing new/less-experienced shooters to handguns. The G44 is perfect for that role, as an obvious first step leading to G17/G19, and I have a great time just shooting it myself as well! I’m not necessarily a Glock fanatic, but the vast majority of my training has been with Glocks and they always just work for me…so that’s what I shoot. The G44 may not have received all the fanfare Glock anticipated when they introduced it, however I am perfectly happy with mine and would absolutely recommend it. Hope you find this helpful.

  5. As a 30 year veteran of Law Enforcement, I carried a Glock 21 for approximately 20 years of that time. I have retired, but still carry a Glock 26 or 43 most of the time. So, when the Glock 44 showed up at my favorite gun shop I had to buy it.

    I have found it to be an excellent training gun. The function, trigger pull, grip and sighting is like shooting my other Glocks, with less recoil of course. I mainly shoot CCI rounds so have not had any problems with feeding or ejection. Overall, this is a great pistol to add to anyone’s collection.

  6. The G44 does NOT have finger grooves like a Gen 4, it is Gen 5 in profile, and with multiple backstrap options it makes for a versatile training platform. Mine has almost 5,000 rounds of multiple maker / loadings through it, only fumbling ejection when dirty and using standard velocity ammo.

  7. Though I likely do not have the experience and technical know-how of most, I strongly believe in the use of replica .22’s in training. When Department budgets are lean, using this (if Glocks are the issued sidearm) and a .22 M4, trigger control, sight alignment and muscle memory drills are still highly beneficial for pennies on the dollar. This model was a long time coming. My Adv.Arms Glock conversion did not hold up long and was quite temperamental. As an instructor, introducing a new shooter to firearms, .22 is the avenue to non-threatening, enjoyable and affordable range time…some graduate beyond, others prefer to remain. The Glock 44 has a great tactile feel to it…and puts a smile on your face shooting it. However, I do wish it was in the price range of Taurus’ .22 offering.

  8. I agree that the G44 could be a great first Glock. but I’d prefer a Glock OEM conversion unit. My aftermarket kit was disappointing, short-stroking several times per magazine with all the ammo I tried (even the brand that the manufacturer didn’t recommend because it’s supposedly too hot).

    A reliable factory Glock kit would be great you already own another Glock. They’re so simple to field strip / swap (quicker than loading a mag, and you’re going to want to disassemble the fouling-prone .22 every time anyway) that avoiding it isn’t worth the cost and paperwork for an extra receiver, PLUS duplicates (to maintain realistic training) of any preferred upgrades such as trigger, extended controls, light etc. – some of which may not even work with the G44.
