ISSC M 22 .22 Pistol — As Close as You’ll Get to Glock .22LR

ISSC M22 pistol with the hammer cocked back

The Austrian ISSC M22 self-loading pistol is a fun gun that resembles the world’s most popular police pistol, the Glock. The pistol is affordable at little more than the price of a .22 conversion unit for the Glock pistol and has good features including a Lothar Walther barrel. While it looks like the double action only Glock, the ISSC-Austria M22 is a single-action pistol.

The M22 seems well made.

The M22 is a straight blowback similar to the Ruger Standard Model or Browning Buckmark. The magazine holds 10 rounds of .22 Long Rifle ammunition. The pistol looks and feels like the Glock with a slightly less severe grip angle. The grips are nicely pebbled and provide good abrasion and adhesion when firing.

The sights are also similar to the Glock’s white outline rear notch sight. The rear sight is adjustable for windage. The pistol features an ambidextrous decocker/manual safety. When the pistol is cocked, the safety is used to decock the hammer. The hammer safely falls as the safety has rotated to block the firing pin. When the safety is rotated to fire, the hammer must be cocked to begin firing.

As the pistol fires, the slide recoils and cocks the hammer. The safety cannot be applied with the hammer cocked; it always decocks the hammer. There is also a firing pin block or drop safety, and a lever that is inset in the trigger will not allow the trigger to move if the lever isn’t pressed. The pistol will not fire unless the magazine is seated.

Unlocking the action on the ISSC M22 pistol
A tiny screw in the trigger guard is turned to lock the action.

An additional safety feature is incorporated into the trigger. A screw is turned that properly aligns in either the fire or safe mode. The safe mode locks the trigger. The pistol is long on safety features, and none of them are obtrusive or limit shooting. The trigger action breaks at 5.7 pounds according to the Lyman digital trigger pull gauge.

Cocking grooves are plentiful with five forward and four in the traditional rear position. The ejection port is spacious. The pistol features a loaded chamber indicator that provides both visual and tactile notification. The fixed barrel is manufactured by Lothar Walther and appears to be well fitted and finished.

A note of caution is in order here. The recoil spring fits only one way, so be certain to keep it properly positioned or there may be malfunctions. The pistol features a Weaver mount for a combat light. This should make for good practice sessions with the light mounted.

Disassembly isn’t difficult.

Disassembly isn’t terribly different from many small caliber pistols. While the pistol uses Glock-type takedown levers, the ISSC pistol features a fixed barrel, so the takedown is different. The levers are pressed down with the safety applied, and the slide is pulled to the rear and off the top of the barrel.

It is simple enough and does not require much effort. The pistol needs lubrication to properly function, so be certain to lube the piece well before firing. The pistol, like most quality .22s, should be cleaned every 300 rounds. As for reliability, I have found the ISSC M22 to be similar in that regard to the SIG Mosquito.

With loads it likes, it is very reliable, but otherwise not. ISSC recommends a 200-round break in with the specified loads. Recommended loads are but two, the CCI Blazer and CCI Mini Mag. Both are quality, high-velocity loads that will give good service. As it turned out, my rather large ammo larder was empty of either load.


Caliber .22LR
Capacity 10 + 1
Barrel 4 inches
Weight 21.5 ounces

I used the fast CCI Velocitor and the Winchester Super X hollowpoint. Each proved reliable while firing 100 cartridges of each load. There were no failures to feed, chamber, fire, or eject.

This is a fun gun! If I had had a stack of magazines, I would have loaded them and simply blazed away at steel plates to my heart’s content. The pistol is a great plinker, and a training gun well suited to indoctrinating young shooters into handgun shooting. While Glock shooters may find it a fine understudy, I am a certain those needing a good .22 caliber pistol will find the M22 useful as well.

I enjoyed firing the pistol in combat shooting drills and also in bullseye accuracy. The sights are well designed and make for good practical accuracy. They are not bullseye sights, they are Glock-type combat sights.

Firing from a solid bench rest over the sandbag, I fired several five-shot groups. At 15 yards, the pistol averaged two-inch groups. The pistol is well made and should be reliable with proper lubrication, regular cleaning, and attention to its load preferences.

What do you think of the ISSC M22 as a practice gun for a Glock? Do you use a .22LR for training? Share your answers in the comment section.

  1. I think a better option is to make your own. You can now buy stripped or complete factory glock frames…I have seen complete frames as low as $125, add an Advantage Arms conversion and now you have as close to factory 22 lr Glock as you can get. Total=335 for a complete pistol. Added plus you can find AA mags for cheap…$13 for 10 rnd. Mine has been as reliable as my Ruger 22/45.

  2. Go with a Glock 26 or their single stack 9mm.You’ll get more stopping power,and they are compact.
    I have the opposite problem:large left hand.

  3. I absolutely love this little weapon! I bought one years a go to use for my Concealed Carry classes.
    Most females want to shoot semi autos but don’t have big enough hands to carry full size Glocks… This pistol is almost identical to the Glock 19. I saw one of these and immediately liked the extra “safeties” this weapon has. Most females love the light recoil of the .22 and it allows me to train them without the “flinch” i get from the 9mm. This also builds confidence on the shooters part to allow me to put them on the Glock 19 without too many changes! Then they see the recoil is not bad and they go from there! ATI does sell extra mags when they have them. I have bought several just to have loaded and ready.
    Bob Eker…. This pistol needs “hot” ammo to cycle correctly… Check the owner’s manual mine suggested the CCI mini mags for this weapon! Mine functions flawlessly with those in the mag!

    1. Bo Dias, This is what my manual says. Nothing about CCI MM. It claims it shoots all US standard .22lr ammo.


      The M22 pistol is chambered only for the .22 caliber Long Rifle cartridge, standard or high velocity, manufactured to U.S industry standards. Do not attempt to load .22 Long, .22 Short, or any other type .22caliber cartridge into the magazine or into the chamber, even if the cartridge appears to load properly.


  4. I own an M22, and the only problem I have is trying to use American Eagle HV 38 grain. It fails to eject about 4 times per mag. Any other ammo work great. I just don’t shoot AE through it.

  5. I had an ISSC .22 in the copy of the SCAR .308 battle rifle. Same exact feeding/extraction issues, class 3 malfunction every 2-3 shots. Looked cool but total garbage. This company does NOT make anything close to a functioning firearm.

  6. Great, so now their is a company that shoots the smallest -weakest size cartridge, and it shoots out of a plastic gun that’s all the rage. I think people would start buying guns it it was made from hardened dog poo, if it became the new rage.Out of the 5 9mm pistols I own the Glock is my least favorite. And the only reason I own one is because I was helping out a friend that needed money! Go to the gym build up those weak muscles! Plastic for play, METAL FOR MEN.
