Description
The ISSC M22 Gen 2 22 LR 10+1 4.10″ Threaded Barrel is a rimfire training pistol built to mirror the controls of a full-size defensive handgun while letting you shoot affordable .22 LR ammo. It comes from ISSC, an Austrian firearms manufacturer known for practical, reliable designs. The double-action-only trigger, threaded barrel, and accessory rail make this a solid choice for low-cost practice without giving up the feel of a centerfire gun.

Key Features
- Threaded Barrel (4.10″) — Lets you attach a suppressor or compensator for quieter training or reduced muzzle rise, especially useful for new shooters getting comfortable with recoil.
- Front and Rear Serrated Steel Slide — Gives you a positive grip for press checks or clearing malfunctions, even with sweaty or gloved hands.
- Double-Action-Only Trigger — Provides a consistent trigger pull every time, simplifying training for new gun owners who don’t want to learn manual safety disengagement.
- Manual Thumb Safety — Adds a layer of security for those who prefer to carry or store with the safety engaged, common on many defensive pistols.
- Picatinny Accessory Rail — Accepts lights or lasers for low-light training drills, helping you practice with the same gear you’d use on a centerfire handgun.
Who It’s For
This pistol is for the new gun owner who wants to train often without breaking the bank on ammo. It’s also a great fit for anyone looking to practice defensive-handgun fundamentals — grip, sight alignment, trigger control — using a gun that handles like a larger-caliber pistol. If you’re a family buying your first firearm for home defense or range practice, the M22 Gen 2 gives you a low-recoil, reliable platform to build confidence.
Pros and Cons
- Pro: Extremely affordable to shoot — .22 LR ammo costs a fraction of 9mm, so you can run hundreds of rounds per session without wallet shock.
- Pro: The threaded barrel comes standard, saving you the cost of buying an aftermarket barrel if you plan to suppress.
- Con: The double-action-only trigger is heavier than a single-action or striker-fired trigger, which takes some getting used to for precise shots. This is by design for training, but it’s worth noting if you prefer a lighter pull.

| MSRP (approx) | $159.72 | $399 | $419 |
The ISSC M22 Gen 2 undercuts both competitors on price by a wide margin while still offering a threaded barrel and a full-size grip profile. The Walther P22Q and Smith & Wesson M&P22 Compact are lighter and have more traditional trigger systems, but the M22’s heavier trigger actually helps new shooters build finger strength and discipline — a hidden training benefit. According to ISSC specs, the M22 Gen 2 is designed to run reliably with high-velocity .22 LR, so stick with CCI Mini-Mag or similar for best results.
Frequently Asked Questions
What kind of ammunition does the ISSC M22 Gen 2 require?
Per ISSC, the M22 Gen 2 is built to function reliably with high-velocity .22 LR ammunition. Standard-velocity or subsonic loads may not cycle the slide properly, so stick with brands like CCI Mini-Mag, Federal AutoMatch, or Remington Golden Bullet. This is common for .22 LR semi-autos, and using the right ammo ensures consistent feeding and ejection.
Can I mount a red dot sight on this pistol?
The M22 Gen 2 does not come with an optics-ready slide, so you cannot directly mount a red dot without having the slide milled by a gunsmith. However, the Picatinny rail under the barrel lets you attach a laser for aiming assistance, which is a popular alternative for training. If you want a red dot, consider a .22 LR pistol like the Taurus TX22 Competition or Ruger Mark IV Tactical, which have factory optics cuts.
Is the ISSC M22 Gen 2 suitable for left-handed shooters?
The manual thumb safety is located on the left side of the frame, which is standard for right-handed shooters. Left-handed users can still operate the safety with their trigger finger, but it’s not as convenient. The magazine release is also on the left side. This is a common trade-off at this price point, and many left-handed shooters adapt quickly with practice.
How does the double-action-only trigger affect accuracy?
The DAO trigger has a longer, heavier pull — typically around 8-10 pounds — which can initially reduce precision for new shooters. However, it also eliminates the need to manually cock the hammer or disengage a safety before each shot, simplifying the manual of arms. With practice, the consistent pull weight helps build muscle memory for smooth trigger control that transfers to other DAO or striker-fired pistols.
