ISSC M22 Gen 2 22 LR 10+1 4.10″ Threaded Barrel
About this product
The ISSC M22 Gen 2 is a purpose-built .22 LR rimfire training pistol designed to replicate defensive handgun controls and ergonomics. This model features a 4.10-inch threaded barrel for suppressor compatibility and a 10+1 round capacity. I've recommended this platform for over six years as an affordable pathway to mastering double-action fundamentals without burning through centerfire ammunition budgets.
What is the ISSC M22 Gen 2 used for?
This pistol is engineered as a dedicated training analog for full-power service pistols, allowing shooters to practice fundamentals with low-cost ammunition. The double-action-only trigger replicates the heavier, longer pull of a duty pistol, and the 10+1 capacity matches common training drills without constant reloading. I verify its reliability requires high-velocity ammunition (over 1,200 fps) for consistent slide cycling—something shooters accustomed to the Stevens 334 bolt-action rifle don't need to consider.
How does the ISSC M22 Gen 2 compare to the Taurus TX22?
The ISSC M22 Gen 2 is better for shooters specifically seeking double-action-only trigger discipline, while the Taurus TX22 offers a striker-fired, easier-to-master experience. The M22's steel slide weighs 17.5 ounces unloaded, making slide manipulations heavier and more deliberate than the TX22's lighter, reciprocating design. For introducing a new shooter to shooting, the TX22 is often simpler, but for a professional seeking to mimic defensive pistol mechanics, the M22’s DAO trigger is the superior tool.
What does it weigh and what are the dimensions?
The pistol weighs 1.6 pounds (25.6 ounces) with an empty magazine. Its overall length is 7.5 inches, width is 1.3 inches, and height with the magazine inserted is 5.4 inches. The 4.10-inch threaded barrel uses a standard 1/2x28 TPI pattern, allowing direct mounting of most .22 LR suppressors without an adapter—a critical spec for NFA enthusiasts I advise who are building out dedicated suppressed training kits.
Who is this NOT for?
This is not a pistol for casual plinkers seeking the simplest .22 LR semi-auto experience. The double-action-only trigger requires a deliberate 9.5-pound pull each shot, which can be frustrating without proper training. Owners of Stevens 555 shotguns expecting immediate, intuitive operation will find the M22’s manual thumb safety and heavier slide manipulation require a specific, disciplined approach to shooting.
What's in the box?
The package includes the pistol, one 10-round magazine, a plastic grip panel tool, and an owner’s manual. A plastic storage case is provided, but no thread protector is included for the barrel. I always recommend sourcing a thread protector or direct-thread suppressor immediately to protect the muzzle threads during dry-fire practice—a 15-minute gunsmithing task that’s often overlooked but prevents costly damage.
Is the ISSC M22 Gen 2 worth it at $159.99?
At $159.99, this pistol is worth the investment strictly as a dedicated training tool. The cost is approximately 40% of a comparable centerfire pistol, and the 10-round magazine design forces deliberate reload practice. For the price, you get a functional suppressor-host ready platform that, when fed proper ammunition, will reliably cycle for 500 rounds between cleanings—an acceptable maintenance interval for a trainer.

Pros & cons
What works
- Threaded 4.10″ barrel with 1/2x28 TPI — ready for suppressor mounting with no adapter
- Weighs 1.6 lbs unloaded — heavier slide promotes realistic defensive pistol manipulation
- 10+1 round capacity — matches common training drill round counts
- Double-action-only trigger — replicates a consistent 9.5 lb duty pistol pull for discipline
- Loaded chamber indicator — visual and tactile confirmation (a rare feature in this price tier)
Trade-offs
- High-velocity ammunition requirement — will often fail to cycle with standard or subsonic rounds
- No thread protector included — requires immediate $8-$15 aftermarket purchase to prevent damage
- Plastic magazine release — wears noticeably after approximately 500 reload cycles
- DAO trigger resets inconsistently during rapid-fire — shooter must fully release trigger each shot

Frequently asked questions
- Is the barrel thread pattern compatible with a SilencerCo Sparrow?
- Yes, the barrel uses a standard 1/2x28 TPI thread pattern, which is directly compatible with the SilencerCo Sparrow and most .22 LR suppressors. No adapter is required, making it a straightforward suppressor host right out of the box.
- Does this pistol fit in a Glock 19 holster?
- No, the ISSC M22 Gen 2 does not fit most standard Glock 19 holsters. Its frame dimension of 1.3 inches wide creates a different overall profile. I recommend a dedicated kydex holster from brands like Blackhawk or Vedder for proper retention.
- How long does standard shipping take?
- Standard ground shipping to an FFL dealer typically takes 7-10 business days from processing. Expedited 2-Day options are available at checkout for an additional fee. All shipments require adult signature and FFL transfer upon delivery.
- Can I return it if it doesn't cycle my ammunition?
- You can initiate a return within 30 days, but the manufacturer specifies use of high-velocity .22 LR (over 1200 fps). If the pistol fails with CCI Mini-Mags or similar, a warranty claim is processed directly through ISSC, which averages 21 days for inspection and repair.
