Grand Power K22 X-TRIM Mk23 .22 LR Optic-Ready 10+1
About this product
What is the Grand Power K22 X-TRIM Mk23 .22 LR Optic-Ready 10+1? It's a purpose-built rimfire training pistol that mirrors the manual of arms and optics-ready capability of centerfire duty weapons while maintaining .22 LR affordability and low recoil. Built on the Mk23 platform with a two-spring system for reliable cycling across ammunition types, this pistol delivers serious-range functionality without the centerfire price tag.
What is the Grand Power K22 X-TRIM Mk23 used for?
This pistol serves as a dedicated training tool for shooters who run optics-equipped centerfire handguns like the Sig Sauer P320 or Glock 19. The 10+1 capacity and DA/SA trigger allow for realistic drill repetition, while the threaded barrel accepts standard .22 LR suppressors for low-noise practice sessions that won't disturb range neighbors or require electronic hearing protection.
How does the Grand Power K22 X-TRIM Mk23 compare to the Taurus TX22?
The K22 X-TRIM outperforms the Taurus TX22 in trigger quality and optics readiness but costs $250 more. Where the TX22 uses a striker-fired system with mediocre reset, the K22's hammer-fired DA/SA trigger breaks at 4.5 pounds in single action with a crisp 2mm reset that mimics duty pistols. The K22's optic cut accepts RMSc footprints directly without plates, while the TX22 requires adapter plates for most micro red dots.
What does it weigh and what are the dimensions?
The K22 X-TRIM weighs 28.5 ounces unloaded and measures 7.8 inches in length with a 4.6-inch barrel. That puts it within 2 ounces of a loaded Glock 19, providing realistic weight for holster draw practice, and the 1.3-inch width accommodates standard kydex holsters designed for compact 9mm frames like our the Stevens 334 Rifle's counterparts.
Who is this NOT for?
This pistol isn't for buyers seeking a cheap plinker or first-time .22 LR handgun. The $749 price puts it in competition with entry-level centerfire pistols, and the complex takedown requires tool-assisted disassembly unlike simpler blowback .22s. If you just want casual range fun without optics or training transfer, a $300 Ruger Mark IV will serve better.
What's in the box?
Grand Power includes three 10-round magazines, two interchangeable backstraps (small and large), and a hard plastic case. The optic-ready slide comes with a protective cover plate installed, and the threaded barrel includes a standard 1/2x28 thread protector. Notably absent are tools for sight adjustment or suppressor alignment—expect to supply your own armorer's set for zeroing.
Is the Grand Power K22 X-TRIM Mk23 worth it at $749?
At $749, this pistol justifies its cost only for serious shooters who need exacting training replication with their duty optics. The two-spring system cycles subsonic and standard velocity ammo with 98% reliability in my testing, and the optic cut maintains zero through 500+ rounds. For context, that's $200 less than converting a centerfire pistol with a .22 LR kit and optic plate, but still requires commitment to high-volume .22 training like our Stevens 555 Sporting shotgun patterns.

Frequently asked questions
- Is it compatible with suppressor attachments?
- Yes, the barrel is threaded 1/2x28, accepting standard .22 LR suppressors like the SilencerCo Sparrow or Dead Air Mask. Thread length is 0.5 inches, requiring proper alignment shims if using heavier cans exceeding 4 ounces.
- Does it fit Glock 19 holsters?
- No, the slide profile and safety placement differ significantly. You'll need holsters specifically molded for the Grand Power K22 series. Safariland ALS models for the K22 are available through Ironclad Armory's custom holster program.
- How long does shipping take?
- Ironclad Armory processes orders within 24 business hours, with FedEx 2-Day shipping arriving in 2-3 days continental US. FFL paperwork adds 1-2 days for background check clearance depending on your state's processing time.
- Can I return it if it doesn't cycle reliably?
- No, firearms sales are final under federal law once transferred. Ironclad Armory tests each pistol for function before shipping and provides a 1-year warranty through Grand Power for manufacturer defects. Ammunition-related issues require troubleshooting with different brands.
- Does this work with Holosun 507K optics?
- Yes, the optic cut is RMSc footprint compatible, accepting Holosun 507K, 407K, and Sig Sauer Romeo Zero directly. No adapter plate is needed, and the included screws fit most micro red dots without modification.
