Introduction
The JK Armament 105 CCX is a micro 9 mm pistol suppressor built for people who actually carry their pistol. It trades a little absolute suppression for an extremely compact, featherweight form factor that keeps the gun balanced and holster-friendly—so you’ll use it more, not less.
JK Numbering — How “105” Works
JK names its families by outer diameter. The first three digits are the OD in inches ×100: 105 → 1.05" OD (micro), 155 → 1.55" OD (mid-size), 195 → 1.95" OD (large-format/shotgun). The letters that follow indicate the role; CCX is the carry-centric 9 mm model in the 105 family.
Where the CCX Fits
Think of the CCX as a “quiet-enough to matter” solution for concealed carry, low-profile range work, and training inside realistic round counts. If your top priority is maximum quiet for extended range sessions, step up to larger K/full-size cans. If you prioritize minimal bulk, pocketable diameter, and natural handling on a small pistol, the CCX is the right tool.
Build, Size & Mounting
- Material: 7075 billet aluminum (hard-anodized)
- Weight (as tested): ~2.5 oz
- Length (as tested): 4.6"
- Diameter: 1.05" OD — clears most open-bottom holsters
- Mount: Direct-thread (pistol threads as tested)
- Product code (row): EA04
The extreme low mass means many tilting-barrel hosts will cycle without a booster (host-dependent—always verify on your pistol).
How We Meter & Why It Matters
We publish two positions for pistols:
- ML (Muzzle): A 1 m muzzle position that tracks raw system output at the gun.
- SE (Shooter’s Ear): At the shooter’s dominant ear—this is what you feel and hear.
We also include Δ dB (“delta”) which is the reduction versus our unsuppressed baseline on the same gun and ammo. As a rule of thumb, a 10 dB reduction is roughly perceived as about half as loud to the ear, even though every shooter and environment is a bit different.
Measured Results (9 mm)
- ML (Muzzle)
- 152.2 dB (Δ ≈ −11.0 dB)
- SE (Shooter’s Ear)
- 145.5 dB (Δ −10.0 dB)
These deltas line up with the CCX’s design intent: about half the perceived loudness vs. unsuppressed while keeping a genuine carry profile. In our broader pistol table it faired well for its size, though several larger K-length 9 mm cans posted stronger numbers—at the cost of more length, weight, and often a booster.
Tone, Gas & Shootability
The CCX produces a clean, quick tone that doesn’t overwhelm the shooter with back-pressure. The small diameter keeps sight picture natural and reduces “front-heavy” feel on compact pistols. The direct-thread mount avoids piston bounce and keeps POI behavior consistent when properly installed.
Reliability & Setup Tips
- Thread prep: Clean, lightly oiled threads; seat fully and hand-snug, then verify alignment.
- Function check: Test your specific pistol for full lock-back and reliable cycling with your duty/defense ammo.
- Wet vs. dry: If your manual allows, a small amount of approved ablative can improve early-string tone; expect diminishing returns as it burns off.
- Holster fit: The 1.05" OD typically clears open-bottom holsters; confirm retention and draw stroke before carry.
Maintenance & Longevity
Aluminum saves weight but benefits from sensible care: avoid harsh chemical dips intended for steel, don’t over-torque, and keep lead/carbon under control with regular cleaning. Modular micro cans reward a simple schedule—clean more often, a little at a time.
Pros
- True micro profile (1.05" OD) with realistic carry weight
- Notably quieter than bare muzzle—~10 dB Δ at the ear in our data
- Direct-thread simplicity and consistent POI behavior
- User-serviceable; straightforward upkeep
Cons
- Less absolute suppression than larger K/full-size 9 mm cans
- Aluminum construction requires appropriate solvents and cleaning habits
Who Should Choose the 105 CCX?
Carry-minded shooters who value a pistol that still handles like a pistol. If your priorities are small footprint, low mass, and a real-world drop in loudness, the CCX makes sense. If your priority is “as quiet as possible for long strings,” you’ll want to step up in size.

Bottom Line
The JK Armament 105 CCX nails its mission: a carry-first 9 mm suppressor that stays compact and light enough to live on the gun, yet still delivers a meaningful reduction in report. If you’ll actually carry it, you’ll actually use it—this is where the CCX shines.
