Jk Armament 105 CCX

Quick Take

JK Armament’s 105 CCX is a purpose-built concealed-carry 9mm suppressor: a super-light, modular stack that configures from 1.9–4.6″ long and 1.05″ in diameter, weighing just 1.2–2.5 oz. That mass is low enough that most pistols run without a booster,

JK Armament 105 CCX

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−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.

At-a-Glance Specs (as tested)

  • Caliber: 9 mm
  • Length: 4.6"
  • Diameter: 1.05"
  • Weight: ~2.5 oz
  • Material: 7075 billet aluminum, hard-anodized
  • Mount: Direct-thread (pistol threads as tested)
  • Measured: ML 152.2 dB (Δ −11.0), SE 145.5 dB (Δ −10.0)

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.
