Which Modular Pistol Suppressor Should You Run?

Whether you’re out on patrol or plinking away at sarsaparilla bottles, the Mojave series from Dead Air gives you the versatility to tackle whatever comes your way with the Dead Air Mojave 9 and Dead Air Mojave 45. Dead Air’s patent-pending Triskelion gas system combines strong suppression with noticeably lower back pressure, while the modular body lets you swap between short and long configurations for the exact balance of size, weight, and sound you want.

But choosing your model isn’t as simple as whether or not you’re building for a 9mm or .45 cal barrel. The Mojave 9 is the lighter, slimmer 9mm-optimized choice, but the Mojave 45 adds wider big-bore coverage from everything from 9mm to 45 ACP. Let’s saddle up together and get you figured on which high-performance model is the best pick for you.

Build and Gas System

Triskelion Baffles and Low Back Pressure

The core of both models is Dead Air’s Triskelion baffle geometry. This innovative design channels expanding gases forward instead of back into the action, resulting in effective suppression while minimizing blowback for cleaner optics and improved shooter comfort. Direct metal laser sintering (DMLS) additive manufacturing makes these complex baffles possible while keeping weight low, achieving previously impossible performance.

Material Differences

The Mojave 9 blends titanium, aluminum, and stainless steel to balance low weight and excellent corrosion resistance. The Mojave 45 goes all-in on a titanium body, its thicker construction allowing it to handle higher heat from big-bore calibers while remaining lightweight.


Size, Weight, and Handling

Short Mode vs Long Mode

Both suppressors boast short and long configurations, allowing users to quickly optimize between concealed carry, fast dot tracking, and easier holster fit or better noise reduction. The Mojave 9’s 1.405 in diameter offers slightly better sight clearance for factory pistol sights, while Mojave 45’s 1.48 in tube still stays below the 1.5 in threshold that typically blocks most tall irons.

Pistols vs PCCs

Both models easily fit on tilting-barrel pistols like Glock 19, SIG P320, and other threaded-barrel 9mm or .45 Auto handguns. For fixed-barrel platforms like the SIG MPX, CZ Scorpion, or 9mm ARs, users can simply replace the included booster spring with a fixed-barrel spacer. Both models accept Dead Air P-Series adapters, allowing 3-lug or direct-thread mounting on a wide range of carbines.

Caliber Coverage and Use Cases

Mojave 9: 9mm to 350 Legend

Ideal as a dedicated 9mm suppressor for pistols and PCCs, the Mojave 9 keeps weight to a minimum and maintains a slim profile. It is rated for full-auto fire for 9mm to subsonic 300 BLK with full-auto fire, and can handle supersonic 300 BLK or 350 Legend in semi-auto.

Mojave 45: The Whole Spectrum

One of the strongest advantages of pistol calibers is their interchangeability between handguns and long-guns using the same cartridge. For shooters who want to quickly swap a single suppressor between a handgun and a PCC or rifle, the Mojave 45 is a fantastic choice. The sheer coverage provided by the Mojave 45 across 300 BLK supersonic, 350 Legend, 400 Legend subsonic, and even 450 Bushmaster subsonic loads makes this one of the most versatile pistol suppressors on the market.


Mounting and Day-One Setup

Each Mojave ships with a PB500 booster assembly and an appropriately threaded piston: 1/2×28 for the Mojave 9 and .578×28 for the Mojave 45. For fixed-barrel carbines or sub-guns, install a Dead Air fixed-barrel spacer or choose from the P-Series adapter line. Before firing, verify alignment with a rod, apply the correct torque, and test with your preferred carry or duty ammunition.


Sound, Tone, and Gas

The Mojave series’ Triskelion baffle design helps maintain reliable cycling while reducing gas blowback and providing maximum sound suppression possible. Perceived tone varies by host, barrel length, and ammunition, so check each product page for the latest meter data or third-party sound tests if you need exact numbers.


What’s in the Box and Warranty

Each package includes the suppressor, the appropriate piston, and the PB500 booster assembly. Finish options include Black or FDE high-temperature Cerakote, with an additional satin bead-blast option for the Mojave 9.

Dead Air backs both models with a limited lifetime warranty.

Which Dead Air Mojave Should You Buy?

Choose the Mojave 9 if:

  • You want the lightest package and smallest diameter for everyday pistol carry or PCC training.
  • You want a modular but high-performing 9mm option that can also function with 300 BLK.

Choose the Mojave 45 if:

  • You want the most versatile range possible or are building for .45 ACP.
  • You want maximum heat resistance to handle aggressive firing schedules.

Either way you get:

  • Short and long modularity
  • The Triskelion low-back-pressure system
  • No barrel-length restrictions
  • Silencer Shop’s streamlined eForms process.

Installation and Tuning Tips

  • Match the piston thread to your barrel (1/2×28 for most 9mm, .578×28 for .45 Auto).
  • Use a fixed-barrel spacer for PCCs or other non-tilting barrels.
  • Verify alignment before live fire.
  • Run a few magazines of your defensive or competition load to confirm reliable cycling.

Alternatives to Consider

  • Ventum 762 – a HUB-mount suppressor with a serviceable core for those who prefer a more traditional design.
  • FLOW Range 36 Ti – an ultra-light multi-caliber Flow-Through model that ships with a HUB QD adapter for broader mounting flexibility.
