The Dead Air Mojave-9 suppressor with M13.5x1LH piston is a precision muzzle device engineered for shooters running suppressed 9mm handguns with tilting-barrel actions. This piston assembly is the critical interface between your suppressor and host firearm—get the thread pattern right, and you get reliable suppression and cycling; get it wrong, and you get headaches on the range. If your 9mm is threaded with a metric 13.5x1 left-hand pattern, this piston delivers the mechanical compatibility your Mojave-9 needs to function as designed.
Pistons are often overlooked, but they're not an afterthought. The piston's job is to manage backpressure and recoil impulse while keeping the suppressor securely attached to your barrel. A proper fit means consistent performance, repeatable point-of-aim shifts (if any), and confidence that your can won't walk loose. Dead Air's engineering here is focused on reliability in the hands of serious shooters.
This piston is purpose-built for tilting-barrel 9mm platforms—think modern duty and carry pistols, not fixed-barrel designs. If you're running a Glock, M&P, or similar locking-breech platform with M13.5x1LH threading, this is your interface. Compatibility matters: verify your barrel's thread pitch and direction before ordering. The piston accepts a 1/2-28 threaded suppressor on its front end, so confirm your Mojave-9 matches that specification as well.
Whether you're building a suppressed duty gun, a quiet range trainer, or an integrally-suppressed pistol setup, Dead Air's piston engineering reflects the brand's reputation for rigorous tolerance control. This is a wear item in high-round-count suppressors, so understanding when to replace it keeps your can in service for years.

| Model | PB441 |
| Thread Pattern (Barrel) | M13.5x1 Left-Hand (M13.5-1LH) |
| Thread Pattern (Suppressor) | 1/2-28 |
| Caliber | 9mm |
| Platform | Tilting-Barrel Handguns |

M13.5x1LH is a metric left-hand thread specification found on certain 9mm barrels, particularly in some European and specialized designs. Verify your barrel's thread pitch and rotation direction by checking manufacturer specs or consulting the barrel's markings before purchasing this piston. Using the wrong thread pattern will result in a dangerous, non-functional fitment.
This piston is designed to accept a 1/2-28 threaded suppressor on its front end. Confirm your suppressor—whether a Mojave-9 or another Dead Air can—has 1/2-28 male threads before ordering. Piston and can threads must match for safe operation.
No. This piston is engineered specifically for tilting-barrel (locking-breech) handgun actions. Fixed-barrel platforms operate on different mechanical principles and require different suppressor configurations.
The product is the piston assembly itself. Confirm that your Mojave-9 suppressor and barrel threads match this specification (M13.5x1LH on the barrel, 1/2-28 on the suppressor) for complete compatibility.
