Key Specifications

Performance & Engineering

The Erector 9’s modular design lets you add or remove baffles to achieve the exact length and performance profile your 9mm platform requires. Whether you’re running a compact EDC pistol or a dedicated PCC (pistol-caliber carbine), the Erector 9 adapts to your setup. The stainless steel construction provides superior durability and thermal stability, essential for sustained-fire applications where heat management matters.

Q’s engineering philosophy prioritizes both sound suppression and reliability. The ~28 dB reduction transforms 9mm’s signature bark into a controllable report, protecting shooter hearing and reducing muzzle report signature. The modular mount system eliminates guesswork—you build exactly what you need, making the Erector 9 a smart investment for shooters who run multiple 9mm hosts.
