About
What it is, and why it matters
The SilencerCo Maxim 9 is an American integrally suppressed semi-automatic pistol chambered in 9x19mm Parabellum. Introduced in 2017, it was the first commercially produced handgun designed from the ground up with a built-in suppressor compact enough to be holstered while remaining safe to fire without hearing protection. It uses a fixed barrel with a reciprocating rear slide section riding on dual guide-rod recoil springs and a striker-fired, delayed-blowback action, and feeds from standard Glock 17 magazines. The aluminum suppressor shell houses modular stainless-steel baffles that can be configured in long or short setups to balance sound suppression against overall length.
Named after Hiram Maxim, the inventor credited with the first commercially successful firearm suppressor, the Maxim 9 revived the concept of an integrally suppressed sidearm for the modern civilian and law-enforcement market.
The integral suppressor can be run in a long configuration (~10.75 in) or a shorter configuration (~9.5 in) by removing baffle sections; barrel length stays fixed at roughly 4.38 in regardless. The frame is drilled and tapped to accept a red-dot optic.
