The SilencerCo Maxim 9 is an integrally suppressed handgun, which means the suppressor functionality is built directly into the handgun, resulting in a much more compact package than a traditional handgun with a suppressor attached to it.

The SilencerCo Maxim 9 was announced back in April of 2015, but has been in development for nine years. But the wait is over, and it has finally hit the shelves for consumers.

Why integrally suppressed?

Traditional suppressed handguns are long and unwieldy. Taking the suppressor baffles and building them directly into the gun results in a comparatively compact package. This means the SilencerCo Maxim 9 could even be holstered and carried. While it is a bit bulky for most conceal carriers, it is an interesting concept for a home defense pistol or maybe even a duty pistol for law enforcement. This would protect the shooter’s hearing in a defensive encounter when they aren’t wearing hearing protection.

The downside of an integrally suppressed design is that the suppressor cannot be moved between firearms like on a traditional suppressor design. Thanks to the NFA, this means Maxim 9 owners need to pay the $200 tax stamp for a suppressor that can be used by only one firearm.

SilencerCo Maxim 9 sound suppression readings

Standard configuration, industry standard test, with 147gr ball ammo: 125.6 dB – well within hearing safe parameters

Shortened “K” configuration, industry standard test, with 147gr ball ammo: 138.7 dB – technically hearing safe

Shortened “K” configuration, 6″ from the shooter’s ear, with 147gr ball ammo: 135.0 dB – hearing safe

Shortened “K” configuration, 6″ from the shooter’s ear, with 147gr ball ammo: 132.0 dB – hearing safe

This means the SilencerCo Maxim 9 is hearing safe according to the 140 dB standard, even with supersonic standard ammunition.

“Hearing safe” is a widely misunderstood concept. Just because a firearm is hearing safe, doesn’t mean it is safe for extended usage, it simply means that sound rating won’t instantly damage hearing. A lawn mower clocks in at about 90 dB, substantially lower than the ratings of the SilencerCo Maxim 9. Hanging out around a lawnmower from time to time won’t result in hearing damage, but working a lawnmower for hours on end will result in long term hearing damage. The same goes for suppressed firearms. Even though they meat the “hearing safe” level of under 140 dB, doesn’t mean extended shooting sessions won’t damage hearing.

Hearing damage is permanent. Don’t risk your hearing – always wear hearing protection, even when shooting suppressed.
