SilencerCo Maxim 9

SilencerCo Maxim 9 Details

The SilencerCo Maxim 9 is the world's first integrally suppressed 9mm pistol that is both holsterable and hearing safe with most factory ammunition. Instead of hanging a can off a threaded barrel, SilencerCo engineered the suppressor into the gun from the ground up, so you get quiet performance in a package barely longer than a full-size duty pistol. SilencerCo has discontinued the Maxim 9, so remaining examples move fast; hit Notify Me and we will flag any that land here.

Features & Benefits

• Integral suppression designed in from the start, not bolted on afterward
• Hearing safe with any factory 9mm ammunition, subsonic or supersonic
• Modular length: 10.75 inches in the long configuration, 9.54 inches short
• Feeds from common Glock-pattern magazines
• Holsterable, red-dot ready slide, and 4.38 inch barrel in a 2 lb 7 oz package

Because the Maxim 9 is a pistol and a suppressor in one, it still transfers as an NFA item like any other silencer. If you cannot wait for one to surface, a compact can from our 9mm pistol suppressors on a threaded barrel gets you to the same quiet place, and the rest of the SilencerCo lineup is a good hunting ground. Our best 9mm suppressor guide breaks down the current favorites.

Frequently Asked Questions

Is the SilencerCo Maxim 9 discontinued?

Yes. SilencerCo has moved the Maxim 9 to its legacy products list, and production tapered off in early 2021 as the company shifted its focus to suppressor manufacturing. New units are no longer being made, so availability is limited to remaining or used inventory.

Is the Maxim 9 hearing safe with supersonic ammo?

Yes, in its full-length configuration. Set up full length, the Maxim 9 is hearing safe with all 9mm ammunition, including supersonic and +P+ defensive loads, with muzzle averages of 137.1 dB with 115 gr, 138.3 dB with 124 gr, and 136.3 dB with 147 gr. In the short configuration, it is hearing safe only with subsonic ammunition of 147 gr or heavier.

What magazines does the Maxim 9 use?

The Maxim 9 uses standard Glock 9mm magazines, including Glock 17 round, Glock 30+ round, and aftermarket Glock-pattern 9mm magazines. It shipped with two Magpul PMAG 17 GL9 magazines.

How long is the Maxim 9 in each configuration?

The Maxim 9 measures 10.75 in. in its full-length configuration and 9.54 in. in its short configuration, which is comparable to the overall length of a Glock 17L. It ships in the full-length configuration with all the parts needed to convert it to short.

What are the best alternatives to the Maxim 9 for a suppressed 9mm setup?

The most common alternative is pairing a threaded-barrel 9mm pistol with a compact pistol suppressor. The SilencerCo Omega 9K is a popular choice at just 4.56 in. and 7.3 oz, is full-auto rated, and also handles .300 BLK, though a piston is sold separately for pistol use. Other compact 9mm options include the Rugged Obsidian 9 and the JK 105 CCX 9. A separate pistol and suppressor setup adds some length compared to the Maxim 9, but lets you move the suppressor between hosts and choose any pistol you like.
