The Best Suppressor For A 9mm Sig Sauer M17 2024

Sig Sauer made history a few years ago when it was announced that the company would be providing the US military with its new semi-automatic sidearm, the M17.

The M17 is just the third semi-auto pistol to be adopted by US forces. The first, the M1911, was in service for 76 years. Beretta's M9 came next and served faithfully for 32 years. Now it's the M17's turn to prove its worth.

The M17 has a serialized fire control unit, meaning that it has the ability to swap different grip lengths and slide-barrel combinations, which was part of the military's original RFP.

Based on the civilian pistol with the model designation of P320, regular people - and not just the military - can enjoy this new concept in arms technology, whether they're shooting the P320, the M17 Commemorative, or even one of the M17 Surplus pistols.

The only thing better than shooting the latest and greatest pistol technology is shooting it suppressed. So, let's take a look at our top picks for suppressors for the Sig M17.

Suppressor #1: BANISH 45

The BANISH 45 is a modular silencer specifically designed for handguns and pistol caliber carbines in calibers ranging from .45 ACP down to rimfire. Testing shows the BANISH 45 suppresses a 9mm pistol by 36 decibels – far more sound reduction than the competition.

Made of titanium for the ultimate combination of durability and weight reduction, the BANISH 45 is the lightest in its class at a mere 9.6oz in the short configuration of 6.7”. This means that you can add rock-solid performance to your Sig Sauer M17 without adding a ton of weight.

Because of the BANISH 45’s modular design, you can run it with eight or 12 baffles, depending on your specific needs. Ideal for 3-gun or target shooting, the BANISH 45 will help protect the hearing of the shooter and others in a shooting competition and reduce recoil for quicker second shot target acquisition.

User-serviceable from both ends, this suppressor can be easily and quickly disassembled for configuration changes and cleaning. Since it’s made of titanium, you can easily clean the baffles in a tumbler, ultrasonic cleaner, or by hand with a brush and your favorite solvent. Reassembly is just as easy, thanks to the keyed and indexed baffles. This guarantees that each one will be lined up perfectly for optimum performance.

Why We Like It:

  • User-serviceable for cleaning and maintenance
  • Multi-caliber compatibility
  • Modular configuration

The unique design of the BANISH 45 makes it the one suppressor to fit any pistol caliber gun. Simply swap out the pistons (sold separately) and you can attach this suppressor to any multitude of pistols or pistol caliber carbines in your collection. Silencers are a significant investment, so it’s a huge plus to be able to use one can on multiple different firearms and not just your Sig Sauer M17.

  • Weight: 9.6 oz or 11 oz
  • Length: 6.7" or 8.6"
  • Finish: GunKote
  • Materials: Titanium
  • MSRP: $949

Suppressor #2: BANISH 46

You might be wondering why we're putting the BANISH 46 on here right after the BANISH 45. It's just one number different, right? Wrong.

The BANISH 46 is a modular silencer designed for use with a wide assortment of rifle calibers including .338 Lapua up to the mighty .45-70 Government as well as pistol calibers including 10mm and .45ACP. This means it is a great suppressor option for your Sig Sauer M17 and plenty of other guns, too!

Made of titanium and Inconel, the Banish 46 provides the ultimate combination of durability and weight reduction. The BANISH 46 weighs only 16.3 oz in the short configuration of 7.9”, and 20.4 oz in its 10” configuration.

The BANISH 46 is available with a variety of mounting options, including direct thread, a quick-detach muzzle brake attachment, or a Nielsen Device.

Why We Like It:

  • User-serviceable for cleaning and maintenance
  • Multi-caliber compatibility (even more than the BANISH 45)
  • Modular configuration

If you're looking for one suppressor to use on a wide variety of firearms, the BANISH 46 is what you're looking for. You can quickly, easily, and safely transfer this one suppressor between your Sig Sauer M17 semi-auto pistol in 9mm and, say, a Henry X Model lever-action rifle in .45-70 and get equally awesome performance.

BANISH 46 Specs

  • Weight: 16.3 oz or 20.4 oz
  • Length: 7.9" or 10"
  • Finish: GunKote
  • Materials: Titanium

Suppressor #3: Dead Air Wolfman

The Wolfman is the next generation in suppression. Like its Wolf-9SD predecessor, the Wolfman from Dead Air is a modular, multi-caliber suppressor that specializes in sub-gun, light-duty rifle, and pistol use, which means it'll be right at home on your Sig Sauer M17 or a variety of other guns you may own.

Made of fully welded 17-4 PH stainless steel, this provides ultimate levels of strength and durability while still keeping the suppressor as light as possible. It’s the perfect balance of toughness and lightweight, which is very important when it comes to adding a suppressor to a pistol.

The Wolfman is designed for maximum muzzle suppression while also maximizing at-ear performance for the shooter by utilizing a large internal volume and generous blast chamber.

The Wolfman ships with a 1/2x28 direct thread mount and features a wipe-compatible front cap (tool included). Wipes are user-replaceable with commonly available rubber washer sizes.

Why We Like It:

  • Compatible with wipes for extra decibel reduction
  • Good balance between weight and strength
  • Multi-caliber compatibility

Because of its modularity, the Wolfman provides ultimate sound suppression in its full-length configuration while still providing exceptional performance when set up in the short configuration. As an added bonus, the front cap can contain a user-provided rubber wipe that can drop sound suppression levels even further.

Dead Air Wolfman Specs

  • Weight: 9.8 oz or 14.4 oz
  • Length: 5.13" or 7.5"
  • Finish: Cerakote
  • Materials: Stainless Steel
  • MSRP: $989

Suppressor #4: Ultima 9mm

This is the least expensive option on the list, but don't let the price deceive you. Coastal Gun's Ultima 9mm can is a high-quality suppressor constructed of aluminum and stainless steel. This suppressor is outfitted with Coastal Gun's Recoil Attenuation Device (or R.A.D.) mount, meaning that it is designed so that the Ultima will function on semi-auto pistols like the Sig Sauer M17.

You want a suppressor to be as quiet as possible from the first shot to the last, and the Ultima was designed to do just that. It can be shot wet to assist in further reduction of first-round pop.

Ensuring that a can is properly fit to the barrel is essential for safe and effective performance. The Ultima 9mm has built-in knurling on the tube at the mounting end to help you get some extra purchase on the unit to ensure that it is attached securely.

Ultima 9mm

Why We Like It:

  • Affordable, but not "cheap"
  • Can be shot wet to reduce first-round pop
  • Durable anodized finish

If money is a concern, the Ultima 9mm is the most affordable suppressor on this list, but don't mistake "less money" for "cheap." This is a quality suppressor that won't break the bank.

Ultima 9mm Specs

  • Weight: 10.4 oz
  • Length: 9.5"
  • Finish: Anodized
  • Materials: Aluminum and Stainless Steel
  • MSRP: $550
