Four .300 WSM Suppressors You’ll Want This Year 2024

It may be called the .300 Winchester Short Magnum, but don’t let the “short” part of the .300 WSM name fool you. There’s a lot of power packed into this relatively-small cartridge case.

Introduced in 2001, Winchester’s vision for the .300 WSM was to fit as much of a powder charge as possible in the case and position it as close to the primer pocket as possible. The goal they achieved by doing this was a more uniform ignition and similar ballistics to the .300 Win Mag, but while using 8%-10% less powder. Essentially, do more with less, and do it really well.

The resulting .300 WSM cartridge was one that was absolutely perfect for big game animals of all kinds: moose, elk, bear, mule deer, and more.

Of course, the only thing better than hunting with a powerful cartridge like the .300 WSM is to do it suppressed! Thankfully, there are a number of .30-caliber suppressors on the market that are perfect for pairing with a rifle chambered in .300 Winchester Short Magnum, so let’s take a look at the best options!

Suppressor #1: Dead Air Sandman-S

Dead Air’s Sandman suppressors have great reputations and with good reason. The Sandman-S is the “little brother” to the Sandman-L, and while it may be smaller, it still retains all of the performance. Featuring a low blowback design, the Sandman-S is touted for not only its compact construction but also for its impressive noise reduction at the ear. It does a great job at taming the decibels you hear when a shot from a .300 WSM rifle go off.

The Dead Air Sandman-S features a quick-detach mounting system that incorporates an index pattern for ease of mounting and removal. It’s also outfitted with a removable front-end cap, making the Sandman-S extremely user-serviceable, allowing for quick disassembly, cleaning, and fast reassembly.

Why We Like It:

  • QD mounting system for easy on-off
  • User-serviceable for easy cleaning
  • Great sound reduction for the size

Dead Air Sandman-S Specs

  • Weight: 17.7 oz
  • Length: 6.8″
  • Finish: Cerakote
  • Materials: Stainless Steel and Stellite
  • MSRP: $1,049

Suppressor #2: Banish 30

The Banish 30 is a direct-thread suppressor that mounts on conventional 5/8×24 threads and comes out of the box as a 9″ suppressor holding eight baffles.

If, however, you’ll be shooting suppressed in tighter, more confined spaces, or you just don’t want as much can hanging off the end of your barrel, then you’ll benefit greatly from this suppressor’s modularity. It can easily break down and assemble into a 7″ configuration with six baffles. Either way, you’ll still get great sound suppression with minimal added length on your .300 WSM rifle in either configuration.

Weight is just as important as the overall length in this situation. The Banish 30 is made from a strong titanium alloy for unmatched durability at an extremely light weight. In the full configuration, it weighs 13 ounces; in the short configuration, it weighs just 10 ounces. You’ll be hard-pressed to even feel it on the average .300 Winchester Short Magnum rifle!

When it comes time for cleaning, the Banish 30 easily comes apart from both ends and is ready to be tossed in a tumbler, ultrasonic cleaner, or cleaned manually. Reassembly is a breeze due to the baffles being keyed and indexed for exact alignment.

Why We Like It:

  • Modular design to fit specific needs
  • User-serviceable for easy cleaning
  • Titanium offers great strength with minimal weight

Banish 30 Specs

  • Weight: 10 oz or 13 oz
  • Length: 7″ or 9″
  • Finish: GunKote and DLC
  • Materials: Titanium
  • MSRP: $979

Suppressor #3: SilencerCo Omega 300

SilencerCo’s Omega 300 is the lightest, shortest, quietest, full-auto rated, titanium silencer in its category. If you like to have choices and options, it even comes complete with direct thread and fast-attach mounts, as well as a removable Anchor Brake to reduce recoil, which can be replaced with a flat front cap if you don’t need the brake.

The Omega 300 is popular for all sorts of .30-caliber chamberings, including the .300 Winchester Short Magnum cartridge. That makes it one of the best multi-caliber suppressors in its class, so it will be right at home on a variety of other rifles, too. You aren’t just limited to the .300 WSM, so try it out with .308, .30-06, .300 Blackout, etc.

Why We Like It:

  • Multiple mounting options come with it
  • Comes with a brake in the box
  • Best in class specs in its category

SilencerCo Omega 300 Specs

  • Weight: 14.8 oz
  • Length: 7″
  • Finish: Black or FDE
  • Materials: Cobalt, Inconel, Stainless Steel, and Titanium
  • MSRP: $915

Suppressor #4: Banish 30 Gold

An exceptionally versatile suppressor, the Banish 30 Gold is rated for calibers from rimfire up to .300 RUM, which means it’s right at home with the .300 WSM. All Banish suppressors have been designed for unmatched sound suppression, and testing shows that the Banish 30 Gold reduces the report by 36 decibels. The average sound level heard by shooters from the Banish 30 Gold is 132.9 decibels!

Like all Banish suppressors, the Banish 30 Gold is made from a strong titanium alloy that results in unmatched durability at an extremely lightweight of just 13 ounces.

The Banish 30 Gold is an 8.2-inch quick detach suppressor holding 11 baffles, and comes with two 100% titanium muzzle brakes (1/2×28 and 5/8×24). Completely user-serviceable, you can disassemble the suppressor for cleaning in a tumbler, ultrasonic cleaner, or by hand. When you’re ready to put it back together, the baffles are keyed and indexed for a hassle-free reassembly.

Perfect for everything from a fun time at the range to big game hunting, the Banish 30 Gold will significantly reduce the report and recoil of large-caliber rifles (up to 45% in testing), while still being effective on rifles down to rimfire calibers.

Why We Like It:

  • User-serviceable for easy cleaning
  • Comes with multiple mounts, a pouch, a cover, and a baffle removal tool
  • Titanium offers great strength with minimal weight
