Understanding the DDM4 PDW

We could wax poetic about PDWs – and the DDM4 one in particular – but Daniel Defense did such a good job of it already, we’ll just defer to them for the short and sweet of it: “Compact and easy to transport, the DDM4 PDW is the kind of AR15 style pistol you can rely on for home and personal defense…plus it’s a ton of fun to shoot.”

The only thing we can add to the above is that putting a suppressor on it makes the DDM4 PDW even more fun to shoot!

What Are Personal Defense Weapons (PDW)?

A personal defense weapon, or PDW, is kind of a Goldilocks gun. Not quite a submachine gun and not quite a carbine either, a PDW is an in-between type of firearm when it comes to size.

PDWs are compact, magazine-fed guns that are well suited to – you guessed it – personal defense. Whether that’s in a combat situation or a home defense scenario, the PDW is at home in either. In the case of the DDM4 PDW, it’s chambered in .300 Blackout, making it a perfect gun to pair with a suppressor.

Is Suppressing the DDM4 PDW Worth It?

If you’re shooting a gun – any gun – it’s going to be worth suppressing it, and the DDM4 PDW is no different.

Using a suppressor will make the gun quieter and safer for your ears in case you have you discharge it during a home defense scenario. Shooting a gun unsuppressed in a confined space can cause permanent hearing damage. Using a suppressor can help prevent that from happening.

A suppressed PDW will also exhibit less felt recoil, making it easier for you to get back on target and administer any follow-up shots that may be needed. Whether you’re in a life-or-death situation or just having fun on the range, less recoil is always a good thing.

What to Look for in a Suppressor

Choosing the right suppressor involves a lot of different factors, but when it comes to pairing a suppressor with a PDW, two of the most important things to consider are weight and length.

Since PDWs are short and light by nature, you don’t want to add a giant suppressor to the end of the barrel. If the suppressor it too long, it defeats the purpose of having a compact gun like a PDW. If it’s too heavy, then the entire balance of the gun is thrown off.

Once you decide on an ideal weight and length, then you can start narrowing down the field of choices by things like materials, price, etc.

Top Suppressor Models for the DDM4 PDW

Without any more delay, these are our top five picks for the best suppressors to use with the DDM4 PDW.

Best Overall: BANISH 30 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 Blackout PDW.

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 your DDM4 PDW!

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.


  • Can be used with different multiple calibers, including rimfire
  • Modularity in size to fit your needs
  • Titanium construction is super strong yet still lightweight


  • Direct thread attachment only

Specs: BANISH 30

Caliber: Up to .300 WBY
Weight: 11.2 oz or 14.3 oz
Length: 7″ or 9″
Price: $999

Most Durable: Dead Air Sandman-S 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 dropping the decibels of a .300 Blackout cartridge.

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.

Dead Air designed the Sandman-S with a focus on an efficient baffle design that yields reduced recoil, blowback, and noise. With all of the elements involved in the Sandman-S’s construction, coupled with Dead Air’s lifetime warranty, this suppressor shows that good things can come in smaller packages.


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


  • Sandman-S is not as quiet as Sandman-L

Most Versatile: SilencerCo Omega 300 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 Blackout 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 Blackout, so try it out with .30-06, .308, .300 Blackout, etc.


  • Multi caliber design, so it’s not limited to .300 Blackout
  • Built with a mix of Stellite, titanium, and stainless steel for maximum reliability
  • Magnum rated for when you want to go beyond your PDW

Most Affordable: Yankee Hill Machine R9 YHM R9 suppressor product image

Don’t let the 9 in the name fool you. The YHM R9 can handle so much more than 9mm, making it incredibly versatile while still being very affordable.

If you’re the kind of shooter who likes to run high volume quantities of ammo through handguns, SBRs, and subguns, then the R9 is exactly what you need.

Shortest: TBAC ULTRA 5 TBAC - ULTRA 5 .30 QD MB

Even though it’s only 5″ in overall length, the TBAC ULTRA 5 provides top-notch .30-caliber suppression in a super compact can. Tests show that full-power hot M118LR ammo meters just 133 decibels at the shooter’s ear. That’s super impressive from a 5” suppressor! It also means that the ULTRA 5 is a great pairing with the DDM4 PDW’s compact size.

Made entirely of titanium and with the baffles joined directly to one another in a tubeless design, this material and construction combination provide a great strength to weight ratio. It’s even rated for limited full-auto fire, so go ahead and put it through the paces.

All of TBAC’s ULTRA series suppressors, including the ULTRA 5, have the flexibility to change from direct thread to CB mount and vice versa with a simple factory service operation in case your needs change.


  • Titanium is durable and lightweight
  • Available as direct thread or with a compact brake

Is It Legal to Suppress the DDM4 PDW?

Suppressors are legal to own under Federal law in 42 of the 50 states. However, state law prohibit ownership in eight states and local laws impose other restrictions in some states. There are even some situations where the DDM4 PDW itself may not be legal. As such, it’s important to consult all of your state and local laws first before suppressing your DDM4 PDW.

Can You Concealed Carry a Suppressed Firearm?

The short answer is yes, you can generally carry a concealed suppressed firearm. However, the longer answer begins with a short question: why?

Suppressors add length to their host guns, and that can hinder the ability and practicality of carrying concealed.

The biggest takeaway from this section is that if you’re going to carry a suppressed firearm, make sure you’ve got a copy of your Form 4 with you. Better safe than sorry.
