45 suppressor guide

If there’s anything Hollywood action movies have taught us, it’s what to expect when we see a suppressor. The silencer being delicately screwed onto the tip of a firearm is the shorthand for “somebody’s about to get murdered.”

Suppressors, just to clear it up, have a better reputation than they’ve been portrayed. Their purpose is to turn ear-splitting blasts into faint, discreet thuds.

GEMTECH – Tundra &Blackside Suppressors

GEMTECH - Tundra &Blackside Suppressors

The Tundra is a dry suppressor, but it can also be used with a small amount of coolant for even greater flash and sound reduction. Its lightweight and relatively small size make for a pleasant, accurate shooting experience as compared to nose-heavy suppressors. Despite being a dry one, it outperforms most of the existing 9mm suppressors of comparable size.

It impeccably reduces sound, so if you want to be sneaky (for whatever reason), this is a smart way to avoid unwanted attention. The exciting part of this Gemtech suppressor is that it comes with a tube that can be taken apart.

You can remove the inside tube for added cleaning. This keeps residue from getting into the suppressor over time.

The center thread design offers a smooth body all the way through. This prevents you from having to shift your aim as you use the pistol. The latter is the Tundra’s bigger brother, suited for .40 S&W and 45 ACP pistols. This Blackside is available in .578-28 or Metric 16×1 LH, for fitment on a wide variety of handguns.

An aluminum and titanium alloy is used on this silencer. The design keeps the inside from wearing out due to blast corrosion.

Because being able to fire off silent shots will be the difference between being a predator and prey, the sound reduction provided here is a stunner.

PROS

  • Easy to use with many ammo types
  • Outstandingly accurate aim
  • Detachable tube makes cleaning easy
  • Corrosion-resistant materials

CONS

  • Too lengthy for smaller guns

What to Look for Before Buying?

What to Look for Before Buying 45 silencers

Believe it or not, there’s more to choosing the right suppressor than just the caliber or decibel rating. One important thing to consider is the fact that there are three types of silencers.

There are those with baffles on the inside, those with screens (or other sound-absorbing materials) around the inside, and those that are just straight-up mufflers. Here’s a list of some of the points to consider before purchasing one:

Find the Sound That Suits Your Ears

Suppressors are rated according to their decibel reduction (intensity), which isn’t quite the same as the loudness of perceived sound. Measured sound is affected by ammunition, action, barrel length, altitude, temperature, and the surrounding environment.

The numbers listed may be skewed, and what you hear is, in fact, very different from what is listed. So, the only thing you can truly trust is your ears. Practice with the suppressor you’re planning to get and test the quality of the sound.

Direct Thread vs. Quick Disconnect

The term direct thread may be a bit misleading sometimes since suppressors heat up even after moderate use. This is why it’s essential to allow it to cool before detaching it.

In this way, getting a QD won’t make that much of a difference. What it does offer, however, is freewill to use a flash hider when shooting. QD designs also perform better in maintaining tightness during full-auto fire.

On the other hand, a direct-thread suppressor mounts to the barrel without any intermediate connection. This then enhances its accuracy compared to QD suppressors.

As a result, most people would instead opt for the screw-on type. Additionally, direct-thread silencers offer a more consistent return to zero and have less POI shifts than QD designs.

Point of Impact Shift

Suppressors alter the trajectory of your shot. POI is the difference between the points where a bullet hits when shooting unsuppressed, compared to when it’s suppressed.

A high-grade suppressor will afford you a consistent impact shift, and a steady return to zero. With the suppressor on and off, your rounds should remain the same.

Size Matters

Generally speaking, longer suppressors are more silent, but they aren’t perfect. The length will affect your performance as well since it’ll be hanging at the tip of your firearm.

So, it needs to be a reasonable length. If your gun is already very long without the suppressor, then you’ll need to make your decision more delicately.

Gas Blowback

Keep in mind that the gas will need to have a place to go after firing. And with a suppressor, most people moan that the blowback is even worse. It may be chaotic and get in your eyes and disrupt functioning during rapid fire.


Different suppressors produce differing levels of blowback. So, factor this into your equation before picking an ideal suppressor for you.

Frequently Asked Questions

Can you make your own silencer?


The key to all DIY silencers is getting an adapter with the right threading to attach to the barrel and whatever you are using as a makeshift suppressor.

Another popular option is to use an oil filter or a fuel filter for a car, otherwise known as a “Tennessee silencer.”

You can find a lot of detailed video tutorials online for assembling a filter-based silencer. One word of warning: if you’re determined to make a silencer as a DIY project, be sure to stay on the right side of the law and be careful not to endanger yourself in the process physically

How long can it last for?


Review how many rounds your suppressor can work for before buying it. Some suppressors can handle thousands of rounds of ammo, but others might only work with a couple hundred.

The materials used in the construction of the suppressor may be a factor in what causes your suppressor to work for a specified period. Also, a suppressor will experience more stress if it handles a full auto shooting layout.

What are the actual benefits of using a suppressor?

After you slip on a suppressor, you can worry less about firearm-related permanent hearing loss. Though it won’t be completely silent, it’ll definitely make a notable difference with the amount of noise emitted.

Another argument is that using a suppressor can increase your accuracy. They do this is by helping to minimize flinching. Most people flinch slightly (or sometimes a lot) in anticipation of the recoil and subsequent bang.

And lastly, it’ll reduce noise complaints from your neighbors. That way, you can go around your business without bothering anyone. And maintaining peace is always a good thing.

How does a silencer work?


To understand that, you must understand what creates the noise. When you shoot a bullet, the heated gasses produced by the burning of gunpowder expand rapidly, thus propelling the ball out of the barrel.

When these gasses exit the barrel, they shift from extremely high pressure to low pressure, which creates the sound.

A barrel provides extra space to make this transition more gradual and efficient, which results in a reduction of noise.

Final Note

Think about the bigger picture. What practical application do you want your suppressor to fulfill? Do you need to be able to attach it quickly?

Can you find one that is short enough so that you don’t have to remove it? Do you value durability, lightweight, and compactness?

Whatever your priorities are, the reviews we’ve done above are some of the best .45 suppressors, guaranteed to leave you satisfied.
