The tubeless design ensures that vibrations will not occur within the silencer as you fire. This allows you to keep a steady shot.

A cobalt-chromium alloy is used on this silencer. The design keeps the inside from wearing out due to blast corrosion.

You can find the Omega silencer in 9K and 45K forms. The 9K model is 4.7 inches in length while the 45K unit is 6.4 inches. The 45K model fits onto not only 9mm pistols but also .45 ACP pistols and 300 BLK rifles.

9mm Suppressor Buying Guide

You need to look at how well a 9mm suppressor can be utilized when finding something appropriate for your pistol.

What Is the Suppressor Made Of?

Take a look at the materials used in the construction of your suppressor so you have something that works well for your shooting needs. A suppressor may be built with a steel body that can handle the added pressure and heat produced by the firing process.

Aluminum or some alloys may be utilized in a suppressor to reduce the weight. However, aluminum is not always good enough to handle every shot one takes, especially when an automatic gun is considered.

Titanium has become a popular material in recent years. The metal has been noteworthy for offering a dense and strong body while still being light in weight.

What Is the POI Shift?

Review the POI or Point of Impact shift on your silencer. The shift refers to how much of an adjustment you have to make when positioning your gun towards a target. The best suppressor features a minimum POI shift that should not be any larger than the size of a quarter.

Subsonic vs. Supersonic

You must review how well the suppressor will reduce the sounds produced by both kinds of ammo. Subsonic ammo is a round that will go slower than the speed of sound. This one will not produce as much noise.

Supersonic ammo produces small sonic cracks as the ammo goes faster than the sound barrier. This causes the ammo to be louder as it is fired.

How Much Does the Suppressor Weigh?

Be aware of the weight on your suppressor so you don’t have something that might be too difficult to carry around or use. A suppressor should weigh about 6 to 12 ounces on average. This may be a strong total when getting your 9mm pistol secure, so be cautious.

Check On the Cone Baffle

Look at how well the cone baffle on the suppressor is laid out. This is the tip part of the suppressor. You should have enough room around the baffle to clean it out. This allows the ammo to move out of the gun quickly and effortlessly.

The baffle may still develop a buildup of residue over time. Therefore, you must clean it out like what you would do with the regular chamber on your gun.

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 certain period. Also, a suppressor will experience more stress if it handles a full auto shooting layout.

Check the Diameter

The diameter of the suppressor should be around 1.25 inches. This is enough to fit onto an average 9mm unit.


We have determined that the best 9mm suppressor of 2021 you can use is the SilencerCo Omega. The design on this suppressor offers a simple layout. It is also easy to use with many ammo types.

Regardless of what you choose, you should see how well a 9mm suppressor can work for you. Your suppressor will not only keep the gun from being too noisy but also improve upon how you handle a gun.
