Top 3 Suppressors for a Glock 23

In terms of handgun calibers, the two that tend to dominate the market are the 9mm and the .45ACP. However, there’s another one in between them that shouldn’t be overlooked, and that’s the .40S&W.

In terms of handguns themselves, Glock tends to dominate much of the market when it comes to semi-auto pistols, and so it comes as no surprise that they offer guns in 9mm, .45ACP, and .40S&W – which is the caliber we’re interested in for this piece.

Glock’s full-size .40-caliber pistol is the G22, but much like the overwhelming popularity of the full-size G17’s little brother, the G19, the G22’s little brother is the G23, and it, too, is also a very popular gun.

The Glock 23 is essentially the same gun as the Glock 19 except for the caliber and magazine capacity. Because of the similarities and because the Glock 19 pairs with a suppressor so well, it only makes sense that the Glock 23 would also make a great suppressor host.

So, what’s the best suppressor for a Glock 23? Read on and find out!

The BANISH 45 is a modular silencer specifically designed for handguns and pistol caliber carbines in calibers ranging from .45 ACP down to rimfire, which means that the .40 caliber Glock 23 is a perfect host for this suppressor.

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 Glock 23 without adding a ton of weight, which is important given the G23’s smaller size.

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.

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.

SilencerCo Omega 45K

The Omega series of suppressors from SilencerCo has a great reputation all on their own, and their K series takes all of that and shrinks it down into a smaller package. This can be a good thing since the Glock 23 isn’t a full-size .40 caliber pistol.

The Omega K suppressors are the smallest, lightest, and quietest silencers in their respective classes. With the fully welded, tubeless, minimalist Omega 45K, big sound suppression now comes in a tiny footprint.

Don’t let the size fool you. Much like the Glock 23, this suppressor packs a lot of punch in a small package.

SilencerCo Omega 45K Specs:

  • Weight: 10.3 oz
  • Length: 6.37″
  • Finish: Black or FDE
  • Materials: Stainless Steel

Coastal Gun Ultima 45

If money is a concern, Coastal Gun’s Ultima 45 is a solid option if your Glock 23 chambered in .40 caliber, but don’t mistake “less money” for “cheap.” This is a quality suppressor that won’t break the bank. They also make an Ultima 40 that would be caliber-specific for your Glock 23, but the Ultima 45 gives you some extra flexibility when it comes to host guns.

Constructed of aluminum and stainless steel, the Ultima 45 is very versatile given its size. You can use it on your .45, .40, and 9mm firearms so that you get a lot of bang for your buck and won’t be limited to just your Glock 23. In that case, then you’ll only need this one suppressor for multiple guns.
