Description
You’re clearing a structure, moving with purpose. Every sound is a potential compromise. The last thing you need is a muzzle report that rings in your ears and broadcasts your position. When it comes to effective, hard-use sound suppression for your .45 caliber platform, you need a tool engineered for the task, not an afterthought. That’s the Knight’s MK23 .45 Caliber Suppressor.
The Knight’s MK23 .45 Caliber Suppressor is a dedicated, high-performance sound suppressor designed for the iconic MK23 pistol and other .45 ACP hosts. It’s built to military specifications for durability and features a user-serviceable design for long-term maintenance. Priced at $1242.48, it represents a professional-grade investment in signature reduction.
This isn’t a can meant for occasional range use. It’s built around a solid stainless steel and titanium construction that can handle sustained fire and harsh conditions. The design prioritizes full-auto rated durability, which translates to exceptional longevity for the civilian shooter. It’s a mil-spec compatible unit, meaning it meets the rigorous standards required for duty and defense use. The suppressor is user-serviceable, allowing you to disassemble it for cleaning—a critical feature for maintaining performance with heavy .45 caliber ammunition.
Mounting is straightforward and secure. The suppressor utilizes a fixed, threaded barrel attachment specific to the MK23 platform, ensuring a rock-solid lockup with no shift in point of impact. This precise fit means it’s drop-in ready for its intended host, requiring no gunsmithing for a proper installation. While engineered for the Knight’s MK23, its standard .578×28 thread pitch makes it compatible with many other .45 ACP pistols and pistol-caliber carbines from brands like Heckler & Koch and compatible aftermarket barrels.

It’s for the serious shooter who uses a .45 ACP pistol or PCC for home defense and wants to mitigate auditory trauma in a confined space.

Frequently Asked Questions
Q: Is this the actual suppressor used with the military MK23?
A: Yes, this is the production model of the suppressor developed for the U.S. Special Operations Command Offensive Handgun Weapon System (OHWS) program, which resulted in the MK23 pistol.
Q: Can I use it on my Glock 21 or other .45 pistol?
A: It can interface with other hosts, but it requires the specific fixed-mount threading and shoulder profile of the MK23 or an identical aftermarket barrel setup. It is not a universal threaded suppressor.
Q: What is the process for purchasing it?
A: As a National Firearms Act (NFA) item, purchasing this suppressor requires filing a Form 4 with the ATF, which includes a background check, fingerprinting, and payment of a $200 tax. The item ships to your chosen Federal Firearms License (FFL) holder with an SOT for NFA items after approval, which typically takes several months.
