Frequently Asked Questions

What makes the KAC suppressor for the HK Mk23 unique?

The Knight's Armament Company (KAC) suppressor for the Mk23 features a unique direct-thread system with an internal O-ring. This O-ring creates friction against the barrel, preventing the suppressor from backing off during firing, a common issue with other direct-thread suppressors.

How durable is the HK Mk23 Mod 0?

The HK Mk23 Mod 0 was designed for extreme endurance, successfully passing a 30,000-round military test. It is also one of the few handguns capable of safely handling high-pressure .45 Super ammunition.

What sound levels can be expected when shooting the Mk23 with its KAC suppressor?

Using a sound meter, suppressed shots with the Mk23 and KAC suppressor register around 133-135 decibels at the shooter's ear. This is significantly reduced, often making the bullet impact sound louder than the gunshot itself.

What was the purpose of the OHWS program?

The Offensive Handgun Weapon System (OHWS) program was initiated by US Special Operations Command in 1989 to standardize their diverse inventory of over 120 weapon systems, leading to the development of the Mk23.
