## What Customers Say

*AI-generated insights from customer reviews*

Owners of the HK Mark 23 in FDE often describe it as a large, serious pistol built to a high standard. The .45 ACP chambering and the 5.87-inch threaded barrel make it popular with owners who run suppressors, and the pistol is consistently described as mechanically precise.

The size is the most common point of discussion. The Mark 23 is a large-frame handgun and owners acknowledge it is not well-suited for concealed carry. For range use and suppressor host duty, owners generally regard it very positively. The accessory rail is seen as a practical feature for mounting lights.

The trigger receives mixed commentary. Some owners find it excellent with a smooth reset, while others feel it requires a period of use before it settles in. The FDE frame combined with the black slide gets aesthetic praise from most owners, though a few note the two-tone finish is not for everyone.
