Maxim Defense MD9 K SCW | 9mm | 4.5″ Threaded

The Maxim Defense MD9 K SCW is a compact semi-automatic handgun configured around a short 4.5-inch threaded barrel and Maxim’s SCW pistol brace system. Its arid brown anodized aluminum receiver with an integrated Picatinny rail pairs with a black nitride threaded barrel and an arid brown polymer grip for durable, serviceable ergonomics. For an optic that complements the MD9 K SCW’s footprint and intended use, consider a Holosun 507K micro red-dot — a compact pistol optic that fits most slide-cut footprints and keeps the sight picture low and fast.

Typical applications include range training and short-range competition where maneuverability and quick sight acquisition are priorities. The MD9 K SCW is suited to shooters who want a compact, highly controllable platform for work on fundamentals and paced shooting drills.
