Maxim Defense SDX Pistol – 300 Blackout | Arid Finish (MXM-49215)

The Maxim Defense SDX Pistol in 300 Blackout (MXM-49215) delivers elite-level performance in one of the most compact AR-platform pistol configurations available today. Built on Maxim Defense’s proven SCW (Super Compact Weapon) architecture, the SDX combines an ultra-short profile with serious ballistic capability — making it an ideal choice for home defense, tactical applications, and discerning collectors who refuse to compromise.

Chambered in 300 Blackout, the SDX is engineered for maximum versatility, cycling reliably with both supersonic and subsonic ammunition. This makes it an exceptional suppressor host, allowing users to optimize the platform for hearing-safe, reduced-signature performance. The Arid finish gives the firearm a rugged, field-ready aesthetic while providing durable protection against the elements.

Maxim Defense is known for uncompromising mil-spec construction, and the SDX is no exception. Every component reflects the brand’s dedication to precision engineering, tight tolerances, and long-term reliability under demanding conditions.
