Product Description

Maxim Defense MD:9 CQB 9mm SBR — 5.8" — 30-Round — Black

The Maxim Defense MD:9 CQB 9mm SBR is Maxim’s ultra-compact 9mm Short Barrel Rifle — bringing the same SOCOM-grade engineering philosophy of the PDX/SDX platforms to the 9mm pistol caliber carbine space. Glock-magazine compatible, the MD:9 feeds from the same standard-capacity Glock 9mm magazines you already carry. 5.8" barrel in a CQB-optimized package with Maxim’s Gen. 7 CQB stock. 9mm is inherently suppressor-friendly — subsonic 147gr loads cycle reliably and stay hearing-safe with a quality can on the MS-9 or compatible 9mm suppressor. Military-grade materials: 7075-T6 and 6061 aluminum, hardened steel components. DLC / Type III hard coat anodized black finish. Made in USA. ISO 9001:2015.

Why 9mm SBR? The MD:9 Case

The MD:9 makes the case for 9mm in a compact SBR platform. Paired with a 9mm suppressor like the Maxim MS-9, the MD:9 runs subsonic 147gr loads hearing-safe without any additional hearing protection. Glock magazine compatibility means you’re running the same mags as your sidearm. The CQB stock collapses to an extremely short overall length — making the MD:9 one of the most maneuverable 9mm SBRs available.
