Maxim Defense MD9 905 CQB 9mm 5.5in | MXM-48161

The Maxim Defense MD9 905 CQB is a compact 9mm pistol built around a 5.50″ black nitride threaded barrel and an arid brown anodized aluminum receiver with a Picatinny top rail. It pairs a lightweight polymer Maxim CQB brace and M-Rax/M-Slot handguard with an ALG trigger and the RDB CQB buffer system for controlled recoil in a short package. For a robust red-dot option under $1,000 that complements the MD9’s intended role, consider the Trijicon RMR Type 2 for fast, reliable sight acquisition on a compact pistol platform.

Applications for this MD9 include range training and pistol-caliber carbine or PCC-style competition where a compact, controllable 9mm platform is preferred.
