Maxim Defense MD9 CPS 9mm Pistol 5.5" Barrel CQB Brace Black

The Maxim Defense MD9 CPS transforms compact firearm performance with its innovative Compact Personal Security platform. This 9mm pistol delivers rifle-like accuracy in a package sized for close-quarters applications. Built around Maxim Defense's proprietary operating system, the MD9 bridges the gap between traditional pistols and short-barreled rifles.

What Makes This Different

The MD9 CPS features Maxim Defense's patented Hate Brake muzzle device that reduces felt recoil by up to 70% compared to standard compensators. The integrated CQB stabilizing brace provides enhanced control without requiring NFA registration. Unlike blowback-operated competitors, the MD9 uses a short-stroke piston system that cycles more reliably with various ammunition weights and reduces bolt velocity for smoother operation.

Key Features

• 5.5-inch barrel with 1:10 twist rate optimized for 115-147 grain projectiles
• Maxim CQB stabilizing brace with adjustable length of pull
• Black anodized aluminum upper and lower receivers with Type III hardcoat finish
• Polymer grip module with aggressive texturing for secure handling
• Picatinny rail system compatible with standard AR-15 accessories
• Takes standard Glock magazines for ammunition compatibility
• Ambidextrous controls including bolt release and magazine release

The MD9 excels in home defense scenarios where maneuverability matters but stopping power cannot be compromised. The short-stroke piston system runs cleaner than direct impingement designs, requiring less frequent maintenance during high-round-count training sessions. Competition shooters appreciate the consistent lockup and minimal muzzle rise that enables faster follow-up shots. The platform maintains zero through temperature extremes and functions reliably in adverse conditions.
