Smith & Wesson M&P 9: Precision Semi-Auto with Custom Costa Mods

For operators and enthusiasts who want a balance of stock reliability and race-ready ergonomics, this review dives into a highly modified striker-fired 9mm platform optimized for fast, accurate follow-up shots and controllable recoil. Below I break down the specific Costa package upgrades, handling characteristics, and what to expect on the range and in the holster.

SMITH & WESSON M&P 9 is equipped with the M&P Costa modification package that converts a standard M&P into a competition-minded semi-auto ready for defensive and performance use. The Costa package includes Half Top Serrations, Front Side Serrations, Top Porting and Side Porting with Slabbed Sides, an ISMI 20lbs recoil spring installed (22lbs recommended for +P+ ammunition), and exclusive Custom Laser Engraved Costa and ATEi logos.

Key Features and Upgrades

The slide is refinished in Hard Nitride Black for enhanced wear resistance and low-friction cycling. Sight package is a 10-8 Performance Red Fiber Optic front paired with a U-notch rear for quick sight acquisition. Trigger work reduces pull to approximately 4.5lbs with minimal over-travel for a crisp, predictable break. Stippling follows a traditional 360-degree pattern in medium texture and includes one backstrap; ergonomics are further refined with a trigger guard undercut, mag-well bevel, and front index points for faster reloads. The pistol ships with one 17-round magazine and does not include a case. View product details and pricing here: View product details

Performance & Handling

Top and side porting paired with a lighter recoil spring (20lbs) tames muzzle flip and speeds follow-up shots. For users who plan to shoot higher-pressure loads, the 22lbs recommendation for +P+ helps preserve reliability while controlling slide velocity. The combination of fiber optic front sight and reduced trigger pull makes this platform ideal for competitive carry-style divisions, practical courses, and defensive drills where rapid, precise hits matter.
