The Magtech 40 S&W 180 grain jacketed hollow point delivers controlled expansion and consistent terminal performance for shooters carrying mid-size or full-size 40 S&W pistols. Magtech ammunition is a defensive load built around a 180-grain jacketed hollow point projectile, launching at 990 feet per second and delivering 310 foot-pounds of energy at the muzzle. This load meets the expansion and penetration benchmarks set by modern defensive protocols, offering reliable feeding in Glock 22/23, Smith & Wesson M&P40, and SIG P229 platforms. Manufactured at Magtech‘s vertically integrated facility in Brazil, each round uses brass cases, boxer primers, and non-corrosive propellant — ensuring reloadability and clean operation across extended carry and training cycles.
Built for the Box
Magtech controls every stage of production, from case drawing to primer seating, at their São Paulo facility. The 180-grain jacketed hollow point is designed to expand predictably through four layers of denim and 12-16 inches of ballistic gelatin, matching FBI protocol standards for defensive handgun ammunition. The brass cases are drawn from new stock, boxer-primed for easy decapping, and loaded with non-corrosive powder that burns clean in short-barreled carry guns and full-size duty pistols alike. Muzzle velocity of 990 fps puts this load in the middle of the 40 S&W performance envelope — fast enough for reliable expansion, mild enough to control follow-up shot cadence in double-stack frames.

This 180-grain JHP sits in the middle of the 40 cal ammo weight spectrum, balancing penetration depth with controlled expansion. The jacketed hollow point cavity is engineered to peel back through intermediate barriers while maintaining enough mass to meet 12-inch minimum penetration in gelatin. Non-corrosive primers and powder keep chamber throats clean, and the brass cases retain enough integrity after firing to support multiple reloading cycles with standard small pistol primers and fast-burning propellants.
Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Follow the four universal rules of firearm safety: treat every gun as loaded, never point at anything you don’t intend to destroy, keep your finger off the trigger until sights are on target, and know your target and what lies beyond it. Review current laws at ATF.gov.
- Verify that your state, county, and municipality permit possession and use of defensive hollow point ammunition before ordering. Some jurisdictions restrict or prohibit expanding projectiles for civilian carry.
- Store this ammunition in a cool, dry environment away from heat sources and open flame. This product contains lead, which is known to the State of California to cause cancer and reproductive harm under Proposition 65. Wash hands thoroughly after handling ammunition and fired cases.
