Magtech 40 S&W 180gr FMJ ammunition serves shooters who track cost-per-round as closely as they track group size. The 180-grain full metal jacket projectile — a cylinder-nose profile built for feeding reliability — leaves a 4-inch barrel at 990 feet per second, landing 392 foot-pounds of muzzle energy downrange. Brass cases and Boxer primers mean you reload the empties or hand them off to someone who does. Non-corrosive powder keeps the bore clean between detail strips. Each 50-round box ships at 1.975 pounds, classified DOT-regulated for ground transport only.
Performance at a Glance
Since 1926, Magtech has manufactured ammunition components in-house — primers, brass, bullets, and powder assembled under one roof in Brazil. The company’s vertical integration eliminates third-party variability; every lot traces back to the same raw materials and the same QC checkpoints. The 180-grain FMJ uses a lead core encased in a copper-alloy jacket, swaged to diameter tolerances that feed through Glock 22, Smith & Wesson M&P40, and SIG P229 chambers without hangups. The round-nose ogive matches SAAMI chamber specs for the 40 S&W cartridge, developed jointly by Winchester and Smith & Wesson in 1990 as a higher-pressure alternative to 10mm Auto.

The 180-grain bullet sits in the middle of the 40 S&W weight spectrum — lighter than 200-grain subsonic loads, heavier than 135-grain defense rounds. At 990 fps, recoil impulse measures softer than +P 9mm but sharper than standard-pressure 45 ACP, giving shooters a consistent platform for follow-up drills.

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.
- Treat every firearm as if it is loaded; keep your finger off the trigger until sights are on target and you have made the decision to fire; never point the muzzle at anything you are not willing to destroy; know your target, what is behind it, and what is between you and it.
- Verify that your firearm is rated for 40 S&W before chambering this ammunition. Consult your owner’s manual or contact the manufacturer if chambering markings are unclear.
- This product contains lead, a chemical known to the State of California to cause cancer and reproductive harm. Wash hands thoroughly after handling ammunition and fired cases.
