10mm

10mm Auto ammunition delivers magnum-level performance in a semi-automatic platform, making it the premier choice for hunting, backcountry defense, and maximum stopping power. Saint Barbs Bullets stocks full-power defensive loads including Federal HST 200gr, Hornady Critical Duty 175gr, Sig Sauer V-Crown 180gr, Speer Gold Dot 200gr, and specialty hunting ammunition from Underwood and Buffalo Bore. For training, we carry Federal American Eagle 180gr FMJ, Winchester USA 180gr FMJ, PMC Bronze 170gr FMJ, Blazer Brass 180gr FMJ, and Speer Lawman 180gr TMJ.

Developed by Jeff Cooper and introduced in 1983, the 10mm Auto was designed to deliver .41 Magnum performance in a semi-automatic pistol. It's chambered in the Glock 20/29/40, Smith & Wesson M&P 10mm, Sig Sauer P220 10mm, Springfield XD-M, and 1911 platforms. Bullet weights range from 155gr to 220gr, with full-power loads generating 1200-1300 fps and 550-750 ft-lbs of energy. Many manufacturers also produce reduced-recoil "FBI loads" (180gr at 950-1000 fps) that approximate .40 S&W performance for easier shooting.
