GRAND POWER P40 10MM Blue-GPP4010MM

The Grand Power P40 is a full-size DA/SA semi-automatic pistol chambered in 10mm Auto, built on Grand Power's Mk12-generation polymer frame with a reinforced steel dismantling catch. The P40 features Grand Power's signature rotary locking barrel system — a 4.25-inch stainless rotating barrel that distributes recoil forces more evenly than a traditional tilting-barrel design, which is especially beneficial in managing the potent 10mm Auto cartridge. The blued Tenifer QPQ slide with a rounded profile provides excellent corrosion resistance and smooth holster draw. With a 14-round magazine capacity and ambidextrous controls, the P40 delivers serious 10mm firepower in a well-balanced, ergonomic platform suited for hunting, woods defense, and range shooting.

Frequently Asked Questions

The rotary locking barrel distributes recoil forces more evenly than a traditional Browning tilting-barrel design. In a powerful cartridge like 10mm Auto, this results in noticeably reduced felt recoil, faster follow-up shots, and improved accuracy.

The P40L is the long-slide variant with an extended barrel for increased sight radius, muzzle velocity, and accuracy. Both share the same 14-round magazine and rotary locking barrel system.

Yes. Both models use the same Grand Power 14-round 10mm Auto magazine.

Yes. The 10mm Auto cartridge is well-suited for medium game hunting and woods defense. The P40's rotary barrel system helps manage recoil for more accurate shot placement in the field. For even better ballistic performance, consider the P40L with its longer barrel.
