The Grand Power .45 is an aggressively styled semi auto that is built using only high quality components and excellent ergonomics. The rotating barrel of the P45 tames the recoil of the powerful .45 ACP cartridge and makes it feel like you are shooting a 9mm! The stylish curved slide gives you fantastic handling characteristics and excellent ergonomics that makes recoil far more manageable. - CALIBER .45 ACP - MAGAZINE (1) 10rd capacity - SIGHTS Adjustable Rear
