Action: SA/DA – Caliber: 45 ACP – Capacity: 6 – Material: Stainless Steel Glass Beaded – Finish: Nitride – Grip: Neoprene – Barrel Length: 2.5 – Weight: 22 oz – The 9mm Rimless Revolver PITBULL uses the same unique rimless cartridge extractor assembly system as the Charter Arms .40 cal Rimless Revolver. A dual coil spring assembly located in the extractor allows insertion and retention of a 9mm cartridge in each chamber of the revolver’s cylinder. After firing the shooter can easily eject the spent cartridges for immediate reloading. Nick Ecker President of Charter Arms added Shooting enthusiasts will appreciate owning an American made revolver in 9mm and finding ammo is readily available and affordable. With its reduced recoil the PITBULL is user friendly for even the beginning shooter.
