Product Info for G2 Research CIVIC 380 Civic Duty 380 ACP 64 Gr Copper Expansion Projectile G2 Research CIVIC 380 Civic Duty 380 ACP 64 gr Copper Expansion Projectile 20 B - Typical bonded hollow point bullets over penetrate, leading to insufficient energy transfer, damage and trauma inside the intended target. G2 Research has taken its innovative Trocar design of the solid copper R.I.P. fragmenting projectile and adapted it to Civic Duty expanding self-defense round. The Civic Duty round defeats barriers as effectively as the R.I.P. and expands 2.5 times its initial diameter after coming into contact with a fluid medium. The Civic Duty round expands to transfer 100% of its energy to the target. The Civic Duty Round retains 99.9% weight inside the intended target without concern of over penetration in CQB situations.image Specifications for G2 Research CIVIC 380 Civic Duty 380 ACP 64 Gr Copper Expansion Projectile: Manufacturer: G2 Research Ammunitions Caliber: .380 ACP Number of Rounds: 20 Bullet Type: Copper Expansion Projectile Bullet Weight: 64 grain Cartridge Case Material: Brass Muzzle Velocity: 1130 ft/s Muzzle Energy: 181 ft-lbs Application: Personal Defense Package Type: Box Included Accessories: None Primer Style: Centerfire Lead Free: Yes
