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 the G2 Research 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 Percent of its energy to the target. The Civic Duty Round retains 99.9 Percent weight inside the intended target without concern of over penetration in CQB situations.Features :Bullet Weight: 122 GrainVelocity: 1100 FPSRounds Per Box: 20Ammunition cannot be shipped to a P.O.
