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 Civic Duty Expanding self defense round. The Civic Duty 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 Extreme Expansion of the Civic Duty leads to 100% energy transfer and total weight retention inside the intended target without concern of over penetration in CQB situations. 9-10?
