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 G2 Research 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 Extreme Expansion of this round leads to 100 percent energy transfer and 99.9 percent weight retention inside the intended target without concern of over-penetration in CQB situations.
