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 selfdefense 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.
