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.Specifications:45 acp/168 gr/copper expansion projectile (cep)/20 per box/25 csRating: +PCaliber: 45 ACPBullet Type: Copper Expansion ProjectileBullet Weight: 168 grMuzzle Energy: 388 ft lbsMuzzle Velocity: 1020 fpsRounds Per Box: 20Boxes Per Case: 25Application: Home DefenseCasing Material: BrassHazair: Yes
