wear concealed armor, carry swift to insert Norton Earvalve plugs, know how to find/use cover, and use the right ammo in the pistol (Corbon's 100 gr PowRBall is the best commercially available, but I load my own).
90+% of the time, you won''t have to hit an attacker with a bullet, if you just get the gun out and ready in time for him to see it, and if you are smart enough to leave him an "out".
As a PFB disintegrates and the subcaliber projectiles are released to penetrate further, the multiple wound tracks produced by the penetrating fragments weaken the integrity of resilient soft tissues. In the area of maximum temporary cavity, which is usually located within the first 5-6 inches of handgun bullet penetration, these smaller wound tracks can be torn open by the subsequent stretching of soft tissues, worsening the injury. It is important to point out that there will be SOME tearing of soft tissues in the vicinity where the multiple subprojectiles begin to disperse, in the area where their separate wound paths are located close to one another. This added disruption is probably best described as a modest increase in wound trauma. But, due to the shallow location on the wound track where this increased disruption occurs (within the first 5-6 inches of penetration), a PFB is not going provide you any advantage in wounding effectiveness when compared to the wound trauma produced by a conventional JHP bullet that meets IWBA Handgun Ammunition Specifications.
