I saw over at Guns Holsters and Gear that Hornady will be selling a new line of ammunition next year (2009) that is specifically designed for civilian self defense and for use in common carry handguns.
The line is called “Critical Defense” and will be available in .380 ACP, .38 Special, .38 Special + P and 9mm Parabellum.
A Critical Defense round
A common argument against hollow points is that when they are fired through heavy clothing the hollow point can clog up with fabrics and then act as a FMJ round. The Critical Defense bullets feature a hollow point with a rubber insert (same material as the Flex Tip used on the Hornady LEVERevolution ammunition) which prevents the bullet clogging up with fabric and allow controlled reliable expansion.
The idea of putting something in a hollow point to prevent it being clogged up with fabric or, in the case of hunting ammunition, fur, is not a new idea. It will be interesting to see if the Flex Tip material improves on this idea.
Another useful feature of this line is decrease muzzle flash.
For each type of cartridge and load the bullet has been individually designed for maximum performance.
