Some new ammo info for Americans

Hornady Critical Duty / Critical Defense Ammo
James Tarr
It should be well-known that when looking for ammunition to be used for personal defense in a handgun, you should use some sort of expanding bullet. The most common type of these are jacketed hollow points (JHPs), and they are preferred to full metal jacket bullets (FMJs) because as a mechanism of their expansion they transfer more energy to the target. Also, because they expand, there is much less chance of them over-penetrating.

Hornady is currently offering two lines of hollowpoints with similar names—Critical Defense and Critical Duty, there’s a difference.

Hornady’s Critical Duty ammunition is high-performance full power hollowpoint ammunition not just designed for full-size duty weapons but designed to pass the famous and stringent FBI ballistic protocols.

With their Critical Defense line of ammunition, the engineers at Hornady realized that most citizens looking for ammunition for their concealed handguns aren’t likely to be shooting through sheet metal or auto glass, and will most likely be carrying smaller, lighter guns. Making ammunition for this target market didn’t require slavish devotion to the FBI protocols, because the needs of the private citizen were different. Also, most carry guns have shorter barrels, and so this ammunition is optimized for use in short-barreled pistols.

Both Critical Duty and Critical Defense rounds are tipped with what appears to be Hornady’s FTX bullet, but that’s not the case.

The Critical Defense rounds are loaded with the FTX bullet, which has a flexible polymer insert in the “Flex Tip” hollowpoint cavity which resists clogging when flying through thick clothing and/or drywall, and yet initiates expansion when it actually hits someone. The Critical Duty line is loaded with the “FlexLock” bullet. The FlexLock has the Flex Tip point, but it is paired with their InterLock band which locks the jacket and core together. This bonded core stays together better when going through intermediate barriers (i.e. the FBI protocols).

Currently Critical Duty ammunition is only available in 9mm, 9mm+P, and .40 S&W. The Critical Defense line is offered in 12 different calibers, starting at .22 WMR—any caliber you’re likely to use for self defense.
(So for personal defense the critical defense line is better for concealed carry in a smaller gun. The critical duty line is better for bigger guns that are not as easy to conceal.

If you are ambidextrous in an open carry state just put one of each type of gun in your holsters. Otherwise put the smaller gun on your person and the larger gun in your home or vehicle bubba.)
