[QUOTE="Glocktogo, post: 1866685, member: 1132"] A couple of points on this. A regular FMJ military 5.56 such as M-193 or M-855 round might penetrate more than say a 9mm, but there are much more effective 5.56 defense rounds for HD that penetrate less than any 9mm except frangible rounds (those frangibles are out of vogue because the frequently result in nasty, but shallow wounds that don't effectively incapacitate). Rounds such as Hornady's 5.56 & .223 TAP fit the bill perfectly. They offer very high velocity that will create a temporary wound cavity that can aid in a "one shot stop", plus they offer fragmentation that creates a very destructive permanent wound cavity. 5.56 ammo is catching up to pistol ammo in technology. Past the highly frangible rounds such as the TAP, you have rounds designed to penetrate intermediate objects such as auto glass, sheet rock, etc., yet still offer controlled expansion and deep penetration. Rounds such as the FBI's Federal M556FBIT3 62 grain Bonded Core SP's, Speer's CCI-223GDSP 64gr Gold Dot and the USMC's Mk 318 Mod 0 SOST 62gr Open Tip with a small lead core and heavy solid copper base do well in the patrol role where defeating an intermediate barrier might be critical. Handgun rounds can't so all that with good terminal effect, but they can create a sizable permanent wound cavity with effective bullet design. A round of 00 Buck contains nine .33 caliber pellets. These pellets are the least efficient design for wounding available. They can easily deflect off of or slip around bones and blood vessels and they create a very miniscule permanent wound cavity, with little to no temporary cavity. The stopping potential of 00 Buck relies on overwhelming the central nervous system with multiple pain receptors firing simultaneously, which doesn't work well if the subject is drunk, high or crazy.

Overall, an AR is more easily employed effectively by people who run the gamut from novice to expert level shooters.
