+P or Not +P

The good, the bad, and the ugly of +P ammo is all covered here. Its a nice read, and you owe it to yourself to go check it out.

As far as I am concerned, shootability is king. Multiple shots on target as fast as possible is the best way to make the bad guy bleed out as fast as possible. I think at a certain point you reach a point of diminishing returns and your ability to recover and put more shots on target suffers... and thats when you are doing yourself a disservice. Like with .38 vs .357 magnum, there is such thing as too much gun. Bring enough gun (caliber) to get good penetration and expansion and be sure that it is one that you can shoot quickly and accurately.

Of course, your mileage may vary.
