I would run away...b/c one bad guy is like eleventeen sight pictures, where two or three bad guys is like 1, 2, ahhhh 3, plus ahhhh whatever, I'm just going to run away because of the math alone.
Is it more "tactical" to put 1 bullet in each bad guy first and than follow up on who ever is still looking scary. Or should you shoot each with two bullets and follow up with Mr Scary? Wait how many sight pictures is that? Ehhhh?
I give up.
