True, and good points-but:
The odds are already in favor of the BG 9 times out of 10 -on the street anyway-I take that as a given. If anything, the occasions on which any of us will ever have to draw at all,will be in response to something.
It really depends on your method of carry, level of practice/training/experience.If one chooses to,or has to carry CC, then they'd best practice their drawing and getting off their 1st shot or double-tap-from their mode of concealment. Going to a range and picking a pistol up off the bench then popping off at stationary,paper targets at fixed distances, isnt going to cut it.
Most of the time, OC is quicker, yes-a given. But, again method of carry and training with that method can be just as quick w/ practice. I'd gotten down my draw/1-st double-tap from concealment (pocket) to very nearly the same speed as my open-draw method, so.. I feel equally confident with both. Folks going around shoving things inside their waistbands,and under shirts (and jackets/sweaters/etc in winter) are pretty much goners, on the street most of the time, I;d think.
