True, she won't see it, but just knowing I have it will annoy her.
As for counter-ambush... Isn't the possible deterrent factor of OC better than being accosted and hoping you can get your weapon unconcealed before they can harm you? And isn't it faster to draw from an exposed holster than to first have to get your clothing out of the way?
I still don't see a clear advantage... (disclaimer: I plan to CC once I get my permit, but not because it's tactically adventageous)
yeah but wouldn't the last thing you want to do is annoy your wife? i can somewhat agree it COULD be a deterrent. you could also argue cops have died from their own guns. is there eyes in the back of your head? believe me, no one here is a ninja you could get cracked in the back of the head standing in line at wal mart during rush hour.
faster to draw? nope. i can draw just as fast or faster as anyone who has a OC holster. clearing something like a t-shirt and drawing is pretty much one movement so it doesn't add time. in winter i wear a pull over and a t-shirt so nothing changes from summer to winter and its consistent. would a heavy winter coat add an obstacle? yes. you can work around it though.
no advantage? lets say I'm at a bank. its pay day and someone decides to rob it. we will say I'm OCin. robbers bust in and the first person they see is me with my OC rig. think im not going to be a target? if i were to think like a bad guy and I'm dead set on robbing the bank like the guys in the LA shoot out (back in 1993 i think) I'm probably going to get smoke checked. now lets say I'm CCing. i LOOK like a sheep like everyone else. little do they know I'm carrying a loaded gun with 30 plus rounds. i look just like everyone else. that makes me NOT be a target right away. i would have more time to think about my "counter ambush" if i choose to pull my gun. i could pull my gun when they arnt looking (they arnt ninjas either) and i COULD have my gun presented aimed in waiting in a "counter ambush" position. now they have to react. now they are caught off guard.
thats just and example. no advantage? you decide.
i forgot to add. if you are a smart OCer you have some sort of retention on your holster. depending what it is wouldn't that add time as well? would it add anymore time than clearing a t-shirt? in my own findings i see no difference.
