Some will say if it gets exposed, then it isn't really "concealed". I'll be the first to admit, I could care less whether my pistol remains unseen, or breathes fresh air. I've had people tell me "Your pistol is showing."
So? It's not like I'm parading around in my underwear. I merely wear what is comfortable. Jeans and a T-shirt. I'm not fond of IWB. The only thing that belongs inside my pants is me or possibly a pretty girl. The only way I carry my 1911 is OWB at 5:30.
I'm not going to alter the way I live. If I have to reach up to the top shelf to get that last box of Cheerios, I will. If you see my pistol while I do so, good for you. If I have to bend over to spray under my truck at the car wash, I will. If people see my pistol, good for them.
I do my best to keep from unneccessarily "outing" it. After all, it's supposed to be concealed. Under my T-shirt = concealed. However, I'm not going out of my way like some holy-rollers of CCW I've argued with seem to think is dogma. There are some who will carp and whine about "giving us CCW'ers a bad name". If you don't wrap your pistol in a blanket, shove it down your trousers in a super-tuck, wear three pairs of pants, and two sweaters and an overcoat so you can be considered to be a true CCW'er, they cry, "PARIAH!"!
Nah. For me, it's just a gun. I'll "conceal" it, but I'm not gonna hide it like it's a herpes outbreak.
