There are 168 hours in a 7day week. Of that 168 hours, aprox 42 hours of it, I don't carry because I am asleep. But, of course, I have a firearm of some sort near me. And it isn't always a pistol. Another some 50 hours of the week, my work place requires me to be vunerable, I mean let the police protect me...
So, personally, I carry about 76 hours a week -- that is, abot 45% of the time. But I have a firearm available about 71% of the time.
During the Winter and most of the Spring and Fall, a 1911 is easy for me to conceal and I don't find it uncomfortable to carry all day (on weekends mainly for me). I'd carry my 5" XD45 tactical if I could find a good IWD holster for it.
I have warn a 1911 during the summer with a tshirt. But I am not confident of its being concealed proerply, so I mainly carry a Bera Thunder 380. However, I am considering a Glock 23 or a Sig Sauer 239-DAK for those circumstances when a 1911 is hard to conceal.
As an aside, though, remember that a gun is suppose to be comforting, not comfortable.
