Post #7 basically says it all already.
But to answer you, I carry all the time. Anywhere and everywhere. My gun is only off of me two times in a day. When I am in the shower and when I am asleep. In those two instances it's less than an arms reach away.
So when I'm home relaxing, walking my dogs, at a family gathering, or doing outdoor activities, my gun(s) are on me.
I've been carrying my HK USP 45 for almost a month now. My secondary being a Smith and Wesson 360PD in .357. I carry two guns for a few reasons.
The HK USP 45 is on my strong-side and my spare mag is in my front left pocket. Multiple threats, missed shots, barriers, and for the unknown. More ammo is always better than less ammo. If you don't need them all, even better. If you do need them all but don't have them, the day gets worse.
My Glock 19 is getting some custom work done, so it's been at my friend's and he got into an accident, so it'll be a while. I picked up an HK USP 9 Compact from another friend locally, I won't be carrying it until I get 2-3 more spare magazines that are from HK directly. I don't trust anything else for this gun.
So, USP 45 and now the Smith and Wesson 360PD. Why a second gun? I'm with my fiance, a family member, or a friend more often than not when I'm out and about. If I decide to stop for a snack while they wait in the car, or pump gas, or separate at any moment, I can hand my pistol to my loved one or leave it in the car. Especially if something goes really bad or I have the luxury of realizing it's about to go bad.
Second reason for the J-Frame revolver. If I am in a very tight scuffle where I cannot get to my HK and I guarding it I can usually always get to my KaBar TDI knife or....My J-Frame. The reason for the J-Frame is that it does not go out of battery if I was to jam it into an attacker. I could fire off all the rounds necessary to stop the threat without having a malfunction occur.
So it all depends. On you, on what you want training in, on what makes sense to you, etc.
People are constantly and I mean constantly attempting to discredit someone else's thought process for why they do what they do but trying to hack it down and poke holes in their logic. Fact of the matter is, different experiences lead to different preferences. DA / SA vs Striker. This bullet vs that bullet. This knife in this position vs that knife in that position. So on and so forth.
If it's dangerous it should be pointed out, if it's different than yours, simply move on.
Attempt to draw your own conclusions. I've taken classes with different people, they all do things differently and I disagree with some things, but I respect them enough to give them money, so I do it. Then I incorporate my own logic into what they're taught me.
