These are just silly attitudes to have.
I'm not sure where this type of thinking comes from
Optimism?
Laziness?
Denial?
Well, thank you for your concise opinion of what you perceive as my attitude! I do appreciate it. After reflecting upon what is, I am certain, your deep worry and concern for my welfare and the welfare of others like me who may carry a different rig than you, I came up with some answers. Forgive me, as I did not consult other small-gun aficionados, but I do dare to speak for some of them.
I believe our thinking involves a mixture of factors, including comfort, ability to place shots correctly, personal safety, and concealability - much the same factors that influenced your own weapon choice, no doubt.
Regardless, I DO approach the day with optimism. I believe it helps. I also attempt to be lazy once a day, just as you guessed. Sometimes this, too, leads me to have a nice part to my day - after ten or twelve hours, I do enjoy relaxing, as opposed to fretting over my carry piece, locking it up, and unloading it because it's uncomfortable to have on my hip when I fall into my lazy chair. (Oops! There I go again! Special chair for it, and all!) And as far as denial - well, I don't really think I am going to get shot. Ever. I carry in case I am wrong, but statistically, I'm much more likely to die at work, in a pool, in my truck, on my motorcycle. The laws of statistics being what they are, I insure myself, but to the degree that I feel peace. That degree is typically a small .22 in a pocket, and a spare magazine next to my wallet.
I'm not really sure how a G19 is leaps and bounds beyond a .22, but if it makes you sleep easier, carry it. Some would think one reload was too few, some would think 9 is too little gun, and some would think only one gun was too few. Evidently, you do not. I'm very confident in my abilities with my pistol, and the low cost of shooting it keeps me practicing more than I ordinarily would. Its tip-up barrel means no re-chambering rounds, risking setback, which in turn reduces the amount of time I have to spend preparing and un-preparing it for carry each day. Because of that, it resides on my person, literally, constantly. And I don't even think about printing, or being made - it just never happens, something that is not so easy with my larger handguns.
I wish, sir, the same thing I wish for the rest of my carrying brethren - that your chosen sidearm keep you mentally and physically peaceful.
