I think it's a very worthwhile thing to note for a lot of people: having the ability to defend yourself and your family with a well-made gun actually makes sleeping at night much easier.
I know that after I bought my SR9 and S&W4040PD I slept much better at night. I bought the SR9 because of the visual/tactile loaded chamber indicator and manual safety because I knew that both of them added a level of redundancy to the safeties inherent in the DA trigger that would *allow* me to keep the gun loaded and chambered but close to my person while I was sleeping.
You touch the gun and you know whether it's chambered. No noise, no drama, no press check, in the dark, in the rain, in the middle of a hurricane. I can't imagine the stress involved in press-checking a firearm at 2 a.m. in the dark when you don't want to make noise, and I don't want to ever try it. I want to know the instant I pick it up without any noise. And with the manual safety on you can honestly say it would take an amazingly exceptional event to cause the gun to fire accidentally, probably something that would blow the house down anyway. When I looked at the alternatives I wanted a pistol I could keep under my pillow every once in a while without worrying.
I've slept better ever since I bought it.

I have friends who have asked whether I've slept with it under my pillow and I tell them: Yes. And I sleep better when I want it there.
It's a very safe gun and yet with just a bit of instruction in the manual of arms it's a very ready weapon. I don't want to be in the position of press-checking a firearm at 2:00 in the morning in the dark. I also want a pistol that I can keep literally under my head if I need to, but sleep safely in the knowledge that it's a quick series of operations away from firing, while also being almost impossible to fire otherwise. Safe *and* secure, and that's why I like it.
