As you can see, there are quite a number of people in our society today who harbor phobias of firearms, largely facilitated by ignorance. So when you find yourself in the company of these people, don't go showing your gun to them, unless you want to clean up urine spots on your carpet from them wee-weeing their panties. Some people are literally paralyzed or panic at the sight of a gun, like some people react to spiders or snakes, so please don't go pushing your gun onto anyone.
Conversely, there are many idiots who are fascinated by guns but know nothing about them and will, if given the opportunity, shoot themselves accidentally...or otherwise make you really regret you showed them in the first place. Plus, some people will go elsewhere and start talking about your cool guns around others, and before you know it, your place has been broken into and your gun stolen.
There is no need for any firearm to be a hazard in your home, there is nothing inherently 'dangerous' about a firearm. Guns don't shoot themselves. People are inherently dangerous, guns aren't.
The fact that you must come to forums like AT and ask shows that, although you may have been to the range a few times, you are still lacking the knowledge and skills to own a firearm safely and responsibly. Your first step should be finding qualified firearm instruction in your area and sign-up for a basic handgun safety course.
As for gun selection, since you have no desire to use the firearm for personal protection, why not get a target gun to start? Something like these will usually do the trick:
Ruger Mark II in 5 1/2"
Ruger Model Mark II in 6 7/8"
Ruger 22/45
Smith & Wesson Model 22S
Smith & Wesson Model 22A with Bull
