Looks like a nice gun. Personally, I prefer shotguns and rifles, both for home defense and sport.
For home defense, I just feel like nothing intimidates like a 12 gauge, it's got a pretty damned low likelihood of missing, and it's much, much less likely to penetrate through walls and go on to injure innocent people. It's also, much, much more difficult to waive a shotgun or rifle in a way that accidentally points it at somebody unintentionally (try pointing a broom at the floor, the ceiling and behind you, vs pointing a carrot in the same directions, for example.)
For sport, eventually I get pretty damned bored shooting at small stationary targets. When you can go out with a couple friends though and blast at 50 or 100 clay pigeons, it's a hell of a lot more fun. Maybe it's especially nice for me because I typically tend to be the best or second best shot in the group, which is a skill that literally took me 20 years to develop. When I'm clowning around with friends a little it's fun to show off by throwing 2 pigeons (one hand thrower in each hand) and seeing if I can pick up my gun and hit 'em both. It's pretty much the only outdoors activity I can do where I feel like I can be at near elite-level on a given day.
Then you add in the potential to go out and hunt, and the big guns can't be beat. So many great memories crawling the mountains of Idaho looking for grouse, chukar, partridge, deer, turkey, moose....now that I'm moving to England I plan on going after wood pigeon and goose more.
If I were you, though, OP, I'd have a hair trigger about giving up my guns at the very first sign of depression. I love what my guns allow me to do, but I've been around a lot of mental illness in my life, and I don't know anybody who really gets "cured." You have good times and bad times, and when things get good it's maybe easy to hope that it never goes bad again. But it probably will.
The suicide rate among states with high gun ownership are astronomically higher than those with low gun ownership. It's not that gun owners are more suicidal, it's just that guns are so much more effective than any other means. If you feel things start taking a dark turn, just get rid of the guns. It's just an object like any other--you can buy a replacement for about the same price you sell it, so it's no problem in the big picture to take some time off while you sort things out. You've probably already thought this through, so sorry if I sound patronizing.
TL/DR: Fuck the pea shooters, get yerself a scattergun. It's safer, more fun, better home defense and you can kill critters! Also, don't shoot your eye out.
