Idk if this is something that would be legal in every state, but most shooting ranges I’ve seen have firearm rentals. This typically helps them to sell guns because you can see how they feel, but there’s no obligation to purchase. They also might let you rent stuff that you couldn’t legally purchase without crazy licensing, like fully automatic machine guns.
I have a friend who doesn’t think it’s a good idea for himself to own a gun for similar reasons. Others here seem to be alluding to that being a huge issue, but I don’t think that’s necessarily the case. It’s weird to assume that the people who don’t want you own guns must have mental health issues. The data is clear that owning a gun makes a person significantly more likely to be harmed by a gun, whether it’s self-inflicted, an accident, a robbery gone wrong, or any number of other events. If you feel like your health and safety are at risk because of anxiety or depression or anything like that, I hope you’re able to help yourself by even just chatting with somebody who is qualified to help you, maybe getting some medication and lifestyle tips also. I found that I had a vitamin D deficiency, and just taking a standard supplement every day has had a big positive impact on my mood and attitude. Like, I still feel helpless in a shitty world that we as a species are actively making worse every single day, but now I know that that’s a problem that’s way too big for li’l ol’ me to solve. But what I can do is take a few minutes to type something to an internet stranger to tell them that they matter and that they are worth the effort of helping. You matter and you’re worth the effort of helping. Even if you don’t think it’s particularly dire, check in with yourself. Therapy is not for emergencies, so don’t wait until it’s an emergency to talk to somebody.
