Before the guntwo suggestions.
Shooting glasses. Polycarbonate lenses or anything capable of taking a hit from ricocheting rocks or lead spit out from the side of someone else's revolver. Yes, I have been hit with little pieces of stuff and it has broken skin.
Hearing protection. You don't notice that after the whistling goes away, your hearing returns, but never as sensitive as it was before. All hearing loss that stays after 24 to 48 hours stays forever. And it is cumulative.
I like revolvers because I reload. I don't like to go chasing brass all over the place. I like 22s for reasons already stated by other advisers, but I will repeat
A 22 is affordable and REALLY affordable to shoot, which is important because, to get proficient with a handgun requires A LOT of practice. 22s cost pennies a shot. the cheapest centerfire ammunition is about 8 times as expensive. You can shoot 400 rounds of 22 for the same price as one box of 38 special. Don't take my word for it. Go to a store and look at their prices.
Besides, if you want to trade in your 22 (you won't, but if you do) they hold their value well. You won't take a huge loss. A Ruger 22 Single Six is cheap and fun. A Ruger Mark II used or Mark III used or new is a great gun. Taurus has a nice 22 9-shot double action revolver as well.
Having a 22 will get you onto the gun range where you will be able to see any number of other guns (and meet their owners) and learn about them. Maybe even shoot a few.

Remember, only believe half of what you see and one quarter of what you hear. That goes double for what you get from the internet. Even this post. Maybe especially this post.
Do your own independent, confirming research when ANYONE gives you new facts on the web.
Also remember, even the idiotic stuff might have a kernel of truth buried in there somewhere.
