Hmm, are firearms a hobby if only 3? I got them more as a necessity than anything else. Got a CCW Ruger LC9S Pro, nice little gun that hides well, but can hit the mass above the shoulders on a snap. My other two are rifles. A Henry Evil Roy. Accurate out of the box, no tweaking of the sights needed. I use it for 75+ yard shooting and have a scope on it.
Yeah I know, You scoped a lever gun!!! I hate raccoons, and the further away I leave their bodies the better. Damned things got into my attic last year and made a mess.
My other rifle is a Ruger AR556. Man is that gun fun to shoot. Expensive though when you consider each 30 round mag cost $12 or more to shoot. I bought a CMMG .22 conversion for it with 4 mags, now I can plink away up to 100 yards with it all day for a lot less. Highly recommend the CMMG for those with AR rifles who just want to shoot paper all day. The one and only thing to be careful of is use plated ammo, not plain lead, or it will foul the barrel and gas tube.
What I do after running whatever amount of 22 through it that I want and wrapping up, I will flood some Barristol down the barrel and chamber, let it sit while I put everything away, then run a snake through a couple times, and put the 556 bolt back in and shoot a few .223 rounds through to clear the gas tube. Makes it easier to clean when I get home since the tube has been flushed.
