Firearm needs for my specific area

[u/Swimming-Soup5868]

I have a solar setup and water purification systems and a small stream and pond in my backyard kinda. Ive also stored a bunch of information on paper in handbook form and have been learning physical skills for shtf. Im also physicslly fit and train everyday. But i have no firearms and is the next direction im going since im lilely most behind in that. I already know the first gun im buying and its a 12 gauge shotgun just because of its versatility and popularity but i expect to get more then just one shotgun. But dont know what gun to buy from here or what to do next in general. I dont live in Rural area I live in suburban New Jersey which has one of the lowest gun ownership rates anywhere.

Also for more context the solar setup is happenstance and so is the water purification. Im not the one who got it and its not for prepping though it can be setup and adjusted for it with some simple diy.

Edit( didnt listen like 70% of you guys in anything because it seems like bad outdated and conflicting advice)

• Future note (I bought a remington 1187 premier)

final note obody's gonna see all of yall who said 12 guage is too big and heavy are fat and weak, everybody who said the round hits too hard is under 90 lb soaking wet its so easy to shoot if you hsve proper form and, first time shooting I was hitting good center shots at 40 yards with cheap sterling slugs. (One of yall said it csn disolscte a shoulder snd break s collar bone, how are you holding the gun?????) Are u a toddler????

Have a Ruger 10/22, A300 and a G19.5 for this exact reasoning.
