Thanks for the input regarding ammo. I’ll offer my buddy some $$$ and see what he says.
Can’t find any shotguns anywhere right now. I was looking at the moss berg maverick 88 or the 500/590.
I can get a Ruger 10/22 or 9mm rifle right now though. Once the shotguns come back in stock I’ll pick one up.
Looking at gun safes too now. I have two small kids and don’t want them getting ahold of the gun. Found a couple at tractor supply that look nice near me. Have a spot in the closet in our master bathroom right next to our bedroom it could go.
Re the Ruger 10/22 & 9mm carbine - if you can afford to do so, get both. If not, start with the 9mm as it is a better caliber for home defense. Current events (riots, covid-19) in my mind, dictate making self defense a priority.
Note on the Ruger PC carbine - get one that has iron sights. Make sure it's in 9mm. Ruger sells one in 40 Smith & Wesson. 9mm ammo is less expensive allowing you to practice more for less $. Ruger makes a couple versions without sights included. Those require either a red dot or the addition of flip up aftermarket sights. A red dot can be added to all versions of the PC 9. Best to get one with iron sights.
You might look for a handgun that uses compatible magazines with the Ruger PC 9mm Carbine. Handguns that are compatible are the Ruger SR9, SR9 Compact / Security 9, Security 9 Compact or the Glock 26, 19, 19X, 17, 34, 45. To generalize all double stack Glock 9mm pistol mags will work the Ruger PC 9 with the Glock magazine module installed.
Either way, if you buy a Ruger 9mm carbine you will need to buy spare magazines. I would recommend at least 4 spare mags (more is always better). Glock sells magazines in the following capacities for 9mm: 10rds, 12rds, 15rds, 17rd, and 33rds. I'd recommend you get whatever is available. Stick with Glock factory mags or Magpul Glock mags.
I sent my Sister a mixture of Magpul Glock 26 - 12rd mags, Glock 19 - 15rd mags, Glock 17 - 17rd mags, and Glock 18 - 33rd mags. I also sent 600rds of ammo to include a mixture of cheap target ammo - 115gr Full Metal Jacket and "expensive" 124gr Jacket Hollow Points.
The smaller capacity mags are for 3 - Polymer 80 Glock 26 kits I sent for my 2 Nephews and Niece. All of these mags will work in the PC 9 carbine.
In regards to gun safety:
The Hunter Safety Program offered in all 50 states is a good way to learn gun safety.

I grew up in Illinois and wasn't required to take hunter safety to hunt in Illinois. A good family friend taught me gun safety and how to hunt when I was 12.
Since moving to Missouri 11 years ago, Hunter Safety isn't required to hunt on my own land. However, if I want to hunt off my land it's required. I took the online course and hands on practical class 3 years ago at age 42. I wasn't the oldest person in the hands on class. While you may never hunt, the basics of gun safety and safe gun handling are all included in the course and it's worth taking. Wisconsin uses the same Hunter Safety course that I took in Missouri.
Down the line, you really should get handgun, take a Wisconsin CCW class, and obtain a Wisconsin CCW License.
Then...
get an AR15.
