Gun number one: The Ruger 10/22. .22LR is an incredibly important round to have covered; besides being the most common round in the continent (and world), it can take anything from mice to deer, if it has to, while being one of the most affordable cartridges to store and shoot (current inflated prices and availability, aside.) Additionally, if you are completely new to firearms, starting with a .22 is an absolute must. No recoil, little noise, and lightweight all make these guns easy to shoot. The polymer-stocked version of this gun is preferable for its durability and weather resistance, but not strictly necessary; threaded barrels are great to keep your options open, as well (more on muzzle accessories later).
