This can be as simple or as deep and varied as you want to make it, like fly fishing.
Town guns, backcountry guns, kit guns.. Weight, ease of carry, usage it all just depends.. Personal feel plays a lot into what works for you.
A Ruger MK (whatever) is a great first .22 to get comfortable with.
I’ve spent the last 2 years enamored with the whole “Perfect Packing Pistol” rabbit hole. They all have their time and place, from a 9mm Springfield Hellcat Pro, Ruger single-six 32 H&R mag to a Ruger 44 mag.
Whatever you get, remember it’s just a tool.
You determine its actions and its worth. Practice, practice, practice until it becomes an extension of you. Enjoy the ride.
