I have a Thompson Contender with a 10"
.357 Maximum barrel and a 14" .222 barrel. Both are fun to shoot, but the .222 is VERY LOUD and has a ton of concussion with that short of a barrel. My favorite pistol is my Browning Buckmark Plus .22LR
Its very accurate and looks great - stainless barrel and slide with a black frame and grey and black composite grips.
I like shooting all kinds of guns at all kinds of targets, but I don't think there's anything more enjoyable than plinking cans with .22! You can do a lot of shooting without breaking the bank and don't need a long distance like you do with big bore rifles. And you only need to be accurate enough to kick the can around. Some of my fondest memories growing up were Sundays spent at my grandparents with all my uncles and cousins, spending the afternoon going through 1000's of rounds of .22's....back when they came in "bricks", not bulk.
It's not about how many guns you have (o.k., maybe a little!) but rather using and enjoying the ones you have.
