I've been a 357 guy for a lot of years, I still think it's the best all-around, packable, shootable caliber there is, and I've taught a lot of people to shoot with it. Guns can vary from derringers to J-frames to N-frames to leverguns, I like them all. I can load them from mild to wild, mouse to moose. I even talked my chief into letting me revert from a "modern" 9mm DA auto pistol back to my revolver by shooting soda cans off the backstop at 50 yards with one. Bigger is better for some things, but unless you're shooting grizzlies, the 357 will do all that's needed most of the time.
As for "smuggling" new guns into the home past the better half, my buddy has a perfect solution. When they got married, he bought a Marlin lever-action rifle with plain wood. Over the years, he has added 12 more......she can't see any difference. As long as he only has one out at a time, she's none the wiser! :wink:
