Easy. It's one I bought just this week.

Rossi Brawler single shot .45 Colt/.410. If there were snakes in Alaska, it would be more legit, but...nope. if I were one of the fellas that shoots halibut before bringing them onboard, but...nope. not a practice I utilize. Maybe for small game? Nope. The donut pattern from the rifling renders it useless at anything past 10 yards. It does shoot .45 Colt accurately, but...standard pressure and single shot. Anything I wanna shoot with a .45 Colt besides paper and old soda cans should probly be getting shot at with a repeater. For the person I am, and the place I live, it is the single most useless firearm I own.

I got it because it was inexpensive and novel. I like the picatinny rail on top of it, and I like the fully rifled barrel, as well as the ejector. It's fun to plink around with, but if it's to ever serve a higher purpose, I dunno what that would be.
