Freedom Arms 454 casull my fave for the past 14 years. 4 inch barrel with a bead sight. Still want to try the 500 express. 416 Rigby also one of my faves but too cumbersome for fishing. 460 weatherby cut down real short for emergencies? Winchester capsticks also fun, just be warned. Detached retinas possible when having too much fun practicing with the rifles. Guess you could carry HK 91 with 30 rounds, you might get lucky. Just saying, I think the 454 is a good small arms choice to carry. Really cool pic though.
