M4 Alaskan Survival .45-70 Derringer
A 2 shot Derringer – .45-70 from the top barrel, .410 or .45 Long Colt from the bottom. As GunWebsites reports, this gun is large for a Derringer, as it would have to be to accommodate the massive .45-70 round. What do you think? Is this gun too small to be practical with a large caliber like .45-70? Some say, especially in Alaska, that a Guide Gun is a better choice. Would you purchase this gun? Perhaps has a backup gun?
