It's an ok hunting rifle. I suppose it can be used as an ersatz battle rifle in a pinch. It isn't the most accurate thing by modern standards, not a military approved battle tested design. I wouldn't expect the sort of durability, reliability, ergonomics and accuracy that a Garand or something like that would have.
Also the standard magazines hold 4 shots, although I believe higher capacity aftermarket ones did exist. They are very rare, expensive and probably of questionable reliability.>>48903300
Kel Tec KSG. It's the less common version with extra long barrel and magazine tubes.>>48903404
For most problems the caliber is probably sufficient, but I would recommend a DA revolver and something with a swing out cylinder.
If you really want 45LC you can shoot it out of a 454 Casual chambered revolver.
Personally I think either 44mag/spl or 357mag/spl is more practical.>>48903607
Sniff around for a 464 Casull revolver. I think Ruger Super Redhawks and Alaskan models exist in it and aren't too expensive. That gives you a very high power option with the capability of sharing ammunition with your levergun.>>48907784
Pain in the ass but totally doable.>>48908610
Sure. You can get sub caliber inserts for 12ga flares, pistol calibers, or fire surplus flares/smoke cartridges.
How practical is that? Up to you and your imagination.>>48908844
Being alone is unwise. Extra people help watch your back. Numbers count for a lot.
Just make sure they aren't totally shitty/useless people.>>48909134
No. Even doing that with a rifle would make it an SBR rather than a pistol. The "pistol" ARs/AKs/Mares Legs you see were all built from the ground up to be pistols.
