Interesting thread, good stuff to think about. I have several so-called "assault rifles" and, like many, have thought of them as being useful tools in a home-defense context or in a SHTF situation. If the latter were to occur, a major social disruption/breakdown, I'm not likely to be as concerned with the political correctness aspects of using a black-rifle versus a lever gun. I also own a couple of the latter, a pair of Marlins, one a 45/70 Guide Gun and the other an 1894 in 357. It does strike me that the latter might make a good general HD gun for something short of a SHTF situation, might raise fewer eyebrows on the part of the police and prosecutors than would a tricked-out tacticool semi-auto. But I tend to tilt toward a handgun and shotgun combo for HD.
One thing I like about going 'old school' is that I don't like defensive weapon systems that are dependent on battery powered devices. Most red-dots, lasers, flashlights, illuminated scopes, etc., fall into that category. Not to say that I don't keep a couple of small Surefire flashlights near at hand, and also own a couple of other gizmos, but I swear that Murphy's Law seems to dictate that those gadgets all work just dandy right up until the moment that I really need them...... Go figure. I believe that reliance on battery power on a defensive gun makes the infamous internal-lock of S&W fame seem like an enhancement by comparison.
Thanks for the discussion, guys, great stuff to contemplate.
