Alright, got your attention, maybe a little misleading but something to ponder. I have long been a fan of shotguns for defense, I know they have limits for range but if you think about it there is no other gun which has the capability to deliver 2 shots faster than a double barrel, in fact most can fire both barrels at the same time and with 00 Buck there is nothing than can come close to delivering 18 chunks of 30+ caliber lead down range faster. 
I was pondering all this a few weeks ago and decided to do some tinkering. I had a double barrel coach gun with exposed hammers and decided to 'play' with it so to speak. I stripped the finish and gave it an oil rub stock to subdue it somewhat. I then installed sling swivels on the stock and barrel rib. I caution anyone about drilling and tapping the rib on a double (not a job for faint of heart) as the barrels almost touch in the center of the rib and you could easily drill into them or damage them. I finished it up by slipping a shell holder on the stock and installing a aftermarket SKS sling.I like the exposed hammers because it makes it safer to carry it loaded and is not cocked till the hammers are activated. I know it is not a gun to replace a MBR but it would make a nice supplemental piece and excellent for close range work. Even the military has had shotguns in their arsenal for over 100 years and realize their benefit and value.
Not a bad choice for a 'truck' or 'trunk' gun and if broken down it fits easily into most back packs or hand luggage.
Shotguns can be had cheap, maybe not many double barrels but certainly pumps and they to make good defense pieces (in fact the military uses pumps). I think any serious prepper should consider a shotgun in their arsenal. The shells can be reloaded by hand with no special tools and ammo may be easier to obtain one day because it is not viewed as 'dangerous' as 223 for example, even Wally Wart keeps it out on open shelves and not locked up like other ammo, I don't understand their reasoning because I can't think of ANY weapon I would dread more at close range.
