Firearms for SHTFI have discussed this with many of our readers, debated this with Law Enforcement and Ex-Special Forces members, and then went out into the field to try to sort out which firearms made the most sense. In a post apocalypse world I think we need to take into account 2 main items: Ammo availability and ease of finding replacement parts for the firearm in question. Taking this into account we have settle on a theme based on Common Use firearms, and their occurrence, here in the USA. Obviously we have a global base of readers, but I think you'll see the theme and be able to adapt this to your country.
Firearms recommendations:Rifle: AR-15 platform Since the AR15 platform is so widely used by sportsman, police, government agencies and our US military, ammunition and parts are widely available. This platform is highly customizable to allow it to be fit to any person and the modular architecture allows for customizations that can make it a valuable tool for any one. The recoil of the .223/5.56 ammunition is also very manageable. You can also find tons of AR-15 Accessories to customize the shooting experience to your needs or desires. If you have a hard time choosing the accessories, I'd recommend the M9 Bayonet. Personally I'd prefer an AK-47, as their durability, ease of maintenance and tolerance of horrible and extreme conditions make them a great long term use rifle, but I also must account for what parts and ammo I'll be able to scrounge in a SHTF scenario. Shotgun: Remington 870 or Mossberg 500/590/590A1 Both of these platform are widely used by sportsman, police, government agencies and our US military, ammunition and parts are widely available. This platform is highly customizable to allow it to be fit to any person and the modular architecture allows for customizations that can make it a valuable tool for any one. The recoil of the 12 gauge ammunition is fairly substantial, so the 20 gauge models might be a better fit for smaller individuals. For long term use and durability, I would think that the Remington 870, or Mossberg 500/590 would be fine, but if you want true military spec, then you'll want to up the ante to a Remington 870P or the Mossberg 590A1. I can personally tell you that the Mossberg 590A1 is a rugged, beast of a shotgun, and it can leverage the same M9 Bayonet that I'd use on my AR-15. If you need something more versatile, than a standard shotgun, you can mod your 870 with a very simple stock upgrade. This ain't your daddy's 870! There are plenty of other great shotgun accessories, regardless of your preference: Glock Accessories. It stands to reason that skirmishes and civil wars will lead to firearms and ammunition, being found at the sites of battles. These common use firearms, their parts and ammo will be found much more frequently than others, so it makes sense for preppers to have and to train with these common use firearms.
