Re: SHTF holster?
For SHTF, it really doesn't matter. If you feel that the holster you use to carry now is good enough, why wouldn't it be if things go south?
Of coarse, if you don't carry, I can see the point in your question. Then you need to consider, are you going to carry open or concealed? Open? Cant go wrong with a level 2 Safariland. Concealed? Any holster will work. I have a leather, open top pancake holster with straight up or canted carry position. I also have a Kydex belt slide holster, kinda presents it a good bit, but doesnt make the binding noise you get from leather. Then I have a IWB holster from Crossbreed. Its a bit different, and is a lot more location specific for comfort. You also need to upsize your pants a bit more to accomodate the additional girth. All these are used to carry either a fullsize USP40 or USP45.
