From guns you currently own, if you could take only one rifle and pistol into a SHTF/TEOTWAWKI scenario.

You can't carry multiple uppers, just one complete rifle and one complete pistol.

For me it would be my VEPR 7.62x39 and my Glock 22

AR15 and 1911.

G19 and arsenal slr.

Curious KK, why vepr over say a sam7r?  Stronger than a stamped ak but lighter than a milled one?

AR15 and 1911.

+1

I would rock the above also but maybe would substitute the AR15 for my SKS

Well I don't have a rifle yet, but I would take my Glock 17 and my Mossberg TR500.

My VEPR is scary accurate, and 100% reliable.

Daniel Defense AR-15 and Springfield XDM45.

Nemo Omen in 300winmag + HK Mark23

I'd carry my AR15 and XD45 but you probably already knew that.

I'll play, not taking ammo availability into consideration/factor-

AR15 and HK45.

My HiPoint Carbine and Pistol Less than $400

I can afford to lose them

I'd take my 10.5" AR pistol upper and put in on an AR rifle lower, Glock 22

Remington 700 270 win & Glock 23

Prolly my scoped .308 Ruger American Rifle, and Sig 220 would be most useful in a general SHTF scenario. But depending on the situation there are other considerations I might make.

My home defense go to is a cheap ass Maverick pump 12 gauge for that very reason. I can afford to have it confiscated by the cops if I ever have to use it. I'm not sure if cost is a consideration in a SHTF scenario though.

There are many highly effective combinations of firearms that would more than adequately serve the purpose.  The reality is that the more important piece of the puzzle will come down to the mindset, training, preparation and survival skill of the user as opposed to the actual tool itself.  The even more sobering truth is that there are many who think they possess the required skill sets and firepower and might also think they would do well among the masses of the herd.  The reality is that most of those "prepared" individuals are still severely lacking in ability when compared to the true meat eaters who exist out there and would not stand a chance if things got really ugly.  They would only become a prime target and a source of re-supply.   

Many will not like this answer, but it would become the truth in a true "end of days" type of scenario.     

My Tavor and Glock 17. Tavor over my AR-15 since it's shorter in case I have to clear rooms and hallways. Glock 17 cause it's more reliable than my 1911's and I can hold more ammo since it's 9mm double stacked.

My wife said her AR-15 cause it's lighter and easier to charge. Mags are interchangeable with my Tavor so that's a plus. Then she picked her 1911 cause it's the most accurate.

Pistol:  G17 >>> if lawlessness abounds, I'll be searching for some unblocked 17 rd mags, too!

Rifle:  Ruger 10/22 Takedown w/red dot scope >>> it might not bring down a big boar or antelope, but it's more concealable, more portable, and quieter than my other rifles. 

To me, this offers self defense (9mm primary, .22LR secondary) as well as a versatile rifle for hunting small game.

I'm reminded of the walking dead scene where leader of the band of men has Rick in a bear hug, and asks Rick, "what are you gonna do now sport?" Right before Rick bites his throat out.  The SCARIEST thing about that show is not the zombies, it's the people in a world without order.
