I'll assume it happened right now and I only have what I actually own.
Rifle: AR-15 (Chambered in 5.56mm/.223)
I have the iron sights on it zeroed for 300m, picatinny rails on the front (on the back too, but I like the iron sights) for attaching all manner of accessories, saving space in my pockets for more important things. .223 and 5.56mm is readily available in almost every gun store I've ever gone too, and at 3,000 fps it has plenty of punch, but it's not as popular as some other calibers, so I wouldn't be competing as much with the guy who found the store 10 minutes before I did and raided it for ammunition. The 30-06 I have would reach out further, but the size of the ammo, the amount of kick, the 5 round capacity (not expandable), and sensitivity of a scope compared to iron sights makes it unreasonable for bug-out. I have a 12 gauge, but it's a single shot, break action, so not really reasonable if you have more than one threat you have to deal with at any given time.
Ammunition on-hand: I have a steel case that started out with 420, and still has 210 rounds of green tip, steel core, 5.56mm NATO ammunition, and more 30 round magazines than I actually have room to carry, plus a 20 rounder for shooting prone because it is shorter than the pistol grip on the lower receiver, unlike the 30 rounders.
Side-arm: Smith & Wesson Sigma - .40 Caliber - Softened Trigger
I've had this thing for a while and never ever had it offer to malfunction. After softening the trigger myself by removing two unnecessary springs I have groups an inch across at 25 yards, which if I must say so myself, isn't bad for a pistol. .40 caliber is fairly popular round, has more punch and knockdown power than a 9mm or a .22, but isn't so large that I need a hand-cannon to shoot it. The pistol has no button safeties, so if I was caught by surprise and had to quickly draw my weapon, I wouldn't have to go fumbling with buttons and switches to put it into operation.
Wife: Springfield XD Sub-Compact - .40 Caliber
Bought it, she loves it, it has tight shot groups, we can share ammunition, and it's easy for a small person to carry around without it being in the way.
Ammunition on-hand: Winchester "Ranger" law enforcement hollowpoints. I have enough for two full 14 round magazines for my S&W Sigma, and for a full 12 round and 10 round magazine for my wife's Springfield XD sub-compact.
