I didn't want to hijack Recon's "Top 4 survival guns" thread...
But lets take a look at another perspective...
1) You can only have ONE caliber
2) You're only allowed ONE rifle and ONE handgun of choice
And when I say handgun, I don't mean an AK/AR rifle and an AK/AR pistol... I mean a handgun in the purest sense.
So.. what would it be?
22 Long Rifle
-Sig Mosquito or Walther P22
-Taurus Judge (bonus being able to shoot 45 Colt)
-Glock 17/19 or Beretta 92F
-AR15 with a 9mm upper... or perhaps an Oly Arms AR15 that has a mag well dedicated for a G17/19, or maybe a Kel-Tec Sub2000 (Glock or Beretta)?
-Glock 21or 1911
-MechTech Systems .45 upper that replaces the slide on a Glock or 1911?
-Glock 33 or S&W 640
-Winchester/Marlin Lever Rifle
IF limited to one caliber... I'd have to go with the FN 5.7x28, simply because the pistol holds 20 rounds (+10 extension available) and the PS90 mags hold 50 rounds that are easily clamped two together for 100 rounds and the ammo is relatively light.
FNH 5-n-7 Pistol
FNH PS90 Rifle
The above combos are some that readily came to mind... again, the 5.7x28 being my favorite for reasons listed above. For this scenario (one caliber), yes, I realize that 5.7x28 is not readily available at most gun stores and PD's that you might "raid" in a SHTF scenario to resupply... but if you're a "prepper" like me and have a few thousand rounds stored, had to bugout and decided to bring only one caliber for two weapons.... I'm thinking the 5.7x28 and a couple thousand rounds round fit the bill... Both weapons and ammo could easily be carried in a back pack (yes the PS90 barrel would be sticking out).
I'm thinking along the lines of Shane and Otis heading into town for supplies in TWD... Look how they got stuck in the Gym...
What are your thoughts?
