Well, since this is too good to pass up.
First of all, Knife:
Leatherman Multi-Tool
Emerson CQC-7 Black-T Combat folder ( an unbelievable knife ! )
Custom Made Combat Bowie overall 12."
Revolver/Pistol.
First I'd research where I was going and its history would dictate what Ammo I might find in the area, eg. Croatia I may find more 9MM than .45.
My choices:
Stainless S&W Model 686 .357
Heckler Kock USP Compact in .45 ACP +P+ or .40
Browning Hi_Power
and Ol' Reliable Colt M1911A1
With a SW Bodyguard Airweight strapped to the ankle.
Rifle, same theory applies above, but some choices:
HK93
HK MP5 (tho technically a subgun)
AK-47
Bushmaster AR15/M16 variant
Steyr Scout
Shotgun:
Mossberg 500 Defender, 9 rounds of nasty !
Whip,
JS 8 foot Whiskey
and a Lightsaber ! ! Now I'm Indiana Skywalker !
I'll think of more things too I'm sure. I'm just tired now
