Last Man Standing (1996)
Crew or equipment visible
The grips and mainspring housing (MSH) are interchangeable parts between 1911 and 1911A1, so an original 1911 can look like a 1911A1 by swapping these parts. Modern 1911 pistols makers don't even distinguish between 1911 and 1911A1 anymore (because they all have the crescent cutout). The only thing the A1 model has that cannot be had on the original 1911, is the half-moon/crescent cutout behind the trigger guard.
Incorrectly regarded as goofs
The power for Jericho comes from gas generators (Smith's conversation with the bartender); Jericho is in the middle of nowhere. The poles shown only extend so far and their sole purpose is to provide light just so far out-of-town because the town has few resources.
