Largest TV page
 

I did a count. On pages that are split once a particular gun shows up in a season they aren't counted again in later ones. They might be 1 or 2 off but fairly close.

The Unit = 124

24 = 119 (some pages are incomplete, not sure about the weapons list)

Miami Vice = 114 (Season 5 still needs to capped)

NCIS = 103

Burn Notice = 102

Stargate SG-1= 80

The A-Team = 78

Mail Call = 77

One page that still needs to be counted is Hunter.

SG-1 used to be before it was broken up like 24

It's in the list at 80, whether it's broken up or not it doesn't matter when counting the total number of "different" weapons used throughout the series.
