sig sauer is a great pistol. It has a 2 shot headshot and you can easily double tap it if you want those headshot kills. Its rate of fire will let you land more shots on people if you run out of ammo for your primary.
Deagle VS Colt Deagle holds 8 ammo; colt holds 7. - Deagle wins Deagle damage, 100 headshot, 37 body shot. (Can a colt user tell me the colt bodyshot?) Colt, 100 headshot. = Deagle wins so far. Deagle RoF 1 round per second. Colt RoF 1 round per 0.8 second - colt wins(I'm just guessing on this one..) Colt wins on reload speed. (We all know that) So, if you like "Light pistols"(as in fast in reload and RPM) then take a colt. If you want a "Heavy pistol"(as in good damage and more shots in the mag) then get the deagle. It's up to your play style, not the gun. Both 2 good guns. If I missed something, tell me.
You didn't take the recoil or accuracy in to play, which are both pretty big aspects of a gun. Statistics cannot tell you everything about a gun- People just have to figure out which works for them. EDIT: Also, if someone gets shot with a Deagle, you can hear it from miles away. With the Colt, as Urisk said, it's a lot quieter than the Deagle and you most likely wont even be able to tell it was a Colt that was shot.
Colt surpasses Deagle in everyway except in body shots. deagles actualy around 148 dmg to the head i think and colt does around 105 (after body armor?) but it means they both are always 1 shot head shots. The body shots on the deagle are superior in damage but colt has better fire rate, reload, and how quiet it is.
In my opinion, all guns are good, it's just the player. (And sure the huge sucks but I've seen people do good at it)
The HUGE is only good if you're going against 9 people with only 1 health each that are in VERY close area
