telekinetic

So, I did some testing, since I'm a HUGE dork. I'm not a big enough dork to upload the audio file anywhere, but I used garage band to time myself with the following weapons:
Sword
Knife
Shotgun
Taser
Pistol

Here's my results:

Knife, draw, close 15 feet and stab once--2 seconds
Knife, draw, close 15 feet and stab three times--3 seconds
Sword, draw and run through (or decapitate, same times)--2 seconds

So that gives us 2 seconds to work with on a melee weapon. Let's see what we can do with projectiles. I used nerf guns to ensure I had to be accurate and not just pull the trigger.

Taser, very careful aim from holster--1.5 seconds
Taser in hand, very careful aim--1 second
Pistol in a holster--1 second
Pistol in a holster, mozambique drill--2 seconds
Pump shotgun, not chambered, one shot--1 second
Pump shotgun, not chambered, 3 shots--2 seconds.

Looks like I was right with my first post--the shotgun and the taser both stand a good chance of disabling in 1 second (I wouldn't guaruntee a disabling shot with one pistol round) whereas melee weapons are taking 2. Also, times back on target may be a bit optimistic for followup shots from pistol and handgun, but the first shot times shouldn't change much.
