It is a lot smaller and lighter than my SIG 220 too, as you can see in the photo below:

The built-in LED flashlight and laser are absolutely awesome. Even in a dark room, you can easily aim this weapon and get it on target. The laser is aligned with the path of the top probe, and the lower probe will hit a couple of inches lower. Both probes must strike the criminal in order for the taser to work properly, which is something that I did not learn in researching the weapon.
The manual is quite good in going over the basics. For training for actual use, a DVD video is provided that includes a ton of instruction and tips.
The Taser C2 is a brand new second generation civilian model, that just started shipping last month. It certainly is far smaller than the first generation model, and is thus much easier to conceal. The Taser also works as a Stun gun, as a backup. The manual even outlines the best parts of the body to target, if using as a stun gun.
I was shocked to see that included among the priority targets were the testicles!!

Apparently applying 50,000 volts to that part of the male anatomy is very effective in halting an attack.
I wonder if a woman wrote this manual???
