its good, u can apply first pressure and when the suspect see the cylinder rotate and hears a click, he know abit more pressure the rd will be discharged, like dat is better. those semi-auto pistols where got such feature....
The exact same pressure can be applied on the suspect by cocking the trigger of a Double action semi auto pistol.
Doing so switches the pistol from double to single action.
In layman term:
Got cock trigger har, i need to pull very little then got bang
I never cock, must pull hard hard.
Otherwise the same effect can be had by chambering a round.

Too much Taurus and not enough Glock?
