Guns

[*MAD DOG*]

Ok gun nuts i have a few questions for you.

Here where i live we have a real hard time trying to qualify for a thing called a shooters license. However, in CA anyone with id can get a gun and shoot till your finger don't work no more at a shooting range.

Anyway my question is....

With a glock 9mm, when you put a new cart/mag in and take off the safety, is it true that you have to cock it before you can fire? Otherwise there would be no round in the chamber right?

Police where i live use revolvers so they can just draw and shoot if need be. With a glock you cant just draw and shoot, you need to cock it first. So if someone is pointing a revolver at a policeman and a policeman has only a glock 9mm on him, technically wouldnt the person with the revolver win because the policeman has to get his gun out of his holster, then using two hands cock the weapon before he can fire, whereas the person with the revolver just needs to point and shoot.

Am i right? If so, why the f do the police here want to "upgrade" from a revolver to a glock (apart from being able to have more ammo in the gun)?

Or do people with a glock leave it cocked in there holster with safety on?

Just wondering because i love guns, i don't own any but have always appreciated the US approach to the right to bear arms.
