Turns out I'm not as smart as I'd like to pretend, and semi-automatic rifle shoots only once per trigger squeeze.
My assumption was that you can somehow get more than one shot per squeeze out of semi-automatic.
So I have some other questions:
1 - what is practical difference between semi-automatic rifle and semi-automatic pistol?
2 - I heard you can shoot about 4 rounds per second from semi-automatic rifle, is that also true for semi-automatic pistol? Does it take a true professional to shoot that fast? how fast would an average homeowner who has a semi-automatic rifle/pistol be able to shoot them?
3 - are there significant differences between different semi-automatic rifles? I'm sure caliber is a difference, but anything else? For example maybe some can shoot 2 rounds per second, and others 10?
4 - as a non-gun-owner (and never even fired one, or hold one in my hand), it would seem to make sense to use semi-automatic pistol for home protection (assuming you are going to use a gun for home protection). Would semi-automatic rifle and semi-automatic pistol be interchangeable for the purpose? When would you prefer one over the other?
Thank you
