I've always maintained that Rodney is a good shot if he didn't panic. A genius with a degree in mechanical engineering as well as an astrophysicist, I think he can calculate the correct angle to hold his gun if he didn't freak out with impending death looming at him.

Also, I think Rodney would think he wasn't a good shot if he wasn't perfect at it. He's just that kind of person.

Killing a mouse with a P90 should be easy. Rapid, multiple bullets and all. Killing one with a sidearm would be a lot tougher.

BTW, Rodney also shot a P90 at a Wraith in "Suspicion", as well as use a taser on it.

Thanks for this interesting post.
