"And the two handguns were a Glock and a SIG Sauer both 9mm, both semi-automatics that fire up to 5 bullets per second."


"Semi-automatic pistols, as opposed to fully automatic pistols, fire a single shot each time you depress the trigger until the gun's magazine is empty."


Well, even a realistic rate of one bullet every one or two seconds would do two things: empty a 9-round clip very quickly, and hit nothing (a good idea, in this case).
