"I insisted on the enlarged thirty-two-round version instead of the usual twenty-five. But still, with that little button forward on full-auto you can empty a magazine in about three seconds. It's a good way to get the attention of everybody in the room."
"Can you actually hold your aim in full-auto?"
"Well enough. The recoil's surprisingly minimal. Remember to fire in short bursts and you'll do okay." He pointed down. "Now, the cocking handle is this knurled knob here on the top. Notice it's got a slot cut in it so it doesn't block the sights. You yank it back to ready it. And don't forget, always use your left hand to cock the action and change magazines, and your right to operate the safety-selector switch."
"Got it."
"Okay, now you're ready to load." He picked one of the black rectangular metal cases out of the leather satchel on the floor. "This is a charged magazine. Always cock the action and set the thumb switch to safety before you insert one."
She pulled the knob back firmly, then pushed her thumb against the switch.
"Now feed the magazine into the bottom of the pistol grip"
She shoved it in with a click and it was secured.
"You're ready to party. Thumb off the safety and it's a go project."
"How do you take the magazine out when it's empty?" She aimed into the fireplace. For a second he thought she was going to take out a few half-burnt logs.
