Ok first you are going to need a few things.
You will need the takedown tool. Some kind of punch, I'm using a Dubro ball head hex driver for my R/C race truck. And some sort of small lightweight device to tap with, I'm using a screwdriver.
Figure 1.1
You will also need something to grip with, I'm using self locking tweezers, but you could use hemostats, or if you are really adept with strong fingers, you can use regular tweezers.
Figure 1.2
Of course you will also need, THE GUN!
Figure 1.3
Now first thing is first, don't be a douchebag, CLEAR THE GUN!!!!!
Check the chamber, then check the mag well. Then feel the chamber, then feel the mag well. Now go and visually check the chamber and the mag well again.

Ok done? Well guess what? I DON'T BELIEVE YOU, GO DO ALL THAT AGAIN TO MAKE SURE! You want no risk of putting a round through the wall and into someone's head. Remember if you follow the rules of firearm safety then it is IMPOSSIBLE for anyone to be hurt, so please just do it again. I take no responsibility for yourstupidity, ignorance, OR ARROGANCE!
Ok done? Great, lets move on.
