I hope I can get some help identifying the rest of these guns. --redram355 (talk) 18:47, 18 March 2013 (EDT)

Hit-Girl chambering the Glock

I thought you couldn't manually chamber a round on a Double-Action-Only pistol. - User: 2wingo

You can't manually cock the hammer on a DAO pistol, chambering a round is different and is the act of pulling back the slide to pick up a round from the magazine and insert it in the chamber. This is a necessity for any automatic pistol to fire, be it a DAO, SAO or DA/SA. You can't just insert the magazine into the grip of a pistol and fire it, you need to put a round in the chamber first. --commando552 (talk) 19:32, 18 March 2013 (EDT)

Thanks. I'm still a little fuzzy on the meaning of "double" and "single" action in regards to semiautomatics. - User: 2wingo

To simplify it, in order for a gun to fire a round the gun's hammer hits the back of the firing pin, which then hits the rear of a cartridge setting it off. In a single action gun, the hammer can only be released by the trigger, so must be in the rear position to fire. Generally when you pull back the slide of a SA pistol the hammer will be cocked, but if you uncock it after this point you will have to manually pull back the hammer before you can fire again. With a double action pistol when you pull the trigger it cocks the hammer and then releases it. As a DA trigger is doing a lot more work than a SA, it is heavier requiring more force to pull. With a DA/SA pistol (what most 9mm "military" pistol are these days) they are capable of both, meaning that you can have the hammer uncocked and fire the first round with a DA trigger pull, and subsequent rounds with SA. This is putting it simply though and ignoring mechanisms like striker fired pistols and pre-set triggers, if you want to understand it I suggest you read about it. --commando552 (talk) 20:02, 18 March 2013 (EDT)
