That about covers it, but don't be afraid to ask more questions.
This is a topic that confuses lots of beginners.

As a note toprevious postings: Single action revolvers MUST be manually cocked for each shot. Single action semi-autos only need to be manually cocked for the first shot, which is automatically accomplished when you cycle the slide to chamber your first round.

..and just in case you weren't already confused....
There area also a few semi-auto guns that havea type of striker-fired action (Glock, Kahr, Springfield XD, etc...). This is very similar in operation to the DAO in as much as the trigger pull is the same everytime, but in the case of a misfire does not allow you to simply pull the trigger again for a second attempt at firing the same bullet. This is due to the fact that the cycling of the slide partially cocks the striker (hammer) and leaves a passive firing pin safety engaged until the trigger is pulled. The slide must be hand cycled in the event of a misfire.

Not really a big deal.Ifmy gun doesn't go bang the first time, I'd be chambering a fresh cartridge anyway.
