I absolutely agree, I believe I did ask DannyR in his blog about it ( I cannot find the post right now...) but IMHO we should look at actions in two ways: mechanical properties and user interface... By user interface Glock is SA gun, just as 1911, as much as strange this would look in initially, but if you think, in both mechanics, if you have misfire for any reason, you should operate the slide in order to chamber fresh round...
For me, in regard of the explanations in the previous two posts above, DAO is a self loading gun that will operate the striker with every pull of the trigger lever, regardless of what is the slide doing, same as P250 or for example "double strike capability" of some Taurus models...
BTW, Glock does designates his guns as "DAO" in some of their manuals, especially where they have charts with the models.
In regard of the two other pistols mentioned - the M&P and XD, I read somewhere that the trigger was designed intentionally to mimic long DA pull, even the two guns have the strikers fully cocked by the cycling of the slide...
Mr. Metkalf had a article in one of the S&W magazines, when those models came up, some 3-4 years ago if I'm not mistaking, where he was explaining the way M&P partially cocks the striker, but in the same time, there was a video by the American Gunsmith Association I believe, where you can see that the sear only releases the striker, it is not cocking it additionally... I wrote Mr. Metkalf's an e-mail, asking him to explain why the difference between his article and the video, my only intent was to learn something possibly, unfortunately I never had answer...
