A "single action" gun needs to be first manually cocked and assuming that there is a live round in the chamber, pulling the trigger will fire the gun -- thus the gun is capable of a 'single action'.
"Double Action" implies that the gun is capable of two actions when the trigger is pulled ... (1) cocking the hammer back; and (2) dropping the hammer down.
So far, so good.
"Double Action Only" implies that the gun is capable of two actions ... that of cocking the gun and firing it but does not have the ability to be pre-cocked and left in Single-Action mode.
Some guns fit this description ... certain DAO revolvers as well as some pistols from Beretta, SIG, etc. However, there are a lot of DAO pistols out there (Glock, Kahr, S&W, Para, etc.) that are called DAO but require the striker to first be pre-cocked partially otherwise all of the pulling in the world on the trigger will not fire the gun.
To me, this is no different from the "single action" capability of a 1911 which required the hammer to be manually cocked. These DAO guns from Glock, Kahr, S&W, Para, etc.; require the internal striker to munually pre-cocked.
More accurately, shouldn't these guns be classified as 'Single Action' or maybe even 'Single Action Only'? I don't understand how they can be called "DOUBLE Action Only'.
I'm not talking about the SIGs & Beretta's which have a repeat striker capability and which truely are DAO but I'm making reference to the Glocks, the Kahrs, the Para's, and the S&W's.
