What's the difference: Single action only vs Double action pistols.
This video explains the fundamental difference between Single Action Only (SAO) and Double Action (DA) pistol operating systems. It highlights that SAO pistols require the hammer to be manually cocked before each shot, while DA pistols can both cock and release the hammer with a single trigger pull, offering a second SA trigger pull after the initial DA stroke. The demonstration uses a Springfield Armory SA35 for SAO and a Sig Sauer P226 MK25 for DA.
