Double Action Vs Single Action, What's the difference?
This video clearly explains the functional differences between Double Action (DA) and Single Action (SA) trigger mechanisms, using a Ruger SP101 as a practical example. It highlights that DA involves a longer, heavier pull to cock and release the hammer, while SA requires manually cocking the hammer for a lighter, shorter pull. The content emphasizes DA's suitability for concealed carry due to safety and SA's advantage for accuracy, while also issuing a crucial safety warning about decocking.
