Ep.2 Singola e doppia azione. Le basi del tiro #shorts
This guide explains the fundamental differences between single-action (SA) and double-action (DA) trigger systems, using the HK USP as an example. It details how SA requires a pre-cocked hammer for a lighter pull, while DA cocks and releases the hammer with a single trigger pull, resulting in a heavier pull. The importance of the decocking lever for safely transitioning between modes and the critical safety protocols for dry fire practice are also emphasized. Instruction is provided with high authority, demonstrating expert mechanical understanding.
