NEVER Mix These up! | Single Action vs Double Action #shorts
This short explains the fundamental differences between single-action and double-action trigger mechanisms. Single-action requires the hammer to be cocked before firing, resulting in a lighter 4.5 lb pull. Double-action requires the trigger to both cock and release the hammer, yielding a heavier 12-14 lb pull, as demonstrated on an Arex Rex Zero 1 Tactical.
