What is a “SA/DA” Fire Sytem?
“SA/DA” is the industry-standard abbreviation for Single-action/Double-action trigger systems.

Often viewed as one of the most reliable and safest hammer-fired pistol designs in the world, the single-action/double-action trigger system allows shooters to fire the pistol by either pulling the hammer back with their thumb or racking the slide before pulling the trigger (single-action), or by simply pulling the trigger and forcing the hammer to pull itself back prior to striking the firing pin (double-action). The single-action stage requires the hammer to be cocked (manually or mechanically) before firing, and offers a light, crisp pull, ensuring accurate shot placement and improved handling. A double-action pull, on the other hand, is much heavier and requires an intentional pull. With single-action/double-action pistols, the first trigger pull will be a double-action pull and much heavier. As the slide travels rearward, it will automatically cock the hammer, allowing you to fire with a light and crisp single-action pull with every shot thereafter.
