Yes, but only in two modes, and only on the Pro model. You can switch between Regular and Instant Triggers by flipping the trigger switches on the back of the controller.
The Regular Triggers are native to the Microsoft controller and have a full range of motion.
Instinct PRO will come with Instant Triggers, which act like a mouse click for faster reaction.
The Instinct PRO replaces the full-pull adaptive trigger with our dedicated Instant Triggers that provide a short mouse-click action. This hyper fast, limited motion is perfect for your favorite shooter games and getting those quick reaction shots off faster.
Please note: We recommend only using Instant Triggers in shooting games, as some games require the full trigger motion to function properly.
Attached is a video showing how to adjust the triggers.
