A true 1911 and 2011 style straight-pull trigger for the Ace Virtual Shooting ecosystem. The Zer0Axis Trigger System replaces the factory hinge trigger with a clean, adjustable flat face that pulls straight back on a single linear axis. No mods needed. Drop-in install with four trigger sizes. The system delivers a crisp, consistent 2011-style press with adjustable pretravel, adjustable overtravel, spring pressure tuning, and a hard stop for total control. Choose the trigger length that matches your finger reach. Design Note: Zer0Axis does not use a traditional sear mechanism. Due to the extremely short trigger travel available in the Quest FCU, a simulated sear wall does not translate consistently in VR. Instead, Zer0Axis uses an adjustable rear mechanical stop that contacts the FCU to create a clean, repeatable break. This design prioritizes consistency, reset control, and predictable press behavior rather than forcing artificial trigger staging that does not behave realistically on this platform. If you want a straighter, cleaner, more predictable Ace VR trigger pull, this is the upgrade.
