Product Description
Install a compact red dot on your Glock 43 without milling the slide. This Shield Sights low-profile slide mount replaces the factory rear sight with a slide-in rear sight and mounting plate, providing a clean, flush fit for RMSc and SMSc optics. It also accommodates the standard RMS, SMS, SMS2, and JPoint optics with slight width overhang. The RMSw can fit but may not fully seal because the plate is narrower than the RMSw and its gasket. Designed specifically for the Glock 43, this mount offers a straightforward upgrade path for modern optics.
