The modification to the SIG Sauer P365 slide, referred to as an optic cut, is a recess machined into the metal to allow for the direct mounting of a micro red dot sight. This alteration replaces the need for adaptor plates, creating a lower profile and a more secure attachment point for the optic. This enables co-witnessing with standard height iron sights, improving target acquisition speed and accuracy.
Integrating a red dot sight onto a pistol offers numerous advantages. It facilitates faster target engagement, particularly in dynamic shooting scenarios, and enhances accuracy by providing a single focal plane for the shooter. Furthermore, this enhances usability for individuals with impaired vision or those who find traditional iron sights challenging. The option didn’t exist on the original P365 release, highlighting the evolution in pistol design to accommodate miniature electronic sights.
