Window Cut Design The slide features multiple window cuts that reduce overall weight while maintaining structural integrity. These cuts lower the reciprocating mass of the slide, which can contribute to faster cycling and reduced felt recoil. The windowed design also gives the Glock 43 a modern, aggressive appearance that sets it apart from standard factory slides. Holosun 407K Optic Cut The slide is machined with a dedicated Holosun 407K/507K footprint, allowing for direct mounting of popular micro red dot sights such as the Holosun 407K and 507K. This low-profile optic cut enables a lower mounting height and better co-witnessing with iron sights, improving speed and accuracy for shooters who prefer red dot optics.

The complete, drop-in design allows for quick installation on standard Glock 43 frames without the need for gunsmithing.
