When Glock® released the new G45, we were excited, but knew it needed some improvements both functionally and aesthetically. Understanding that our MAC style cut would interfere with the factory front serrations, we set out do design a simple and clean option that would give the shooter more grip, an optic cut, and improved looks. This service is for customer supplied slides only.

**NOTE** The MAC45 slide cut can be added to any slide with or without forward serrations like G19/17/34. For 43X & 48 see the MAC43X / 48 cut. 

- Rear and top chamfers

- Extra rear serrations and added top serrations to match factory side serrations

- Includes optic cut for the Trijicon RMR.

- Available with rear iron sights forward or rearward  of optic (stock location)

- Cerakote Or Nitride refinishing
