Build a Compact Custom EDC Pistol With Integral Red Dot Sight Mount Do you want to upgrade for your factory G43 or build a brand-new custom gun on a compatible frame from another manufacturer?

Our slide features a pre-cut slot for easy, secure, low-profile mounting of a reflex red dot sight that fits the Holosun 407K footprint (adapter plates are available separately for RMR sights).

Our G43 Slide comes with standard-height front and rear sights, which can serve as your prim Mfg: Brownells
