Custom Gun Work - LTT RDO Optic Cut - PX4 Full-Size

 

You asked and we listened. Langdon Tactical has developed better red dot optic cut for your PX4 slide (9mm only) using the same concept that we developed for the 92.  With this new solution, the slide is milled .140" down into the top of the slide. This system is .043" lower than the previous PX4 solution, placing the dot .915" above the centerline of the bore with a Trijicon RMR. The adapter plate will fit the Trijicon RMR footprint (see below for a list of red dot optics that fit on this plate). This RDO Solution uses a very similar proprietary adaptor plate as the LTT 92 RDO system with an integrated back-up rear sight that is matched to the height of the integrated rear sight for proper point of impact.  The adaptor is held in place with three screws and includes the front dovetail cut.
