The New PX4 Red Dot Optic Cut Solution for the 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.

Note: We will not be able to upgrade the old PX4 RDO system to the new system. If someone already has one of our old RDO cut PX4s, we cannot make this new cut into their slide. The cut is in a different location further back from the breach face of the pistol. It does not leave enough material for the front dovetail.

This RDO customization is for the Full-Size PX4 only, for the PX4 Compact please click here.

The screws included in the package are (2) Holosun to plate 4 x 40 5/16 and (2) RMR to plate 4 x 40 3/8. TORC Spec: 10 inch pounds.
