WHAT RDO PLATES ARE AVAILABLE FOR THE P30 OR USP WITH LTT'S RDO SOLUTION?

We currently have options for the ACRO, RMR/SRO, the Holosun 509T, and the Holosun EPS footprint for HK P30 and USP series pistols cut for RDO by LTT.

Important Note Regarding RDO Plate Compatibility: This is not a comprehensive list of all the optics that may work with our plates. Our plates have been designed to fit tightly with the optic body of the main optic it was designed for. Other optics manufacturers may use the same footprint for mounting but have a different size optic body or may change the size of their optic body without warning. We cannot guarantee fit with all manufacturers that use these listed footprints.
