The LTT Red Dot Optic (RDO) Cut Solution for the PX4 Compact
This is the same RDO solution we pioneered for the Beretta 92, available on the PX4 Compact (note plates are not interchangeable between the 92, P30, or PX4)
This RDO Solution uses a very similar proprietary adaptor plate as the LTT 92 RDO system with an integrated back-up iron 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.  The screws included in the package will match your plate selection on your form. The LTT RDO Solution for the PX4 Series of pistols is currently Patent Pending. 

This Custom Gun Work package includes all of the following: 

  • A full top end rebuild to replace all of your stock components with our patented replacement components
  • Slide milling, and prep for our proprietary RDO plate as well as cerakote on the slide in Elite Black or whatever color it comes in as. IE: PX4 FDE slides, will be coated in FDE.
  • Our proprietary optic plate (See footprint options below)
  • Red dot height front sight that matches the adaptor plate built in rear sight
  • Return shipping to the same address the slide was shipped from.  
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. 

RDO Slide Instructions: 

  1. Add this item to your cart and check out. 
  2. Fill out the Custom Gun Work form
  3. Pack your slide for shipping and include the filled out CGW form. Your slide MUST BE CLEANED or you will be charged a $15 cleaning fee. 
  4. Ship the slide (signature required) & documents to the address provided on the CGW form. We do NOT need a copy of your driver's license if you are just shipping the slide.
Please allow 4-8 weeks for all work to be performed from time of receipt. Return Shipping is a fixed rate will be charged when you place your order - that includes the slide cut and cerakote.

    PX4 Storm Compact, RDO Cut

    Posted by Clay on Feb 3rd 2023

    Just received my slide back from LTT. The cut, mounting plate, and taller back up iron sights are perfect. I even got a new coating on my slide that had some holster wear. My Holosun mounted on perfectly. I highly recommend their work. No issues with function. Really good gun work.

    Out-freakin-standing! Excellent work, Holosun bolted on no problems and dialed in no problem. Turn around was well within max time stated. Bonus, sweet new cerakote finish on a worn slide. Excellent value and highly recommend.
