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. The LTT RDO Solution for the PX4 Series of pistols is currently Patent Pending. 
 
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.

To send your slide in for the LTT RDO Cut Rebuild Package, please follow these steps: 

  1. Add this item to your cart and check out like any other product. 
  2. Fill out the Custom Gun Work form and include your order number (five digit number you receive at checkout). If you want to add any other work to your slide such as different levers or a top end rebuild, please note that on this 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. 
  5. LTT will notify you when we are returning the slide
Please allow 4-10 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. You are responsible for inbound shipping and following all processes listed on this form.

    Px4 red dot

    Posted by Alex law on May 29th 2022

    This is the best quality red dot cut and customer service hands down ! I asked a million questions and alswaya got a great reply . The team at langdon tactical is top notch the rmr cut took 8 weeks on the nose so. Not too bad turn around time the back up irons are sweet and the dot stays zeroed . Will be sending more guns to langdon in the future . My only hope is that they release a backup parts kit because when you get a slide milled they change some internal parts .

    Excellent

    Posted by Chris Stump on Jan 1st 2022

    So glad LTT took the time to perfect this RDO cut. The workmanship is excellent. The incorporated backup iron sights are perfect. The cerakote is blemish free. I'm very happy with this purchase, and look forward to competition with this superb firearm next year. Only question is where to find a holster...I prefer a Fobus paddle, but they say there are no plans to make one. Ideas?
