The LTT Red Dot Optic (RDO) Cut Solution for the PX4 Full Size
This is the same RDO solution we pioneered for the Beretta 92, available on the PX4 Full Size (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 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 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 RDO customization is for the Full Size PX4 only, for the PX4 Compact please click here.
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.
To send your slide in for the LTT RDO Cut Rebuild Package, please follow these steps:
- Add this item to your cart and check out.
- Fill out the Custom Gun Work form
- 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.
- 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.

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.

This includes but is not limited to the trigger and fire control mechanism, the barrel, firing pin, or any safety components, or slides previously cut for red dot by another vendor. If you are unsure about the status of your firearm, please call us to confirm.

Took my PX4 to the next level
This along with the LTT trigger job has made this my favorite gun. The slide cut and finish by LTT was incredible. I love this gun so much now that I was willing to sell off my Staccato P because it just sat in the safe after I started shooting this amazing PX4. Thanks LTT!!

Get the Red Dot PERIOD
I had LTT put an RMR on my Full size PX4 and wanted to let you know that the gunsmithing was excellent! My Holoson 508T fit with no issues! Zeroed it in and now the PX4 makes me look like a good shooter! If you have the opportunity to get your slide cut by LTT DO IT!

Px4 red dot
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
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?
