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 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, including new decock levers.
All PX4 RDO slides are G-model decocker only; if you send in an F-model (safety) slide, it will be converted to G-model decocker as part of this package.
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.

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.

High Quality, well done RDO cut

Posted by Seth on Jun 16th 2023

I just received my slide after having the work done, and I must say I am very impressed! It came with everything needed to attach the dot to the slide, including screws, bits and thread locker. The plate came with witness marks, so you can check if they came loose during shipping. The fit and finish is remarkable, and the base of my red dot sits below the top of the slide. The only real negative to this process is the long lead times due to how popular this service is. The product is a 10/10 and I WILL be recommending this to anyone looking for an RDO cut on any Beretta.

Took my PX4 to the next level

Posted by Patrick on Jul 22nd 2022

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

Posted by CJ Moore on Jul 6th 2022

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

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?
