Questions & Answers
The description says full size but is only listed at 3.9 inches. Can you verify this is a 4.7 inch slide and is compatible with the TXG frame?

The barrel must be 3.9 in which comes stock in m18 and p320 carry. The slide is 4.7”

So, does this include a barrel and slide components or not?

This comes with a complete slide and Romeo x pro red dot only. No barrel or recoil spring assembly.

Helpful Negative Review Improperly Advertised by Cody, Verified Owner, January 22, 2025
As advertised is a full Barrel assembly and not what I received which is just the slide. I love the slide but would’ve asked for a full description of what would be included ie, red dot and slide not a FULL Assembly

If you are looking to turn your p320 to an AXG Legion, then this is the slide to buy. Does not have the AXG engraving on it, but it will do. Romeo X red dot comes with the Pro slide, combo deal. For the price, can’t beat that deal. Took it to the ran...

Purchased the TXG grip and added this combo slide and I love it. Super easy to shoot and your groupings will be tighter. The optic is the version with the big circle around the small dot. Not sure if it says it anywhere on the description but I was u...

Product Info for SIG SAUER Pro P320 9mm Full Size XRAY3 Sights Barrel Assembly

This feature-packed slide assembly brings all the advantages of our new ROMEO-X Pro optic and the trouble-free design of our integrated expansion chamber together in one package.image

Enjoy the extremely low overall height of the fast-to-find, accurate ROMEO-X Pro reflex sight, providing co-witness with the included standard height iron sights. This no longer requires bulky, high-over-bore suppressor sights for co-witness. This slide also features our Two Port Slide Integrated Expansion Chamber for recoil mitigation, allowing for quick follow-up shots. It does all this without the need for difficult-to-maintain traditional compensated slides. This field strip disassembly on this slide is just as easy as a standard P320.
