New P365X Slide with BUIS

Looks like Sig is starting to phase out the rear sight-plate and opting for a proper set of irons. Interesting.

Factory installed too makes for easy swapping. Not that pushing the standard height sights is overly challenging, this is still convenient.
I wish they did it this way right from the start. I purchased a Zev Z365 mostly for the better optic cut. I found a great deal on a Zev, so no regrets, but I probably would've purchased a regular Sig P365X and saved a little, if it had the new slide.

I wish they would’ve done this from the beginning. To bad they won’t let us send in our X slide for a credit towards the new X slide.

Is it me or is there a gap under the optic in the pictures?

I did the same. It cost me more money, but no regrets. One other benefit I found with the Zev slide is that the serrations are more pronounced. I get a much more positive grasp when racking with, or without gloves. If Sig would have made this option available from launch, I would have gone with it. From what I understand, Sig manufacturers these slides and barrels for Zev, so they are make money either way.

Finally they are getting it right. Looks great too. Wonder when this will hit the public sector on the actual gun that you can buy from your dealer. I have not seen this yet in my area.
Hope the XL comes out with no optic, and the options of completely stripped.

Appears to be a gap in my view as well. Sealing plates are not common from Sig. They aren’t terribly costly but the point would be for Sig to include them from the outset to maximize value for customers (haha, typing that last point felt oxymoronish).

That will be in 3 years after they release a diamond plate version, a rainbow version, and an XL slide in .380 LOL. The fact that they didn't do this from the get go makes me realize why Sig pisses me off as a company (though Iam a P365 fan)

:ROFLMAO:
That is good news. That odd rear sight plate assembly always turned me off those models.

They actually ended up making it. Kind of impressed they listened to criticisms. Took a few years, but neat. I look forward to trying one out.

Just bought a X slide last month! :(
Have these made it on the production guns you can buy at the local fun store yet? Or are they just available on the slide purchase only?

Thanks for pointing that out, and a nice option for drop-in ready, but that's not a stripped slide.

This slide looks nothing like the ROMEOZERO slide I got from Sig Sauer, the front sight is too high, and the optic is too far forward and also has the integrated rear sight, this one does not. This looks like a cheap Chinese knockoff
Looks like the P365X slide can be purchased online using MPN 8900329 and UPC798681638031. How does one know if this is the old style slide or the new one with the BUIS dovetail?
Sig answered my question. SKU: 8900983 will be the part number for the new version of the 365x slide when it becomes available.

You're an idiot. That is a factory slide from Sig. They have suppressor hight iron sights and made the rear sight/optic plate separate.
