Haven't shot it yet, waiting for the Loctite to set before I do. Just arrived today and I mounted it to my Sig P365 Legion.

Initial impressions after mounting it is that the fit is extremely tight. It took quite a bit of manipulation to get the sight to lay flat in the optic cut of the slide, once there it does not want to move. There are a couple of raised bosses around the screw holes in the slide that act as studs to help secure the optic. The fit is much tighter than the full sized Romeo X Enclosed that I have on my XTen Comp.

The optic does have a low deck height. Cowitnessing with the standard height sights is possible, barely. Only about the top 1/2 of the sights are not cut off by the base of the optic. They're usable as a backup but that's about it. A little disappointed in this as that the full sized Romeo X on my XTen Comp does allow for better cowitnessing offering a much larger portion of the iron sights to be useable.

I'm already worried that I may have made a bad choice in going with this combination as an EDC carry optic. The grip length of the Legion with the 17 round mag capacity is already long, now I've just added the height of an optic to that dimension. I have carried lightweight 1911 commander sized pistols in the past, the 365 Legion with the optic is considerably taller than that. I do have a Galco Hawkeye holster that I am going to try for carry. I like it in that it does provide some protection for the optic rather than leaving it exposed like a lot of holsters. It does have a fairly good forward can't to it and the optic portion is mostly inside the waistband so I'm hoping that minimizes the height issue. I foresee an XL grip module in my future...

Whatever finish Sig is using on their battery compartment covers sucks. Just like my full-sized unit, removing and replacing the cover with a non tapered gunsmithing screwdriver still removed a tiny bit of finish from the slot of the cover.

Overall I am impressed with it. The fit is really good and tight. Points naturally with the dot being readily visible after the draw. Yes, an old fart joining the 21st century, leaving behind 1911's and now starting to carry striker fired pistols with tv screens mounted on top.

Nice. Mine is off with my P229 slide getting milled and fitted. Very much looking forward to getting it back and trying it out.

I have an Enclosed Pro on my P226 X-Five Stainless. Co-witnesses with standard sights fine but I'll keep this in mind for the Enclosed Compact on P365's in the future.

My one issue with the Enclosed Pro is the clear sealant around the windows is a bit too visible. Sig is bad at this on most of their pistol, red dots, much worse than Holosun or Trijicon.

I open the really tight battery covers with something plastic. The cap from a disposable travel toothbrush works OK.
