Very nice
Very nice quality, fit perfectly on my P229 Legion. A little hard to get it to zero but very good overall

Pistol optic
It is a very good optic for my pistol.

EXCELLENT OPTIC!
One of the best optics I have ever purchased. Basically, Sig took their Romeo 1 Pro optic that comes with a metal shroud in some formats, and encased the metal (steel) in polymer to created a steel reinforced optic. I use mine on a competition match grade pistol. It produces excellent results. 98% lethal hit ratio! And I'm an.d guy with glasses. I ordered mine with the reticle and dot selectable choice of sight pictures. Great performance for a lower price than other higher priced optics.

Romeo RS Pro for Sig X5 Legend.
Upon opening the box, I noticed that the battery packaging was already torn apart.Looks like I received a returned product.?All the 4 screws included still has the blue loctite on them though..The red dot looks brand new without any scratches,so I decided to install it on my X5 Legend. Red dot co-witnessed with the stock front sight..It sits low on the X5.Now waiting for the loctite to set in for the next 24hrs and will go zero it at the range.Overall, I like the size of the window and it matches the full size x5 nicely.Hoping it will stay zero..I give it a 4 star because of the opened battery package.
