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.

Best Buy for the money!! Installs easily and is simple to sight in and doesn’t lose its zero!!! Sig has done it once again!! Defiantly a home run with the steel housing under the polymer , so it’s able to handle racking! Perfect fit for my M18 !!!
