Yup, they sure do in big dots and standard dots -I have some two dot sights on Sig Pistol, they are good but not better than 3 dot. I wonder if XS makes a big dot front sight for this rascal?
Best to have a dot set up your glass's with a section designed for a distance of your front sight. More4 commonly known as computer lens. Also a fiber optic front sight or both sights go a along way in helping to "see" your sights . There are night sites that also have a fiberoptic ring in them. Just need to deside what color is best for you. Green ,red yellow ang orange. I prefer green front. I also tend to be good with a all black rear sight. Places all my focus on the front.
Theres some on this page to give you a basics.

Are the big dots an issue with holsters?
I always seem to gravitate back to Heinies, currently the Ledge design. J have one pistol with 10-8 FO front and standard U-notch rear which is similar. I also have a set of Trijicon Orange HDs on a pistol. The result is a big Orange blurr. Have tried XS Big Dot but found that arrangement didn't work well for me. Best thing I can suggest is to shop the options and work with your eye doc.
