I was wondering if anyone on here has any experience with these. I got one a couple weeks ago and when I shot it for the first time it seems like it hits about 3-4 inches low. I have found some info online that says its common with an ultra compact and that you can get a taller rear sight to make up the difference. So I guess my actual question would be does anyone know what kind of sights I should go for or any specific company to use.
