I just bought a new Springfield XD-.45 acp service model. I like it but I can't see the sights very well. I have not so good vision and those tiny white dots just don't show up very well for me. I really like the sights that come on the Glocks. Can I get glock sights that will fit on my XD? I like night sights but I hate them in the daytime. The glock sights are alot brighter to me and also bigger and easier for me to see. I really need something like this for my XD. What and where can I get them? Thanks.
