Okay, so I went though the whole thing but I (think I) only saw the front sight being replaced.......
Has anyone also done the rear sight and if so, which system did they get and installed?
I would like to also replace the rear sight if that is possible with a high visibility one. I have had Lasik surgery done to my eyes last year, and though far away (probably 3-4 feet and beyond) I feel I am at 20-20, up close (needed when focusing on the front sight on target.....) the sight is currently a blur (that is for any sight, not just the Sigma one....)! The higher visibility I think might help out with this.

Anyway, if anyone has done it or knows which would work I would love to hear about it and maybe even see some pictures. I am definitely doing at least the front sight for sure!

Thanks.
