So I've come to like the looks of the X-RAY3 sights and the fact they'll fit on a 320. Looking at SIGs site, I see they offer several front/rear sight combos.
My desire would be to obtain a sight picture #2 so that my POI is at the top of the front sight. https://www.sigsauer.com/store/x-ray3.html
Which set would get me a sight picture #2 or close to that? Thank you!
