So I have a RIA A1 CS and want to change out the all black dove tailed sights. I've been in contact with Heine and they suggest sending them my slide so they can measure and see if they have anything that fits. All sounds great except the fact I'll be without my pistol for however long that takes. Not to mention all the possible things that could go wrong. My question for the community is, does anyone have any Heine sights installed on their RIA? I'm specifically asking about their straight 8 sights but not a deal breaker if I need to choose something else because of fit. Thank you in advance.
