I'm looking to replace the sights on my G23, or at least the rear sight. When I bought it, it came with green front/green rear tritiums, and I just don't prefer this combo-I find I focus on the front sight much better with at most a single rear dot. So, I have two questions: 1. I'm trying to figure out exactly what sights and sizes I currently have on my G23 so that I can figure out if I'm going to want to replace the entire set to get the POA/POI combination I want (where POI sits right on top of my front out to at least 25 yards, past that I don't really mind experimenting to figure it out, as most of my shooting doesn't reach 50 yards). They are Trijicons, marked 08 on the rear and 07 on the front. I'm not sure if the original owner of this pistol put them on as aftermarket sights or got them new with the 23. I've searched around, but I can't find a place where the Trijicon sight heights are spelled out the way some other manufacturers tell you the exact heights and notch widths. 2. For monetary reasons, I can't really use trial and error to figure out which of the sights I'm considering will work best, and since this is (sadly) my only Glock, I can't justify ordering more than one set. I have searched and found many threads related to each of these sights, but I was wondering if anyone who had any of these might be willing to post some pictures of their sight picture. I am considering the 10-8 rear (with .140 notch)/front tritium combo, Warren rear, possibly with single tritium dot (not sure if I should change out the Trij front I have now if I go that way), Sevigny carry rear (same question on front sight), and Heinie slantpro qwik, possibly with straight 8 tritium. If anybody has any of these, I would vastly appreciate a picture so I might be able to compare them, or if anybody knows the dimensions of any of these (especially notch width) I would appreciate that as well. I am definitely looking to have a little extra light on either side of the front sight-my eyes aren't bad (yet), but I prefer a good amount of air in that picture as I find I am much more accurate and precise when that exists. I know this is a little bit of a specific question on a broad range of sights, but any help is definitely appreciated!
