Hi all! I am going nuts trying to get proper sights for my K9. The previous owner had replaced the sights a long time ago with what I think were Trijicon night sights. I thinks that as there is some worn, barely legible white writing on the rear sight sides, which is typical of Trijicons I’ve seen. Anyway, I first ordered Williams Fire Sights off of a Fleabay vendor, as I really want fiber optic sights (gun to be a range queen, not gonna carry). When I got them, the front sight fit great, pushed on tight and is soooo bright. The rear sight though, not so much. In the first attached pic I am holding the K9 up so you can see the spaces all around it and you can see how theres no such a loctite that would take up that much slack. So...I found on Dawson Precisions website an explanation of “old” style slide cuts (wider based dovetail cut/no dimple) vs. “new”, slimmer style cuts. Looking back at where I ordered the Fire sights, sure enough they are listed for the newer style slide cut/dimpled slide. So I ordered an older style rear sight from Optics Planet. This one was by Mepro, and was a night sight (not what I want), but was the only one I could find online for the older style (pre 2004) slide cut, other than stock Kahr “i” sights. Well in the second picture attached, you’ll see me holding the K9 upside down and again, the Mepro sight is a no go as well. Does anyone have any idea what’s going on here? Apparently neither old nor new style aftermarket sights available fit my slide, but again the previous owner had aftermarket sights installed!?!? Anyone know of any fiber optic sights that might fit (or worse case some night sights), or is my slide a bastard slide?
