Please excuse the crappy cell phone picture. I got shafted on a trade, for what was suppose to be a set of night sights for my G23. Yeah, these things won't fit any glock I know of. Bummer for me. Went down to the gun store to ask the owner what the hoohaw this things fit. Apparently they're for an HK. And after poking around trijicon's site, looks like a P2000 or USP. They're dated '06. Looking for $35 shipped now. Or maybe a decent IWB holster for a G23.
