For sale is a Glock 45 that was milled (optic behind rear sight) for the RMR / Holosun footprint by jagerwerks, and will come with the pictures Holosun 507X X2 (price negotiable if you dont want the optic, but I do not have a plate for this).  The sights are blacked out / serrated Heinie suppressor height sights.  The only mods are a double undercut trigger guard, and a Wilson Combat slide lock lever. round count is roughly 4,000 and it has always been well maintained, and will include the pictured Safariland AIWB holster. $700, prefer cash, but also willing to listen to trade offers.
