XD-40 Sub... I went to Shiloh lastnight to test her out, but them "girls" that run the place are doing to well, it was packed... I'll try to head up there this evening and waste some paper.. I would like to get night sights installed, but was informed that I need to get a special tool to install them. Costing around $200. The sales guys warned me that if I go anywhere to have them installed, I need to becareful that they don't mess the gun up.. Is it an issue to have sights installed???
