I don't know if I'm in the minority here, but I like my glocks to look...well glocky. Blocky, matte carbon/black. Something utilitarian and sexy about it. Maybe with some functional changes like tapering the front of the slide, or a RDS cut. Biggest change, if you need it, is probably a trigger upgrade. I personally don't like front cocking serrations, press check or not, as its too close to the business end for my comfort IMO
