I own two Glocks. A model 21 and a model 19, both Gen 4's. They both have new trigger connectors and aftermarket sights, nothing more. Never had a failure with either one, and honestly it took me a long time to warm up to them. They just work, make great truck guns, not out a bunch if destroyed, etc...
In fact, the G19 is what I keep in my "Go Bag" all the time with 4 spare mags, knife, lighter, compass, flashlight and spare meds. All in a waterproof backpack of sorts...goes everywhere with me....even on the boat.
