My Glock is pretty old now. It's what used to be known as a 2nd Gen but is now being referred to as 1st gen. It lacks the finger grooves, "thumb rest" and accessory rail but does have the "grenat pistole" checkering on the front and back straps. In short, it isn't the old "slick side" 1st gen. But it occurred to me the other day, I haven't seen another one of similar vintage in many years. Why is this? Mine's still running fine in spite of some heavy use and pretty spectacular abuse. I used to use it as a teaching tool and would do horrible things to it that I'd never dream of doing to any other gun. Still looks fine and aside from amphib striker cups an extended slide release, and lower weight trigger bar (All Glock made) I've never replaced anything, including the recoil spring assembly. So if mine's still running, I've got to assume most of the rest of them are as well. What's the deal? Why don't they show up at the range occasionally?
