Because Glocks literally are nothing special. Anytime a new Glock comes out you have the lovers who will jump all over it. It is THE next best thing. Even if the only change is the stippling or the color. The 19X was something anyone with a G17, G19, a hacksaw, and a can of spray paint could have done. That isn't innovation. I have shot nearly every mainline Glock there is. G43, 42, 22, 23, 21, 19, 17. And there hasn't been a single one I considered keeping for myself. The only one I ever owned was the 42 so I could sell it at a profit.
Glocks are perpetuated by internet idiots who think the Glock 19 is the most perfect firearm ever made, nope. Not even close. I love Walthers. But that doesn't mean I want to own every single model ever made. Best chances I will never own a CCP (unless the wife likes it). The PPS M2 feels way too awkward in my hand. I have no love for the Q4 or anything with a 5" barrel.
