Why Glock? Why 9mm?

[Gravy Sandwich]

I've shot enough Glocks to like, appreciate and recommend them, but never owned one. For me, their grip angle makes them proprietary like Apple products. You either go all in, or none at all. My skill set is based on 15k rounds and 100k cycles of dry fire per year, and my index is not at all consistent with the Glock grip angle. In contrast, I transition almost seamlessly between STI, M&P and HK.
