I have been in the market for a single stack 9mm. I ended up buying the Walther PPS (pics and range report to come) but I was wondering why Glock (or Springfield XDs) do not make a single stack 9mm. Doing a search, there have been rumors of that happening for at least 3+ maybe even 5+ years, but it does not seem to be happening. I believe there is a huge market out there for a more concealable, smaller 9mm than what they make. I would have preferred to stay with the Glock platform, but I couldn't.
