It's unfortunate that the PPQ M2 isn't more popular. In an ideal world, we'd have the same holster selections as Glock and $20 15rd and 17rd magazines would be plentiful.
Aside from being the standard for reliability and durability, the ubiquitous nature of Glocks grants a much better selection of accessories.
Right now Im torn between glock and walther. I think the PPQ is by far the better gun, but it is lack of parts that keeps killing it for me to completly move over, and in fact, thought about selling off. If they had parts available like glock I think I would get rid of my 9mm glocks. Any other caliber, glock is hard to beat just based on barrel conversions available.
The 19 is still yet to be beat on capacity vs size that I know of? You think other manufacturers would be looking to compete with that, since it is the most quoted benefit.
