Just bought myself a 9c. Also have a single stack Walther PPS.

The 9c is actually smaller but thicker.

My fingers are too short to properly reach the trigger and trigger safety on the Glocks. The 9c is perfect for me. I will be augmenting it with a FS or maybe even a PRO for trying out some USPSA shooting, and will likely consider a Shield to replace my walther for an "identical" single stack option.

It shoots VERY nicely for me, and the aftermarket is nearly as good as the Glock if you so choose. Also quite affordable.
