I had a 1.0 9c, and didn't care for the grip size on it. It just didn't fit my hand well. Conversely, I like the smaller grip of the Shield and the bigger grip of the 2.0 9c. I guess the 1.0 9c was like the Goldilocks gun for me...too small and too big. If you can find one to try out, it may work well for you, and it should be priced really well right now. Some of the online vendors may still have some new ones.

BTW, I forgot to say in my original post in your thread, welcome to the forum!
