I just stopped by to say that my favorite range gun is my CORE. I had to send it back when I got it due to a defective barrel. After a month my gun came back with a new barrel that must have been fitted properly. The trigger feels like it too was replaced. I installed Dawson fixed fiber optic...
When you shot it, was it snappy on the succeding shots? Hickok45 is a big guy, 6'8" and he thought it was snappy too. As light as the gun is I don't think too many shooters are going to follow up with the accuracy they expect. As a result, I'm sticking with my 9 Shield with Corbon ammo.
I lucked out with my M&P 9Pro. A very good trigger and a defective barrel. But one trip back to the factory changed that. They gave the gun a very good, accurate barrel. I'm happy with the gun now.
