SS have you not shot the Mountaineer b4? I do not know why I say this but I was really impressed with mine and its ability to shoot.
I have two other Super DISC 45's and they all shoot lights out but I was really happy with the Mountaineer. After shooting it a couple of times with the factory thumbhole
But it did not take me long to drop it in a Kevlar stock. This feels much better packing around in the woods. And shoots better than I can shoot.
