Congrats on the shadow. I was able to snag one from Oak Hill on Monday when they came back in stock. Fired 150 rounds through it yesterday. It is definitely smoother/more refined feeling than the Sigs I am use to carrying on duty. I have the CGW ultra lite kit, reduced trigger return spring coming in to see how it improves. Also looked at the internals briefly and looks like more polishing can be done to the trigger bar. Best of luck and enjoy the new Shadow!
