I also got a new Shadow 2 this week.
There are/were two issues with it.
1. The checkering on the grips and backstraps felt aggressive and harsh while handling it.
This harshness didn't bother me while shooting it yesterday. I didn't even notice it.
The gun did; however, really make me look good when I shot it.
After shooting the gun, I no longer see the harshness of the grips as a problem.
2. Like cattivo, The angle of the slide, and the low contour, make it difficult to rack it.
The above issues are made worse by the arthritus in my 70 year old thumbs. My gripping strength is a little low.
I'm approaching this issue on several fronts, and expect to be successful.
I am able to get a better grip on the slide when wearing gloves.
I ordered a "Slide Spider", skateboard strips for the slide serrations. Also a 11# recoil spring.
I cock the hammer prior to racking, that also makes it easier.
I don't have to "slingshot" the slide to chamber a round, the slide release is very effective for that.
I'm pretty sure these things will solve my "racking" issue.
Selling the Shadow 2 is not on the table.
