Had a great day out on the range plinking some steel today. Here are both the M&P40 Core and SR9c. Both have very smooth recoil impulses, although I did happen to be using reloaded ammo.
As for the M&P, I installed a forward set sear and trigger kit from Apex. This absolutely beats the hell out of the Pro Series trigger from S&W. My shooting improved with it immensely. I cannot wait to throw an RMR on it!
You can also get a good view of the sights on both guns. I happen to prefer the taller sights on the CORE as opposed to the standard M&P sights. And the fiber optics on my Ruger are an amazing improvement over the former tiny sights.
Enjoy! M&P40 Core SR9c
