Shot the M&P with the stock recoil spring and below are the best results. All shooting was done at 15 yards.

WWB 115gr.

To be honest it's nothing special, but it's way better than what I was getting with the old barrel. I went from a 10" group at 15 yards to what you see above. I've already sent in the gun twice and got a barrel on the second trip so I'm not going to bother with it again since I think this is as good as it's going to get. I'll just throw it in the back of the safe and wait for Apex.

I'll throw the stiffer recoil spring back in there next range trip but that won't be for awhile. All I've been doing with this gun is using up ammo for test purposes only and it's time to shoot my other 9mms until Apex comes up with something to make it somewhat decent.
