Sorry, haven't checked the forum in a while. No problems swapping grips. I did keep the s&w hex screw vs. the magpul flat head screw. Added a washer because the hex head was a little smaller than the flat head.

Got the Sport pretty much tricked out how I want it. Did swap out the stock for a Magpul locking stock. Just need to finish fitting the DPMS wedge and she should be rock solid and no wobbles.

Have to find time to go to the range now and break the barrel in.
