Is that movement during lockup or with the slide pulled back slightly?
Also, Randy, with the SDI apex barrel, what is the estimated wear before the hood/lugs don't have that tight fit any longer?
Not sure if I worded that question correctly.
The fit between the slide and barrel hood is not as important as the fit between the barrel bottom lug and the locking block. The SDI should maintain lock up stability for at least 25,000 rounds. The nice thing about the M&P is that you can replace the locking blocks to tighten up the lock up again.
