Having an advantage of being close to G&R, I wasted no time to get my M&P in on this offering. I've always had an issue with accuracy being both this auto and me and my old eyes. Grant did a smack up job on this going to attempt to get to the range tomorrow to give it a run.
Out of several stock m&p barrel specimens measured, the (hood?) averages were around and very close to about 1.219, mine came in the shortest in the group at about 1.215. Not that tight. That might explain some of the misses / big groups at 25 yards. Have to say, this storm barrel locks up tight.
