I read this thread some time ago and tried the V-Crown 9mm 124 gr bullets in a couple of M&P EZ's along with Sierra 90gr JHP's, Hornady 115 XTP's and Remington 115 FMJ's. The difference in those pistols was amazing. At 7 yards the groups went from poor buckshot groups to very tight 2" groups for 3 different shooters with the short 3.675" barrels. We fired about 150 rounds between the 2 pistols. I had loaded 50 rounds each of the 90's, 115's and 124's. the FMJ's were several magazines from a Remington factory tub.
