Today I acquired an M&P 2.0 9mm 4.25" barreled "full size" handgun. I wanted to test the pistol for accuracy so I set up some NRA slowfire bullseye targets at 25 yards. Temperature was approximately 80 degrees, 5-10 mph quartering headwind, sunny, 500 feet above sea level. The M&P had the stock sights. I am certainly not the most talented handgun shooter in the world, having put downrage only somewhere in the neighborhood of 30-40k rounds in my time. To compensate for that, I used a handgun that has a reputation for accuracy, the Heckler and Koch P30L in .40 S&W w/ the Light LEM trigger, as a "control", by which to measure the M&P's performance. The H&K has truglo night sights. I shot 5x 5 shot groups with the S&W, then shot 5x 5 shot groups with the P30L, then shot 5x more 5 shot groups with the S&W to establish a rough accuracy baseline for the pistol (50 rounds S&W, 25 rounds HK). My technique is to throw out the smallest and largest groups for each pistol to try and eliminate the role of luck and then average the remaining group sizes. The S&W used Federal P9HST4 147gr +p and the HK used P40HST1 180gr ammunition. Shooting position was resting on sandbags from a bench, shooter seated (distance 25 yards as stated).
The results were as follows:
S&W M&P 2.0 9mm = 3.3256" average 5 shot group
H&K P30L = 3.6197" average 5 shot group
Here are the targets for those interested. Maybe the S&W benefited slightly from my method because it had a 6" group thrown out, but likewise the HK had a 5" group thrown out. There was no cherry picking, all fired groups are displayed. I did fire a cold bore sight off target with both pistols to warm them up before testing. I fired a total of 330 rounds of P9HST4 through the S&W with no malfunctions doing other drills after this test. I will commence from here with a 2000 round challenge as I am pleased with it thus far. The stock rear sight seems like it might need to be drifted slightly to the right, however I expect to be installing trijicon night sights on it soon enough so probably won't bother. The trigger pull weight on the M&P 2.0 measures a consistent 5.5 pounds.
S&W M&P 2.0 9mm, groups 2 and 8 thrown out, remainder averaged
HK P30L 40 S&W Light LEM - groups 1 & 4 thrown out, remainder averaged
