What’s one millimeter more? 9mm vs 10mm… Number’s wise, it might seem minor at best, like having $9 vs $10, but as far as ammunition calibers are concerned, that increase of one millimeter makes all the difference.

The average grain weight of a 9mm bullet is around 115 grains, and the average 10mm is around 180 grains. Making the 10mm bullet 63% heavier of a round over the 9mm, that one digit millimeter difference, is really the equivalent of 63% more mass.


Now, you might also be familiar with .45 ACP, a long-standing low velocity, high powered round. Surprisingly enough, the 10mm and the .45 look an awful lot alike when you put them side by side, they’ll pack a similar punch but perform in different ways. The muzzle velocity of .45 is 840 feet per second, versus the 10mm’s 1008 feet per second. With greater muzzle velocity also comes added benefits, such as flatter shooting and better accuracy at further range. Advantages like these are why the 10mm caliber has become widely regarded as the ideal round for personal protection in the backcountry.

The new M&P®10mm M2.0™ pistol was designed to match the M&P®45 M2.0™ pistol frame size, with new aggressive front serrations traditionally only seen on law enforcement M&P® firearms. Working your way back on the slide, you’ll notice that the 10mm comes standard with the C.O.R.E.™ (Competition Optics Ready Equipment) slide and optics mounting kit. But let’s not forget one of the most recognizable changes to the M&P®10mm M2.0™ pistol, the new flat face trigger geometry. Following the success of the Shield™ Plus pistol flat face trigger, the 10mm is the first in the M2.0™ pistol lineup to feature a newly updated trigger.

With a capacity of 15+1, backcountry bears and cougars won’t stand a chance against your M&P®10mm M2.0™ pistol. You can now rest assured that your ideal backcountry sidearm will have your covered.
