Just noticed a very small detail that was added to the M&P that you don’t typically see in a pistol and definitely not in a polymer one. They’ve added a slight crown to the barrel which is widely known to improve accuracy. Here’s a description of what a barrel crown is and it’s purpose :
The primary purpose of a firearm muzzle crown is to provide propellant gases a resistance free path away from all parts of the projectile as it exits the bore of the barrel. The secondary purpose is to protect the bore from damage caused by misuse. The third purpose is for good looks which is always achieved when the primary purpose is satisfied.
Good Job Smith and Wesson! I’m liking this gun more and more.
