Yet again, these anti-gun legislators are proving that they know very little about firearms. 7 round magazine....hmmm, I can only think of a few handguns that currently carry only 7 rounds. They tend to be larger caliber, like the .45 caliber 1911. So, now that these law-abiding criminals are restricted to 8 rounds, they're using larger and more powerful ammunition.
Few people seem to realize that one of the reasons many police departments chose 9mm pistols starting in the 80's, is because of that particular round's ballistics (FMJ rounds). Its high velocity and small frontal cross section give it excellent penetration, to the point that most shots into a human analog at self-defense distances are "through and through". While the bullet causes damage, its wound cavity is relatively small and the bullet tends to exit the body on a "straight line" from the point of entry. Compared to several other pistol calibers, the 9mm can validly be, and is by many, considered less-lethal.
The .45, on the other hand, is a flying dump truck compared to the 9mm. Even in FMJ, the .45's blunt nose and lower relative velocity give it great knockdown power, while tending to tumble through the body, creating a very large wound cavity and exiting in places other than directly across from the point of entry.
Good job NY. Even using the anti-gun lobby's model of gun crime, in which restricting the rights of those who follow the law will somehow influence those who do not, they're effectively promoting the use of larger and more lethal calibers.
Unintended consequences, the hallmark of logically flacid gun legislation.
