"Better" is a meaningless term in this question. You must specify the end use of the weapon.
H&K claims their pistols to be the most accurate out of the box. This has been disputed.
Either the SIG or S&W
For the AVERAGE 9mm pistol, not very well. The M9 pistol is considered to have an effective range of 50 meters. There ARE 9mm pistols and shooters that are accurate to 100 yards- but not an everyday affair.
"Best" is too subjective to define for a hand gun. The biggest, the most practical, the most accurate, the most concealable, and the most durable pistols are all totally different guns. Two very popular models are the 9mm Glock and .45 caliber 1911. Both are used extensively by law enforcement and military personnel.
Most likely it is a Hi-Power if it is a 9mm.
Taurus made several 9mm handguns. Which model did you have in mind?
9mm means the firearm shoots a bullet that is about 9 millimeters wide.
Most likely a 9mm with a suppressor
9x19mm, also known as the 9mm Parabellum or 9mm Luger.
a 9mm is not very powerful and i have one and a can shoot it and hit the target at maybe 150 to 200 feet if you want to be accurate at all
