Sounds like some of the shops are nearly as clueless as some of the legislators. 9mm equal to the effectiveness of a .45 or .40? The larger the gun the more velocity of the round? Maybe the writer misunderstood some of the info provided. Barrel length/velocity.
“The bigger the gun, the higher the velocity of the round”.
Really? Really are the reporters that clueless? Size of the gun has nothing to do with velocity. It’s the bullet and load.
Wonder if they also told her that the loud bang is from the bullet breaking the sound barrier.
With modern hollow points, good ones expand 50% such as my Hornady critical defense.
That means a 9mm (.355) is actually .5325, larger than .45 ACP.
