For the last few days I have read the response's to the article. I have carried a S&W 19-3 as a police chief, a S&W 66-3, a Sig semi in 40 s&w and a Glock 22 as a state law enforcement officer. I have been shot at, (hit-cut) and have shot at people.
When I started we shot from 50 yards to the 1 yard line. Then it went to the 25 yard to the 1 yard line. Now it's even shorter in distance with less ammo expended. As a firearms instructor I will say this, law enforcement does not shoot enough. Accuracy is paramount and the most important rule of gun safety. If you cannot hit what you are shooting at you are unsafe, period. I have seen folks shot with a .44 mag, torso hit and lived. Head shot .25 auto point blank ( muzzle inches from the back of head) she was walking and talking when we arrived, lived. Caliber is important to a point. Can you put it where it needs to go. Let's look at the weapons of a couple of gunfighters, Bill Hickock- colt navy .36 caliber. Bill Jordan Model various .38 and .357 revolvers finally the model 19 he fought so hard to have S&W make, as well as a 1911 and others. I prefer the .40 S&W and .45 ACP but that's me. I own high capacity handguns. They are great I just do not need 30 rounds of ammo to go to town and back. Shot placement is important, screwing your brain and a#$hole down tight and focusing on the situation is a requirement to survival. That's why good instructors teach and correct shooting problems, as well as do things to rattle your mind set while practicing. Because it's even more unsettling in real life, it's up to person to become proficient with what caliber they choose to carry. In the end hell I don't know. In WW I, the roaring 20's WW II, Korea, Vietnam and Afghanistan, a lot of folks have been killed with 32's, 38's, 9mm's, 44-40's, 38-40's, 44's, 45LC and 45ACP's. It depends on what you have and can shoot safely (accurately). Accuracy matters. Everyone that has commented at least has given some thought to their situation, that is important as there are no participation trophies in real life that you want except to live , to survive.
Ok I will get down off my soapbox and shut up. Thank, Ethan.
