Now that we’ve pivoted to ammunition…
I was a “bigger is better” guy before the nineties, when ammunition got better, I got into a hobby that put me in proximity to lots of LE shooters, and I applied actual research to my decision.
The most important aspect of any lethal encounter is my signature line on all the guns forums I participated in for a long time:
“You cannot miss fast enough to win a gunfight”.
This applies to the weapon, mode of carry, shooter’s ability, and ammunition.
Whatever gun you can shoot best, have confidence in, and will have with you when you need it is the best for you, period.
Decades of research show the stopping power of 9, 40, 45 to be equal statistically when placed in the vitals.
The real surprise is that with a handgun, the vast minority of wounds are fatal.
Learn to shoot well, with your “off” hand as much as your dominant hand, and work on mindset and application of skills.
If you have to shoot, shoot until the threat stops.
Plaintiff attorney: “why did you shoot my client eight times?”
A: “because he was still presenting a threat that made me fear for my life after I shot him seven times”.
To quote the great Clint Smith, “handguns put holes in things, rifles put holes through things, and shotguns rip chunks of sh*t off and throw them on the floor”.
Any successful job is achieved by considering the job and picking the best tool you have at hand for that job.
Revo vs auto? Same stuff as cob vs meer.
