Just killing Thanksgiving morning fellas and looking over the posts in this forum:)

FWIW: Some of you are obsessing over caliber choice to the point where it is ridiculous.

I am a retired LEO from NY. I did 6 years in patrol and 18 in SWAT. During that time I have seen for myself or was present for the aftermath of probably hundreds of shootings with all types of weapons from handguns up to 223 and 308 rifles. I remember seeing a guy hit dead center mass with a 22lr die within a minute, yet another person hit in the same place with a JHP 357mag (was still standing when I got there) tell me what happened, who shot him, etc and survive. I also saw a guy hit with a 223 go down after getting hit in the left torso...lose a lung but survived too. I remember another time when a suspect was struck in the arm with a single 9mm round die from a heart attack but yet another guy was riddled with MP5 9mm rounds died only after being shot in the head with a 308 round.

I guess that my point is this: don't obsess over which caliber is best because I don't think that it matters much because bodies do strange things. There isn't a damm bit of difference between getting shot in the same place by a 9mm, 40, or 45 round with good/modern bullets...that's for damm sure.

With that in mind, I would carry a minimum of a 38/9mm in a gun that I shoot well.

FWIW: I ONLY carry a G19 with Speer 124gr Gold Dots because it was my duty weapon and I am 1,000% sure that the G19 is the best weapon for me. I like the fact that it holds 16 rounds which I would rather have than 8 with a 45ACP. I had a G23 for a while but I sold it because I didn't like the recoil and increased muzzle blast of the 40cal for an insignificant/irrelevant increase in "stopping power."

Just my 2cents:)
