What do you think?

All I was saying is that the difference between pistol calibers is a wash. They are all underpowered to begin with being pistol rounds

I've just been busy today and haven't been on the board.

You're right on this one, Ace. I, like most other handgun shooters on this board, realize that all 3 accomplish the same task with very very minute differences in terminal performance. If someone chooses to shoot a 40 or 45 instead of a 9mm they won't necessarily be undergunned.

But since they all pretty much do the same thing (when choosing premium JHP rounds) I choose 9mm because I get the most ammo in my magazine and it's the easiest to control. I increase my chances of hitting the target and I increase my chances of hitting the target multiple times. And since I know handguns are simply a compromise compared to a rifle or shotgun, I would rather have as much ammo at my disposal as possible.

How many rounds will it take to end the fight? 6? 10? 12? 17? I have no idea - that's why I like having as many as possible.

I've never heard a real account of a defensive shooting and heard the person say "I really wish I had fewer rounds."

People who believe what they see in Hollywood think one handgun round (from the big 3) is sufficient. But we know better than that.

So when discussing the big 3, I'll take the 9mm.

Anyone know where I can find a nice .40 S&W upper for an AR build?

Asking for a friend. TIA.

I think QC10 makes one. The upper is all the same, but barrel and bolt are different.

I prefer the power of the 40 and 45 over the 9mm if my life is on the line.

I prefer 9 for target shooting and for my recoil sensitive wife.

The FBI has proven that the additional power is minimal and even with the additional training, their agents need the additional rounds vs "power".

For the life of me, I cannot figure out how so many posters know more than the FBI when it comes to ballistics.

This may be a dumb question, but it's a serious one. Do you think the fbi is buying more 9mm to save money on ammo as well as a whole?

I think I've dispatched more living things with my handguns than the average fbi agent has.

Then again, I prefer rounds that the "experts" say don't work. But if it'll dispatch a male hog, it'll kill a human.

Two of my exes are trauma surgeons, their worst handgun rounds they have worked on were .22 hollowpoints of all things.

One of my friends was a pathologist and county medical examiner, he said the same thing.

I have a dozen 9,s and carry a 40 for work daily. I can shoot truck nuts at 50 yds with a 9 but not with a 40. I cant shoot a 40 worth a frick. That being said Im a police firearms instructor with 20 plus years experience. A master revolver champion and an armorer for Glock, Colt, Smith & Wesson, Remington and Beretta. The 9/40 debate boils down to Glock trigger pull and striker fired accuracy problems. Ballistically better than a 9 but only worth the moderate results if out of a quality firearm and not some polymer piece of shite.
Personally Id go with a 9 over a 40 but 45 acp is good also. However in a sig the 40 is manageable.

That's because you aren't honestly assessing the responses as well as the complete picture of what the FBI decided with the 9mm. Your bias and unwillingness to examine what is actually being posted is your problem and nobody but you can correct that. You are focusing on ballistics to the exclusion of everything else, not even the FBI did that but you are trying to make it seem like they did. I've read that paper and several others related to it, you should do the same.

That's bc surgeons don't need to operate on dead people.

Cute.

Best one I ever heard from her was a kid who was shot 7x with .45 and stumbled into the emergency room. So take it or leave it.

Everyone screams that lightweight rounds (not the purely polymer and epoxy junk) don't work. But in my experience a handgun round that enters, expands to max size in a very short distance, and then splits into 4 or more chunks creates a more catastrophic wound channel before creating a series of smaller exit wounds. It may not show that large exit wound, but the internal damage is more extensive.

I'm fine with people disagreeing, but a boar hog is tougher than any man.

You're leaving out that the killers in Miami were hit and didn't go down right away. They were also combat vets. Didn't freak when they were hit. In some ways, they were better trained than the agents.

Agents also got nailed trying to reload revolvers.
