40cal vs. 9mm

What are some of the differences good or bad between these two guns. (which one is bigger, has more knockdown, less recoil, more accurate, etc....)

Bucky10,

.40cal>10mm
9mm>.36cal
There's only .004 different,but if you go to .50cal> 12.5mm.
IMHO,High Desert Eagle in .50cal has more recoil, but more knockdown power.

I'd like to respectfully disagree with you Rebel Hog.

The 9mm Luger has a nominal bore diameter of .355" for jacketed bullets. The .40S&W's nominal bore is .400", for a difference of .045", which is significant. The .40S&W is obviously larger diameter, but they both fit in the same size magazines, with the 9mm having a few more rounds capacity in a given sized magazine (now that the retarded AWB has expired and full capacity mags are legal again).

To answer Bucky's question about "knockdown power." With premium defensive JHP loads, both are very similar with the .40S&W having a slight advantage. Accuracy for both is more dependant on the gun than the cartridge. The .40S&W has a bit more recoil, but generally less than the .45ACP in my experience.

Drift, I was THOUGHTING when I should have been THINKING...Thanks!

That is exactly what I was looking at was the .40cal S&W or a glok 9mm and really the glok 9mm is more exspensive(my guess is name brand) but really the ammo for both of them are about the exact same. Both are very nice guns. I was just wanting a gun for plincking and taking to the woods with me in the off/scouting season for security or whatever.

For the above use, get a good quality 357mag. revolver (stainless), such as the
Ruger Security-Six or current model, a GP100. 4" barrel or 6".

I agree that the revolver is probably your solution. I always am amused when I hear the argument over what's better, the .40 or 9mm. I own lots of different caliber handguns and I carry a 9mm for personal protection. My response to the nay sayers is that I'll ruin their day with my 9mm just as bad as a .40.

Oh yea, have you tried it? I never get amused about any question I can't answer with first hand knowledge.

Bigcountry, I'll only say that I've been in Law Enforcement or the Military all my adult life. I feel confident in what I said.

Well shoot a bunch of my family can say that. But they really don't know much about killing.
