For the average shot or new shooter 9mm it is a choice due to lower recoil. I have 45s and 9s and sold my 40 SW P229.
My HK45C has less recoil then P229 in 40. It is more to the shooter to choose. I like 45 but 9mm is good also for SD.
Proper shot placement and follow up shots will help more then any large handgun caliber.
9mm practice cost less and with today's ammo cost this can make more people to convert from 45, 40 to 9mm.
I do believe it.
Safe shooting, Vodek
rent a 9mm and 40cal and shoot the 9mm then shoot the 40 shoot the 9 and then shoot the 40 back to back round for round and then you will see what you like best.
A 9mm is great. There are a ton of bullet options in different weights and power configurations.
A 40cal usually take a little more steel to support the slighly larger recoil generated by the round. Im not ballistics specialist but I believe that if you had to get a stick fight the 9mm would be like a 2x4 hitting you fast and the 40cal would be more like a 4x4 hitting harder and a little bit slower.
More metal in the slug may equate to more stopping power and penetration in most cases. Im not ballistics specialist by anymeans.
I refuse to carry a 9mm. I have a 40cal and I have 165gr Federal Hydrashok rounds in it. I carry a walther PPS as my primary. I just secured a Kimber tactical pro II .45acp which will be my new main defense platform.
I refuse to let my wife carry anything less than her 380acp which is an underpowered 9mm. Her main carry is a 9mm SKKY CPX1. She loves it. Recoil is nice. Round prices right now avg 12-14 a box of ball. 40cal is about 15 a box now. So the price difference at the end of the day is negligible in my opinion.
Gotta find what works for you.
If this is your 1 and only handgun, I would guess 9mm. Increased capacity, target ammo will price right, and if you have concerns for 2 legged SD, 9mm +P is an option.
Much has been written regarding the 40 cal having greater muzzle energy and therefore possibly greater one-shot stopping power. I believe that the best caliber is the one (9mm or larger) with which one can rapidly deliver 2 or 3 COM hits out of a string of 5 or 6 shots. I can do that with my XD(m)9 and PM9 in just a few seconds, but I have less confidence in my ability with the .40 or 45 ACP. I am a little guy and an average shot at best. Your circumstances may vary.
Bottom line is whichever you shoot the best!
Both are proven cartridges and both have proven defensive loads for just about whatever gun they are running through.
Whatever one person says about one caliber won't mean jack to the next guy posting about the other caliber.
Both calibers work on the street, both calibers work with law enforcement and both work for the bad guys.
I personally know LEO's who've killed bad guys with both rounds. Interestingly, I know one trooper who shot a guy he was hand-2-hand with in a fight at the side of the road. Shot the guy 3 times in chest & abdomen with muzzle pressed into BG's body with his Glock-22 (.40) and the fight wasn't done until he shot him a 4th time in the head. I also know one LEO who dropped a guy with two 9mm rounds COM at about 8 feet, so there ya go.
Get which ever one you shoot the best and call it good.

Thanks for all the replies. I carried a 9mm as plain clothes duty weapon for many years and then retired and carried nothing for a very long time but now because of the world situation and the legal authority to carry in al 50 states thought I would look into one of the compacts and also at the 40 which wasn't around when I was working. I have had my share of duty related shootings being from Chicago and working the ghetto the whole time but now I don't feel the need to have to protect myself over about 30 ft which a compact is well suited for. I think I will stay with the 9mm for ease of keeping the shots tight and on target. For the same reason I am looking at the Walther P99C in DA/SA which also makes keeping on target easier. Didn't really think I would carry again but how the world has changed.
I carry a kahr P9 because I have small hands and it fits great. I used to have a S&W .40 but the double stack was just too much grip. I also have a Kimber .45 that also feels great. For me, the smaller 9mm is more comfortable to carry so that is the one I do carry. If 8 shots of Ranger SXT out of my 9mm isn't enough, a bigger pistol probably wouldn't help anyways.

I've regressed over the years. I started carrying with either a .44 Spl or a .45 ACP thanks mostly to Mr.Keith and Col. Cooper. Then I went with the .40 for about 14 years. Last 3 and I'm toting a 9mm. I'm more than comfortable with it. Truth is, they are all pipsqueaks compared to even small bore rifles or even a 20 ga. shotgun. If I do my part, the caliber isn't going to matter much.
Hey all, I have 9mm's. The mags are 17 rounds but if I can't hit a vitial part of the body then it don't matter if I have 40 round mags.
No matter .40 or 9mm one must pratices to stay sharp. And the 9mm is cheaper for me to pratice with.

Thankfully I can abstain from any caliber debate since I tweaked my wrist in a bike accident. The largest caliber I can carry and shoot comfortably is 9mm.

This debate will never end. I am very comfortable with 9mm. THe most important thing to do is carry. Shot placement, quality ammo, and quality gun are what counts. For anyone that wants to doubt a 9mm, I suppose you will have no problem coming over and letting me fire a few rounds at you COM?
Men look out for themselves; real men look out for others!
Comparing the two rounds in an open forum is like telling a liberal that Global Warming is man made which is the truth btw!!
I have shot alot of different rounds both Civi and Military and I have found that I equally like both the 45 and 40 cal. I have both calibers now and I can pick and choose. I dont care either way as both rounds will knock the wind out of most any thug that wants to threaten me or family.
However I have acclimated in extremely short order to the 45 1911.
There is something about my Kimber .45 that just screams FEAR and DEATH when an assailant looks down that huge steel tube and see's the shiny copper hydrashok looking back at em. You cant see the bullet looking back at you in a 9mm.
Yeah I used the mirror, no I didnt look down the barrel directly lol...
