NOOOOOO 9mm, Look there is a reason 95% of law enforcement no longer carry 9mm side arms! They have HORRIBLE knock down power! If you are in a situation that requires you to pull the trigger do you want a gun that will knock an attacker on their [censored] with one shot? or a pea shooter that unless you hit them in the heart or the head will only piss them off! go with a compact Smith & Wesson 8 shot 45acp.

Where did you hear this? Here's what wikipedia says.....................

http://en.wikipedia.org/wiki/9x19mm_Parabellum

The 9x19mm Parabellum (abbreviated 9mm, 9x19mm or 9x19) cartridge was designed by Georg Luger and introduced in 1902 by the German weapons manufacturer Deutsche Waffen und Munitionsfabriken (DWM) for their Luger semi-automatic pistol.[5] For this reason, it is commonly called the 9mm Luger cartridge, differentiating it from the also-popular 9mm Makarov and 9mm Browning cartridges.

The book Cartridges of the World stated in 2006, the 9x19mm Parabellum is "the world's most popular and widely used military handgun cartridge."[6]

The name Parabellum is derived from the Latin: Si vis pacem, para bellum ("If you seek peace, prepare for war"), which was the motto of DWM.

In addition to being used by over 60% of police in the U.S., Newsweek credits 9x19 pistol sales with making semi-automatic pistols more popular than revolvers.[7] The popularity of this cartridge can be attributed to the widely held conviction that it is highly effective in police and self-defense use.[8] This cartridge has been shown capable of imparting remote wounding effects known as hydrostatic shock

good quality 9 is extremely effective
almost every firearms trainer these days has switched to 9mm due to the effectiveness of current ammo, fast followup shots and affordable ammo to practice with

self defense is NOT hunting where we believe in the ethical "one shot"

I can put 4-5 shots from a 9 faster and in a tighter group that I can put 2-3 from a 45 or a 40..

Yeah and your going to need 4 plus shots to bring him down

"2. I do mean something in a 9mm. Don't want to do a caliber argument here either."

and the first rattle out of the box...the caliber argument!!!

Hooray for the internet. 1st reply and 1/2 the thread is specifically the subject the OP did not want to discuss. Unfortunately there are just too few gun forum threads on the 9mm vs .45 already so this one has to host further discussion on this dead horse topic from hell.

To the OP,

I have a PM9 and find it to be an excellent carry gun, but it really only works for pocket carry in cargo shorts or khakis. In jeans it's still too big for my taste. I finally just gave up and carry a Kahr P380 in the pocket almost exclusively.

You will if you shoot like most cops do in the headlines we see. One properly aimed shot will kill a human all day long, we kill metric tons of hogs with subsonic 9mm with one shot from a SBR'ed Colt AR.
