9mm vs .40

[horsepwr]

TweetSo I was told by the gun shop owner that I go to that the 9mm and .40S&W perform too similar to tell a difference. He served 22yrs training state officers how to handle their weapons. He said he ran ballistics tests, etc, etc...and he said when the 2 are tested...shot through leathers, car doors, seats, glass...they perform identical. He said the only thing you get different from the .40 is a bit more recoil, and slightly dirier blast. I guess he meant gun powder.??? obviously.
But, a little more powder, and a slightly bigger ball...it must even out.

TweetI do 9mm and 45's i don't see much of a need for the 40 but some people love them and that is their right.

TweetI'm right with ya on that. I'll step on to the .45 from the 9mm.

TweetYou said it. 9mm ammo is more readily available than 40cal. That's why it make no sense to go 40 unless you just makes you think your better by saying it. 9mm and 45 are the only ways to go

I think he is correct. As far as stopping power, very little diffrence. For some reason local PD's went to the 40 and the only diffrence is 2.5 times the price in ammo.

Tweeti have about evey caliber hand gun and with the 40 my shots tend to jump around more but with the 9mm and 45 they r dead on the 40 even jumps around more than my 357 and 44. so i would not recommend a 40

Tweeti love my .40. but i also love my 9mm. its a matter of preference. there would be no point in having 2 glocks 1in 9 and the other in 40. but 2 different guns is totally cool. if u want to shoot sig 9 and a glock 40 both guns are going to handle differently anyways. but there is a big dif. in ammo. but if u can afford to shoot 357 and 44 ... u must be doing alright economically anyways.

That's pretty much where I am with it. With Glock. Them being interchangeable, you can have a really good system once you've chosen your caliber. When I say "system", take me for instance. I'm going to go with a 9mm in Glock for a few reasons, but by system, I can get a G26, add a +2 base plate to the mag. Now I have a great CC piece with better than average CC capacity. Heck, with Glock's mags being accepted by any other model i the same caliber. I could stick a G19 15rd mag in there, slide the aftermarket sleeve over it to snug up the mag and fill that void, and the concealability and comfort really doesn't suffer any.
But the Glock system I'm going for is the G26 & G17. Then I'll have a good system of the same caliber so if the shyt ever really hit the fan, there's no doubt about ammo with which one. Which ammo with which gun. And I dig the 30rd mags for the 9mm. Keep a couple of those full at the house with the G17.
