Forgive me if someone already suggested it but I didnt read the whole thread.

But just get all of them :wink: Thats basically what I have done with the exception of the gap (which I will never own) I prefer to shoot the 357sig mostly and use the 40 for a loaner gun and hardly ever shoot my 9mm. I keep several cases of ammo each

Yeah it made me remember why I should have a rifle in my trunk.

The wounding mechanisms of a handgun bullet are 2 fold. Penetration and the permanent cavity. If it doesn't effect one of those 2 things it has no effect. A .45ACP making a slightly bigger dent in clay if anything will make a slightly bigger bruise on a human body. It won't knock them down, and in the middle of a fight they might not even know they've been shot.

Bullets kill by making a hole in the body and allowing the blood to drain out, or by disrupting the central nervous system. To allow the blood to drain out of the body quickly numerous holes in vital structures are required. Even having a bad guys heart completely destroyed he may be ambulatory for around 12 seconds(+/- 2 I can't remember and it's late). The only reliable way to effect a one hit stop involves a complete disruption of the central nervous system. Normally passing through the upper spinal column or the lower brain. Frontal lobe shots (middle of forehead) may or may not have the desired effect of immediately stopping the bad guy. Ergo on a failure to stop drill or a set-up head shot. I would aim for the eye. It's a distinct point to aim for, as well as being a soft target to insure the bullet enters into the brain instead of bouncing off the skull.

Rifles on the other hand had 2 more mechanisms of wounding temporary cavity (note this is only useful in rifles. The temp cavity from pistols has been proven to have 0 effect) and fragmentation.

While the Russian 7.62x39 FMJ, 5.45x39 FMJ and the 7.62NAT0 FMJ do not provide reliable fragmentation and generally crushing a relatively clean path through the body. This limits their overall effectiveness.

5.56NATO on the other hand upon entering the body rotates about 90 degree's and proceeds to split and the crimp. Fragmenting very reliably and producing a nice permanent cavity. This occurs with both M193 and M855 although the lighter 55grain round provides the desired fragmentation effect farther out. OTOH the 62 grain round provides better penetration of hard and soft cover.

.308 JSP and it's effects on the human body are truly amazing producing awesome permanent wound cavities.

Here are some pictures

9mm = euro cop round

9 blows. Dated and poor round.
Don't be swayed by it's popularity. It's a hole maker, not a BG stopper.
Over penetrates with inadequate energy.
You made the right choice.
Keep dreaming. The 9mm does nto overpenetrate except in a FMJ, whic only a moron would use for defense unless desperate or required to by international treaty. Modern 9mm JHPs do NOT ovepentrate. The fact is both are equaly innefective (as are all handguns bullets,you need a rifle or shotgun to really stop people) in themselves and bullet placement is everything. I would rather put three 9mm rounds on target in the amount of time it takes you to do two .40. Due to lighter recoil impulse the 9mm is faster back on target and due to speedier bullet is more accurate (less flight time) and has higher expansion probability. In addition the pressure pulse of a 9mm is not as harsh on a barrel and the frame will wear less from recoil impulse over time. I know one entire academy whose staff went from G22s to G19s as the gun lasts longer and it makes for faster and more accurate shooting.

That being said I used to own a XD-40 and got rid of it. It just did not measure up to a XD-9 in accuracy and speed. Right now I get .25 second split times shooting the 9mm in controled, aimed, rapid fire at 10 yards doing Bill Drills. I know that the recoil impulse in a XD-40 would increase this a good bit.

If you're smart about picking your carry round there's not much difference as far as stopping BG's. The best rounds in .45acp, .357mag. and 9mm are all within a point or two of 90%.

TJP : Picked up a new XD-40 on monday...

Wish I had gone with the XD-9 just due to the higher cost/lesser availability of the .40 vs. the 9mm. And seems like not a lot of difference in stopping power, IMO.


Around here, for practice target ammo, nothing but 180 gr. FMJ and can't find the 155-165 gr. in WWB, UMC, or PMC. Or affordable to me right now, JHP. No Bonus Packs, either, lol.

I know, I should have put a little more time in researching ammo for my new gun. Hopefully, I'll enjoy shooting the .40 more!

Anyone else?
I know what you mean, and you were RIGHT , look what happened to the .40 now, notice the popularity of the 40 has gone way down since your original post back in 2005? the 40 is pretty much dead now, most LE agencies have switched back to 9mm

I always stick with the more common calibers like 9mm or 45 acp , makes it easier to stock up on more common calibers and keep it simple

with 9mm you will buy more ammo since it's more economical, and you will train more often, and become more proficient with it, you cant go wrong with the XD9

I see 40 S&W firearms in the local gun stores all the time but I always pass on them because I rather have it in 9mm

the 40 cal handguns are usually the last ones to sell, the 9mm's sell out much faster.

Nope. Just bought a couple FNS .40's. $299.99 each, brand new. The 9MM versions are about twice as much.

Live in a ban state? Even the little FNS .40 Compact holds 10 rounds in the magazine. I'll take 10 rounds of .40 over 10 rounds of 9MM.

I just bought 3 boxes of .40 S&W 180 grain hollow points (Winchester) for $20.97 for 50 rounds. I should have bought the 2 boxes of 9MM 147 grain hollow points (Winchester) for $21.97 but I was so busy picking out some test ammo of various brands/bullet weights to try out in the new FNS pistols I forgot to tell the clerk I wanted the 9MM hollow points, too.

I have no idea why the 9MM Winchester hollow points are more than the .40 S&W Winchester hollow points.

Yeah, I know I can the target practice 9MM ammo cheaper than the target practice .40.

Hey, once all those LE departments/agencies switch over to 9MM do you think it will stay cheap/available?

What's the justification for .40 costing more? More lead? More powder? More brass in the case? If that's the real reason why does .380 cost more than .40 or 9MM?

Stop it. This thread was started when Obama was in his first term.

One of these days a thread will be reincarnated that talks about when 41mag was a popular round.

Love mine ...
