9 mm vs. .40 accuracy?

I fail to see what technique has to do with shooting two guns with the same frame and trigger, with the only difference being the cartridge.

Proper technique executed correctly will allow you to shoot a .45 just as fast as a 9mm.

That's what technique has to do with it.

Now I shoot a .45 and a 9mm just fine. I have no inclination to play with a .40 anymore at all.

SIG P229 40 s&w "is the cats meow " if you have and understand basic marksman
skills you can shoot ALL platforms well.Practice practice and practice and its all good.

I like the .40, although it certainly is more "gun" to handle than a 9mm. One week I shot a match with a German P226 in 9mm while my P229 (.40) was having the SRT installed. Less muzzle flip for sure. I have found that you can *almost* ignore that by pressing the second shot quickly. Not quite as quick as double tap, but not waiting for another sight picture either.

It's like sandbagging!

Accuracy-wise, I do not see any degradation due to caliber. Some people do not shoot .40 well. It's a tougher one to learn.

In all my years of perusing gun forums:

I've read that 9mm is inherently more accurate than .40
I've read that .40 is just as accurate as 9mm
I've never read that .40 is more accurate than 9mm

Absorb those three sentences and come to your own conclusion.

Why? The sight picture is there, you just have to see faster.

I don't own a 40 semi auto but of the 9 mm pistols I own I shoot my CZ 75 best followed by a 92fs and a 225 comes in last. I have found that a standard barrel in 9 mm with a 1 in 10 twist won't shoot my cast bullets well,but a Bar Sto with a 1 in 16 twist aftermarket barrel does quite well in my 92fs with cast bullets.

I think the better question to ask is which is more accurate with a particular set of components you plan on using. There is not going to be alot of difference if you wanna use cheap plated bullets, mixed-headstamp brass, and whatever powder.

With that said, I do not think the .40 has been developed to it's potential. While there are some accurate platforms out there, they are not optimized for the round in the same sense 9mm target pistols are.

Buck13,
I would recommend to address accuracy/practice with 22LR caliber instead of 9mm/40sw.
You can have a lot of practice for a reasonable price.
