The accuracy of a 9mm cartidge.....

Cartridges are not accurate or inaccurate. Barrels are. Once the round is chambered and held in a machine rest all that's left is the barrel. Now if we're talking long range rifles at 700 yards then the bullet can make a difference.
 
I agree with Drail. The human factor has to be taken out of the equation to determine accuracy, which in my opinion involves identical barrels and a machine rest for each caliber. Until that is satisfied I don't see how true accuracy comparisons can be obtained.
 
The SIG P210 is generally considered to be one of the most accurate centerfire autopistols you can buy. It's chambered in 9mm.

The SIG P210 was designed and manufactured to equal the accuracy of the Swiss Luger. It does so in that gun's chambering of 7.65 Para. The 9mm Para guns fall a little short of the mark. Swiss bullseye championship shooters tend to prefer the bottleneck round.
 
My H&K P7 is considered by many to be one of the most accurate pistols available - At 7 yards, the groups I shoot are basically one big ragged hole - not even my Kimber 45 is that good

A ragged hole at 7 yards translates into 25cm groups at 50m. Most any 9mm service autopistol can do better than that. The HK P7 was delivered with groups under 5cm at 25m. The SIG P210 was delivered with groups under 5cm at 50m. The AMU Beretta M9 cuts that spread in less than half.
 
This 9mm is very accurate. I was at my Uncle's house this past weekend. He has a 2x2 steel plate set up at 90 yrds. I was hitting it about 20% of the time which suprised me. I didn't think there would be any chance of hitting it.

At regular handgun distances, thist thing makes ragged holes.

stainless Ruger P95, 9mm, 3.9" barrel; PC Ammo (remanufactured ammo) out of Lebanon, PA loads a hard cast 119gr cone tip leadhead that shoots @ 2" groups @ 15 yards offhand for me; it is just about as accurate as Hornady Critical Defense 115gr polymer tip jhp's that I tested in this firearm; I am satisfied with 4" or smaller groups at this distance since I go for combat accuracy with semiautomatics (in PA semiautomatic pistols are not permitted for hunting purposes) since I bought it for personal defense
 
It depends. Bullet style and weight. Propellant type and amount, handgun quality and type, and that's just a few variables.

The 9mm (.355) can be very accurate.

Do you attribute the accuracy difference to some aspect of the cartridge or to some difference in the way the two chamberings are implemented in the pistol?

I can only speculate that once and future practice of headspacing on the case shoulder is more consistent than provisionally fashionable trend of headspacing on the case mouth. Aside from that, there is no doubt that lower recoil inspires better accuracy.
 
I have heard no complaints from anyone as to any sort of inferior accuracy with a 9mm. I also have never heard it associated as a "firepower" round. Its shoots flat and as accurate as you can shoot given a quality gun, but it also isn't as powerful as a .357 Mag.
 
Accurate enough?

T/C G2, 10" bullbarrel, carbine stock and 12x rifle scope makes under MOA groups at 100 meter.
R-381 RN FMJ Lapua 125gr bullet, VihtaVuori 3N37-powder 6,2gr and CCI srp. (This load may be to strong for semiautomatic pistols).
