The way CZ slides are inside the frames as opposed to the outside is this a major plus?or of no relevance? Do any other gun manufactures do this too?

Which was based upon the Pistolet Automatique Modèle 1935, developed by Charles Petter, engineer of the French company Société Alsacienne de Constructions Mécaniques (SACM).
Which probably had earlier antecedents....

I was told the same thing (as Wolfman said) yesterday when I went to look at a 75, although the guy wasn't sure which model Sig it was.
Besides lowering the bore axis it also adds bearing surface to the slide rails giving added support and more stability during the slide's travel.
The SIG 210 was noted for its stellar accuracy, but that's likely due as much to the precision of its workmanship as it is to the Petter-inspired design.

it's an advantage. more rail = more to work with and distributed load. CZ says it increases accuracy through rigidity.
Does the inside slide rail system explain why CZ's are so accurate? Makes sense, if the slide position is consistent, lock up is consistent, and the barrel returns precisely to battery eveytime, accuracy will benefit.
it's one of the factors that help contribute to it. good lock up is one of them. tighter chambers too -before i owned a gage, i test fit my rounds into my bare barrel. what didn't pass went in the practice bin. the rounds that go in the practice bin, some drop in and out of the XD barrel fine. at that point, it's not a fault of a pistol manufacturer, but a faul of the ammo maker. this was when i was buying factory reloads though, not factory new or handloads.
less frame flex and more mass up front is my guess. plus i can ride my thumbs higher on the CZs without fear of the slide rubbing, but dunno if that helps. might be a mental thing. but i do know my grip differs a little from when i shoot everything non-CZ.
Lower bore axis and more slide to frame contact more of the cycle adds up to more consistentcy. It does, however, require better cleaning to avoid wear.
It also yields the best accuracy I've seen out of the 9mm. Most 9s suffer from poor accuracy because of cutting corners in manufacturing of the gun. The cartridge itself isn't bad as far as accuracy. There aren't too many guns chambered for the 9 that are made to the same tolerances as CZs.

The more slide to frame rail equals more accuracy argument doesn't hold water in my book. One could argue that that would create a less accurate handgun.
My Glock 17L is currently the most accurate semi-auto handgun I own. I'm sure we're all aware of the amount of "frame rail" it has.
Barrel lock up, front and back, has everything to do with accuracy. In the case of the CZ I'm sure the lower bore axis contributes to accuracy as well.

my lowly firestar m40 slide rides inside the frame,and for a well worn piece ,ex range gun,and a firecracker to shoot in .40, its accurate for a shorter barrell.gonna p/u a 9mm..im a cheapy went from pa63 to sigma to star bm to a firestar,all been good guns.

If you read the previous posts you will realize this is false. (Not trying to be a smart*ss, BTW) The Sig P210 design is based on the French S.A.C.M. 1935A pistol. The internal rails and modular design are the major features that were copied. I have a 1935A and it is an accurate pistol.
