Do 1911's slides run internally in the frame like a CZ?

CZ and their clones are the only ones who uses this design.

From what I can tell, it allows for a low bore axis, but makes it harder to grip the slide.

Yes, EAA/Tanfoglio, as well as the rest on this list towards the bottom. There might be even more clones of non 75 models.

The Sig P-210 inspired the Cz design.

Actually, the CZ design was stolen off the Browning Hi Power by the non-royalty-paying commies. (and don't forget that the HiPower design came from the 1911)

Other members of the Hi Power-CZ family include:

Baby Eagle
Jericho
Daewoo DP
Sphinx/AT
FEG/Mauser

I was answering in the context of question in the OP.

The Sig P-210 has the internal slide rails he is asking about.

The CZ-75 had inspiration in MANY preceding designs.

CWL,

I think you aren't recognizing that the CZ75 is actually a unique design separate from the Browning firearms you mentioned. For starters, the 1911 and High Power were originally single action designs. The CZ75 is double action. This obviously carries several differing design elements. The CZ isn't just an unlicensed copy of the HP or 1911. The latter being considerably different.
Also, the High Power owes a good bit of its design to Dieudonne Saive of FN Herstal after Browning's death.

So to answer the thread, No, the slide of the 1911 runs externally.

The only similarity between a hipower and a cz75 is the way they look externally. If you take the slides off and look internally the guns are totally different. Mark

The French M1935s too.

Didn’t the chain of inspiration go from U.S. m1911 to French m1935 to SIG P210?

Nope. Not directly anyways. True Petter's work was the basis for the SIG P210 and Petter had used Brownings tilting barrel design but he had incorporated a number of other features that wre unique. Swiss engineers used his designs as the basis of the guns that became the P210. The internal rails were one, the lock up another and the trigger system is different.

The period of time from the 30s to the 40s was a hothouse of pistol design and a good many ideas were swapped back and forth.

HK's P7 series of handguns also share this feature.

In response the OP, no they do not.

There are numerous sources to find the answer to the question yourself. A little research would have yielded that answer.

No.
