P938 is NOT any sort of a 1911, other than generally looking like a smaller version. I have worked on
1911s for 35 years, and have worked on one 938, and it isn't a 1911 inside. The design of the 938 is a
9mm stretch of the P238, which is a copy of the Colt Mustang. I believe that I read that the
Colt Mustang is a clone of the Astra .380 design of the 1920s or 1930s, I forget, which wasn't particularly
successful. I will try to find that source. I think it was Am Rifleman in the last year or two.
Didn't find the Am Rifleman article, but did find that the Colt was based on the Star Model
S, first produced in 1941, ended in 1965. This is the basis for the Colt Government 380, which begot
the Mustang and Pocketlite. When Colt dropped it, just as the CCW boom started
up (Colt, always headed in the wrong marketing direction), a few years later Sig picked it up
and did it better. Now Kimber makes a version, and Sig stretched it to the 938 in 9mm.
Colt went to a 1911 type internal extractor, the Star had and external like their Model B.
Sig has the same extractor, as does Kimber. I have a Star B, should look more closely
at it, compare to wife's Sig 238. I am guessing that the Star S/SS is mostly based off of the
Star B, but need to look at it. Pocket .380s were not popular in that time in the USA,
CCW was generally illegal.
The Star S/Colt Govt 380/Mustang/P238/P938/Kimber Micros generally look like and kinda-sorta based
on 1911 on the outside, but no kind of 1911 inside.
