Tell me about .38 Super

[MetroWest]

I swapped a 38 super ( Sig branded) barrel into a 40S&W chambered Sig 1911. Everything dropped right in and it runs fine.

Interesting - so a .40S&W cal 1911 seems to have a compatible breech face / extractor / etc. to work with .38 super barrel.
Google found CDNN is selling these for $39.99

The .40 is an intentionally emasculated 10mm auto.
The .357 SIG, and .45GAP are "answers" to a question that was not being asked.

"40 Short & Wimpy", as an old friend and 10mm fan called it.

Standard factory 38 Super is pretty close to +P 9mm Luger in performance. If loaded hot (38 super +P) it can approach 357 Sig performances. Really there was no need for the 357 Sig, and it's silly necked down case, since the 38 super +P was around for years (I say that sort of tongue in cheek as the 38 Super is too long to drop into frames that take 40S&W)

In any case, what makes it appealing to me is it's history. It was a magnum round before the 38/44 and 357 mag. Frank Hamer, the man who orchestrated the ambush of Bonnie and Clyde, used one.

It is said that the .38 super of old was popular because it would penetrate car doors, where the .45acp would not.

I have a Sig, 220, in .38 super. Using factory ammo, the velocity of the .38 super is about the same as the 9mm, Winchester, Ranger, 127 gr., +p+.

For all the shit SIG gets about quality, all my SIG 1911s can mix and match slides and barrels, at least in same caliber.

Breech faces are pretty close in size, but I wouldn’t count on consistent extraction / ejection.
