1911 in .357 Sig?

gmarr · November 1, 2010, 06:36 PM

I know the 1911 comes in pretty much any caliber imaginable; I have a .45 and 10 mm as examples and have shot a 9mm and .40 caliber versions. But I also happen to like the .357 Sig caliber quite a bit. So naturally, the idea of a 1911 in .357 Sig comes to mind.

I have a Sig P226 originally chambered in .357, a quick barrel change and I have a .40 Sig. With the 1911 available in .40, how much work would it take to have one done up properly in .357 Sig? Does anyone make or offer one?

Thanks in advance

While there's no real reason you couldn't do it, I have a feeling you don't see it more because there are plenty of other fast 9mm/.38's available in 1911's such as .38 Super, 9x23 Winchester, and 9x25 Dillon.

The ballistics of the .357 Sig and the .38 Super (and .38 Super +P) are pretty close. The .357 Sig has a bottleneck cartridge, meaning the 1911 would probably have to be re-engineered to some degree. The .38 Super is a straightwall cartridge, like the .45 acp.

What is a .40 super? Never even heard of that!

If you want fast 9mm bullets from a 1911, don't go 357 SIG. That round is designed to shoot 125gr bullets from short-stroke autos. The 9x25 Dillon would be sort of a "357 SIG Magnum", and compatible with a .40/10 breechface. For a .38 Super/9 breechface, 9x23 gives you greater mag capacity and similar ballistics.

Never seen one. If I were to do a necked cartridge 1911, I think I'd want to do 400 corbon.

RickB nail it. That being said, the 357sig barrel in 1911 gives the option to load rounds longer and experiment with longer/heavier bullets ( if you are reloading )

Thats an issue I didnt take into account. Will the 357SIG case work with a .45acp breech/extractor? I'm guessing not, or at least, not reliably.

The 357 SIG uses a .40/10 breechface. If you want a necked-down round using the .45 breechface you can try .400 Corbon, but it sounds like a lot of trouble. .40 Super is, I think, a case based on the .45 case head dimensions, but stretched to 10mm case length, then necked to .40. A buddy of mine could not get a .40 Super Glock to work, even with help and free ammo from Triton (.40 Super supporters, back in the day). The Super still sounds like it may be a better idea than .400 Corbon, if the Super has a longer neck; buddies have had trouble with getting sufficient case neck tension in .400 Corbon.
