I must have misunderstood. My bad. 
hrm… if I can find some decent reloading data for that you could be on to something.
is there a 10mm M&P coming out? 
Is Jardine even in the gun building biz anymore? Last I heard he stopped taking orders for Valtro pistols.
Hope no one minds me bumping this back up.
I was hoping Mr. Christiansen could comment on how the .357 Sig build is coming along.
I know that Jeff Hogan at Warrior Steel in Albuquerque was working up this platform. I don’t know what the results were from that. Lemme ping him and find out.
This project is coming very slowly but in about 100 rounds sofar, no feeding issues, with Gold Dots and SXT’s.
that’s encouraging. any specifics Ned - barrel length, velocity, mag capacity???
It’s a single stack, mag cap is 8. Barrel is about 4 1/2", with a compensator. This is the first comped 1911 I’ve done in a long time. It works well with a high-strung round like .357 SIG of course but it is LOUD. I have not graphed any of these rounds and might not be able to get around to it.
Thanks for the update! I’m glad to hear that its working so far. I’ll have to keep this in the back of my mind for the next 1911 project.
I’d love a 1911 in 357 Sig.
It’s done and running. I’ll post something about it int he “1911 picture thread”.

My good buddy, and fantastic gunsmith, Bob Delmore, built a Caspian based .357 Sig Commander sized pistol, a couple of years ago. It was my pleasure to do the test firing for him, to ensure reliability, and to regulate the front sight height. It did require just a little more TLC to achieve perfect feeding, compared to a .45 build, but it was nothing major, and gave me an excuse to shoot the thing a bit more. I don’t know if I’d go for one myself, versus a .38 Super or a 10mm, but it was a sweet shootin’ little bastard. It was LOUD and real damn accurate.
I would be all over a 10mm 1911 if I had the money.
Contact Chris James at Combat Precision in Atlanta at info@combatprecision.com. Chris made a 5" gun for a mutual friend/aquaintance of ours who was training with an agency using .357SIG. According to Chris it ran like a scalded dog. Here is the link to his 1911forum post. He could provide you with some good insight. It was one of his early builds, but Chris knows his stuff from operational use of 1911.

Here is a pic of the gun.
.357SIG in a 1911 is one of those why? things.
In a 1911 I’d rather have the better performing and cheaper to reload 10mm.
.357SIG does what it does well in a 9mm/.40 sized gun.
Totally agreed!
A good friend of mine is having one built, or it might be done by now, but the answer to why for him was. He is a TX DPS officer. He has an buttload of FREE 357 SIG. So free was his reasoning.
That would be a damn good reason. I know an IPSC shooter who built an Open division gun in .357SIG for this same reason.
He is building it off of a Colt, and he shoots alot of 1911s, so he also has the regular gear, holsters and stuff. It was a no brainer for him. My only concern for him, was going to be where to get good magazines. I think he might have that fixed by now. But if you have thousands of free rounds laying around and when he is off duty he has a 1911 on his hip, why not have one with free duty loads.
Since posting this thread quite awhile ago, i have come to the same
conclusion. I still think it would be fun to build one, but a 10mm makes more sense to me. Ned, that is one he’ll of a gun you built!
