    1911 in .357 Sig

    Hey guys,

    Just curious if there are any problems associated in doing a 1911 in .357 Sig?

    I'd like our smith do do a build with Caspian commander slide, with officers frame and thought I'd try a little something different. I already have about 5 1911s in
    .45.

    Thanks in advance for the input.

    I've heard it's very hard to get running. You should just get a 9x23.

    You're not the first to suggest the 9x23. Its a good round, but I just don't get aroused by it. It'll either be the sig round, or another .45 probably.

    Ultimately, it will be up to the smith. And I can't talk to him until I get out of this craphole.

    how is that?

    and I second that 9x23 in a 1911 platform. better round than .38Super too...

    Well, this will be a carry gun for the most part. The problem with the long 9's and the 38 Super is that hollowpoints are not readily available. And I'm not a fan of carrying reloads for self defense. I personally have no issues with it, but most juries, lawyers, and judges are, well, morons.

    Opt for the 9x23mm Winchester in a 1911. Anything shorter than 5" in a 1911, IMO, is not worth running.

    A .357 SIG 1911? The maths isn't really adding up. A fairly short cartridge in a relatively long receiver doesn't seem like a good idea. Magazines and spring rates...I don't want to even begin to fathom.

    Wasn't one of the .357 SIG design parameters to bring about .357 MAGNUM velocities in a four n' a bit inch service pistols? This just doesn't seem like a wise idea.

    I've seen this question asked of Ned Christiansen and he doesn't want to do .357s. For a reason. They don't like to run in 1911s.

    Winchester loads a Factory 125 grain silvertip that gives 1240 FPS... That is an outstanding handgun round... There is something in the combination of .357 + 125 grain HP + 1240 FPS = Shamwow on the human torso...

    I know it can be done because Bar-Sto makes barrels for it. I would talk to a knowledgeable 1911 guy like Jason Burton or John Jardine before starting a project like that.

    But the real question is why?

    A 38 Super loaded with Corbon DPX is a great defensive load.

    Springfield, Wilson and a few other manufactuerers have figured out how to make reliable 9mm 1911's and that opens to door to a very soft shooting platform to launch 127gr +P Gold-Dots.

    Terry Tussey is one name I've seen attributed to .357 Sig, 9x23 and 9x25 1911s...

    I have a Storm Lake 357 Sig barrel for my Colt Delta Elite , use the .40 S&W mags with the spacer in the back of the mag to compensate for OAL at it runs fine.

    357 Sig brass is the cheapest and easiest to get in my area and I handload so using the Sig round instead of 9x23 is cheaper shooting.

    I plan to load some up long and try in magazines without the spacer but I haven`t got around to it yet.

    Burton likes 9x23. Theres even a stack of it behind the counter in his shop. Next gun I get from him will be 9x23.

    Well, for starters, I'm weird about what I run. I have to be excited about a gun or caliber. For example, I bought a HK Mk23 last year. Why? I liked it and wanted it. I really didn't sit down and do comparison studies and what-not. Its the same with this project. The Sig round has been a success with agencies that use it, so its hardly an impractical round. And I like it.

    But the caliber was given a thumbs down by our smith who will be building it. He doesn't want to mess with the 357 in a 1911. So it will be the tried and true .45 which is fine by me.

    Another reason is that I work at a gunshop fulltime back home (I'm in Iraq now) I thought of the Sig round cause its more available and I can get it at a better price. I'm also set up with dies, etc for my Sig 239.

    I've *heard* that th 9x23 has a tendency to burn barrels out faster than it's slower cousins. (357sig and 38 super.) mind you, I've never owned one so I have no practical experience just hear say and conjecture.

    that being said I'm a hand loader and like to load my 357sig fast in my P226. But ultimately I shoot too much to push it fast enough that it causes premature wear on my barrel. it's my carry gun after all.

    I would love to mess around with a 1911 in 9x23 just to see if I can get a 125gr bullet up to 1900fps out of a hand gun. but it would never be my carry gun. but I'd love to get one and try to shoot out the barrel.

    You'd probably be better off with a 9x25mm Dillon.....10mm Auto necked down.....

    Actually I'm working on a Commander-length gun in .357 SIG right now. I've heard too that the caliber does not run well in a 1911 but I've sure-'nuff seen tons of 1911's in .45 that didn't run either. I'm not going to stick my neck out and say it will absolutely run, but on the other hand it seems like it maybe ought to, and Pat Sweeney reminded me yesterday he's had one for years, made from a Delta Elite, that runs.

    In the next month or so I ought to have first hand, personal knowledge. If it runs, I'll let y'all know. If not....... there may be nothing but static on this channel.....

    Great news! This one is my "Welcome home from Iraq" gun. I'd like it to be done before or shortly after I get home, so for this one I'm going .45 because I know for sure our smith can do a .45.

    I have a feeling this will not be my last, though. So if yours is up and running, the 357 is back on the list.

    Here are the specs I requested for the commander:

    - Stainless Caspian Commander slide. No rear sight cuts. No serrations.
    - Briley frame. Its forged instead of cast. I need a forged one for my serration plans.
    - Novak sights. 2 dot rear. Tritium from with white outline.
    - Ed Brown left side only safety.
    - Long, solid Nighthawk trigger.
    - Vickers hammer/sear/disconnector kit. The one with the slotted hammer, not the classical.
    - Ed Brown memory groove beavertail grip safety.
    - Ed Brown stainless hex grip screws.
    - Bobtail.
    - Recessed slide stop. Wilson, Nighthawk, Brown - any good one that is recessed.
    - Barrel - and quality commander barrel. Nighthawk, Wilson, Brown etc.
    - No light rail.
    - Good internals like Wilson, Wolff, etc.
    - Good one piece guide rod. Not sure if I want full length or not.

    Then I'll send it to Gemini Customs for a full Dragonskin treatment and a dehorning.

    I'm hoping Robar can do Roguard for the safety, beavertail, bushing, slide stop, mag release, and trigger. And NP3 everything else.

    I'm thinking Esmerelda grips for this one.

    What do you guys think?
