    This may have already been covered or just might be a stupid question, but does anyone manufacture a .357 Sig 1911? Could you shoot .357's out of a .40 S&W 1911 with a barrel swap like a Glock? I'd buy me a 3"-4" .357 1911 in a heartbeat. That is if it was within my price range.

    I have a friend of mine who had a 1911 made in .357 SIG by Night Hawk when they first opened their doors. To my understanding it was the only one they made. The guy works/worked at Great Northern Guns in Anchorage.

    I would almost bet that you could shoot .357 SIG out of a 1911 that was made for 40 S&W. They are the same sized breach face and the only thing that would be needed, IMO, would be a heavier recoil spring and barrel. A guy I work with had a barrel made for his Hi Power that was chambered in 40 to shoot .357 SIG.

    SIGShooter,
    I could see it working too, and working really well. You'd think that bottleneck cartridge would feed like a dream. I love the 1911 and really like the .357 SIG caliber. SIG should chamber their 1911 in it. I'd be all over that.

    Out of a 5" barrel with Speer GDHP…That round is smoking hot. If my memory serves me correctly, my friend was getting close to 1600 FPS. Now this is going back 5 years and change. So I think those numbers are right.

    I got to shoot the Hi Power. The recoil was a little more noticeable in that platform that in a P229. We did not chrono that gun though (Hi Power).


    EDITED TO ADD: I wonder if it is possible to have a barrel made for a P7M10 for .357 SIG. That would be cool!

    OK, what would the .357 Sig offer that the .38 Super couldn't? You're not going to get a smaller gun. The super with the +P loading should be about equal in velocity to the .357 Sig round.

    I don't believe the OP asked about 38 Super. He asked about .357 SIG.

    Just sayin.

    But, an answer to your question…I don't like 38 Super, I like .357 SIG. So as to what the 38 Super could offer, for me, would be nothing. I'm assuming the OP also likes the .357 SIG.

    :upeyes:I'm not going off topic here. I fully realize the OP didn't ask about the .38 super. I was trying to suggest that the reason you don't see the .357 Sig offered in a 1911 is that the .38 Super most likely already fills that void. The standard .38 super loading pretty much equals the .357 Sig. The +P load would likely go beyond it ballistically. Just like you don't see that many .40s. The platform is already adapted to the 10mm and the same gun in the .40 diesn't offer anything that isn't covered by the 10. I believe Para makes a .40 but it is a double stack and I don't see them hardly at all anymore. Now, if you could get a .357 barrel for an EMP, that might be worthwhile. I wonder if it would require a ramped barrel though.

    But that's not what you originally asked.

    In my opinion, the 38 Super wouldn't offer anything more than the .357 SIG would. I just happen to prefer the .357 SIG over the 38 Super. Now, in regards to the the 10MM…After reading the thread in caliber corner about bullet penetration…I think the 10MM definitely has more to it than a 40 S&W. And this is coming from a guy who doesn't own any 10MM but likes the 40S&W.

    No worries though.

    there are people that will make you a 357sig and/or set up a 40sw/10mm gun to shoot it.

    theyre not common because of the point SpS made earlier. 357sig was marketed to maximize the ballistics of the shorter round. 1911s work great with longer rounds.
    357sig is more common on the BHP platform.

    The reason that I asked about the .357 Sig round is because I like the round. I looked quickly at the Federal ammunition site and it looks to me like the 38 Super +P produces 1200 fps while the 357 Sig does 1350 at the muzzle. The SA EMP in 357 Sig would be the shizzle. Just my opinion.

    I'd love an EMP in 357. Would the bottleneck profile of the 357 make it feed more reliably?

    I cannot remember where I read it, but unlike other guns the bottleneck is not good for feeding in a 1911. Perhaps it was one of Patrick Sweeney's 1911 books? I am sorry I am not sure.

    I'm thinking it might need a ramped barrel to work reliably. Not really a deal killer, but the gunsmithing might put a dent in the budget if the base gun isn't already set up for it.

    My winter carry is a G32. I love the .357 Sig, in spite of the cost of the ammo limiting how much I shoot it. I have a 1911 in 10mm and a G20 and I get a charge out of shooting them.

    i like my G32* (nod to Joe)

    but in 1911 shooting snappier rounds than 45... ill take 10mm.

    the bottleneck does best in a ramped barrel.

    Just found out that Bar Sto already makes 357 Sig barrels for 1911. Apparently others are doing this already. Also found out that STI makes a 2011 double stack in 357.

    I've seen a couple .357 Sig 1911's. Makes sense to me. Ultimately, it can be loaded to slightly higher velocities than the .38 Super. There is also a larger variety of factory loaded defensive ammo for it. You can get more performance out of a 9x21 in a 1911, but there are some downsides also. Ultimately, if you want one, why not? That's the beauty of the 1911.

    The reason that STI is not making a 2011 in .357 is that some countries don't allow calibers above 9mm, and IPSC is allowing .357 Sig as an alternative for Major (since it doesn't offer capacity advantage over .40). There was a recent article in USPSA's Front Sight magazine regarding this.

    My question about a single stack 1911 would be about the magazines. We all know that typically the .40 and .357 Sig share the same magazines. However, in the P239, the most commonly available single stack magazine, they do use a different magazine between .40 and .357 Sig. :dunno: As it is, short rounds in a 1911 (9mm and .40) magazine is already a "tweak" by having a spacer to keep the rounds from "floating" too much in the mag (with a space in the front of rear).

    I've said it before, it's too bad the 9x23 round didn't take off. Ballistics out of a 5" 1911 was close to 1500 fps with factory ammunition using a 124g bullet.
