1911C in .357 SIG?

Re .357 Sig Ammo: If you're a reloader isn't it as simple as using .40 brass?? Dies neck it down and away you go...
 
Pretty much but not quite. 357 sig spaces of the rim and 40 sized down are too short. You can however space off the shoulder and fit it to the gun which I plan to do.

Does anybody make one? for that matter would it be hard to do? Might be totally pointless but the idea has been running through my head the last couple of days.

Since 357 Sig is actually .355 (9mm nominal) dia, how about rechambering 9mm barrel? The only thing that I would definitely go is fully supported barrel, just in case.
 
Just adjust the load so your within the pressure specification for 40 S&W. You can also buy brass and there are cheap sources. But 40 is usually free.
 
Because it has cool factor and I want one do I need another reason? I was just saying it is possible and people will do what they want even if you don't approve. The SAAMI pressure for 40 S&W is 33,000 and 357 sig is 40,000. Easily in range for starting loads.

Well, you are certainly entitled to do whatever you want without my approval. My point is that loading a necked-down .40 to standard .40 specs at best gives you a 9mm +P. Just grind "9 mm" off your existing barrel and engrave it with ".357 Sig". That'll give you the "cool factor" for a lot less money and hassle.
 
True but when I get a 357 sig I'll can always buy some brass. I do know that 40 brass is free where as 9mm +P is not. I just want to add a bottle neck cartridge pistol to my collection someday. I also enjoy the sort of wildcatting. It's really all about enjoyment and satisfaction. I do see where your coming from though and I agree some of the advantage would be sacrificed.

No you're not supposed to use .40 brass for .357 because it comes out too short! if you want .357sig just use .357sig brass, or get a .38 super....

about the .45Super - I tried to finf out more about it a little while ago but couldn't find much, G37 where did you get your info on the caliber? Can you really use it in .45ACP barrel/gun? :confused: if that's the case how come .45super isn't more popular?

(notice that some of the kits don't come with barrels)

It's like the 10mm in the sense that you can load really hot with a nice, tight chamber and well made barrel; factory Glock barrel will buldge at lower pressures.

I am going to use my factory Glock barrel and just implement the heavier spring and buffer. Yes, the .45Super and .45ACP cartridges are indeed identical externally - A .45Super "modified" pistol can fire both :)

I think it's not popular because people worry about abusing their guns... if A G20 can handle 10mm; a G21 should be able to handle equivalent loadings in .45Super; my opinion :D
 
Thanks for the links...Before I checked back for replyes I googled the caliber (lol) and found that "realguns" link. Afer reading it I'm not sure Glock is a good idea for the conversion;

In worst case scenerio if the gun KB's I'd want my hand to be 'protected' by steel rather than plastic... (opinion after seeing few photos of GLocks after a KB with frames cracked open:eek:)

Light slides and alloy frames: Generally speaking, full size, steel auto's from most manufacturers can be setup for the .45 Super®. Ace Custom maintains a partial list. Beyond slide length, very low mass auto's like the Glock can't be converted, as well as guns with light alloy frames. The concern is that the slide will hammer the frame until it cracks. There are some exceptions of course. Some models of Glocks can be modified with a heavy bull barrel to make them functional with tactical level loads. I elected to go with an all steel gun that adheres closely to the 1911 design

All guns chambered for the .45 ACP cannot be converted to .45 Super®. Some limiting factors are: guns with alloy frames, guns with barrels offering less than minimal case support, an inability for a gun to withstand elevated chamber pressure, guns with low slide mass such as short slide Officer's models or stamped slide Glocks, guns that lack availability of heavy recoil and firing pin springs.

EDIT: I'm actually a bit intrigued by this caliber...but unless I can find some *real* load data for it. I wouldn't attampt it. IMO 10mm seams like a better/safer option...

In the case of most (if not all) steel and aluminum pistols, your hand is "protected" not by the metal frame but by wooden/plastic grips that have nothing but hollow space underneath. Conversely, some plastic guns such as HK USP are designed to crack along certain lines (see link below) in order to reduce the amount of injury to the shooter's hands. So I wouldn't assume that a metal gun is automatically better inc case of a kaboom.

In that photo you linked there's a chunk of the frame missing around the top/chamber area... 'Grip holes' on a metal frame are usually located well below the chamber area, so I still think you'd be better protected by a metal frame.

Btw to me it looks like that HK's frame cracked is a random spot (ckack line is different on both sides!),
 
"very low mass auto's like the Glock can't be converted"

I read that too... then I saw that the very company that stated that is selling .45Super Glocks as well as "kits" for them. Perhaps they are referring to the Non-Full Sized Glocks ;)

Currently Ace Custom .45's Inc. offers 10 different complete "45Super"® pistols, based on Springfield Armory, Para-ordnance, Kimber, and Glock Model 21 units and of course we continue to offer "45Super"® conversions on customer supplied weapons, as well as "Gunsmith fit" "45Super"® conversion kits, for Govt. Mod 1911 style pistols and 4506 series Smith & Wesson pistols, and the Glock M-21.

The barrel issue is noted as well and I am aware that I won't get to go as hot as the guys with their tighter chambers.

I am going to try 800X in the .45Super / 200gr XTP's; start light and work my way up one grain at a time until I see the warning signs pop their heads :)

I'll be doing a lot of single load, remove magazine then fire until I find my load.
Damn I can hardly wait - I'm just waiting on the brass.

By the way... I've ordered brass from "Double Tap Sports" in Manitoba(?) ,they are the official Starline Brass Importers for Canada.

:D

Reloading for the 357 sig is a pain, you can't just feed it 9mm bullets, the bullets for the sig have a longer bearing surface so you can seat them to the corect depth. I suppose in a 1911, one may be able to get away with 9mm bullets and the extra length.

But with the 38 super in the 1911 platform why bother.
 
I think with 357sig you need to use FP bullets instead of RN....

how much does the .45super brass go for?
 
.45 Super brass is $100USD for 500.
I am hoping I don't get dinged too hard for their import costs and profit (I'll post when I get the cost).

I am thinking about this freakin' cartridge daily :p driving me crazy... I got to try it :D
