is it ok to use a super .38 single-stack magazine filled with 9mm ammo to a 1911 9mm pistol?

Answer 1

2py is right, if you reload your own ammo just increase the OAL of the cartridge. This will cause the pressure to drop alittle but is will still be safe. Otherwise the width of the shell is .394 at the base of a 9mm and .406 on a super. The shell may ride higher in the mag than normal, just function test it and if all seems well, try it.

My brother has a early model para ordnance 40 cal that suffered from bullet dip in the mag, and we solved the issue by seating the bullet a hundredth longer.

The gun Will Not blow up, changing a mag has nothing to do with the guns operating pressures.
Apparently not many people read your question carefully, you are using a 9mm cartridge in a 9mm chambered gun....

Answer 2

You can do that if you don't mind getting a new nickname like "Lefty" or "Stumpy". Your gun is made to use .38 Super. That is all you should be shooting in it. Period. And it is plenty strong. I have a RIA 1911 that I converted to .400 Corbon, and have several thousand rounds through it with no problems. It is as good as many of the lower end US guns. Better than most. It is no Kimber, but the Philipinos know how to make a good 1911. Seriously. They appreciate them just as much as we do here in the US. Your gun will handle any factory ammo you want to run through it. Even the P+ loads they sell at Walmart. Don't try the suped-up +P+ loads that some of the race gun crowd loads, as your gun is a stock 1911, and does not have a supported chamber designed to handle those loads. I wouldn't run them through my Colt 1911 in .38 Super either, for exactly the same reason. As for pressure differences between .38 Super and 9x19, they are minimal. And well below the max allowable pressures in a 1911. As for the other rounds, neither one is long enough to headspace correctly in your gun. They may very well chamber, and they both use the same .355-356" bullets. But they won't be held in the gun right. So at best, your extractor is the only thing holding them against the bolt face, and it will break if you fire the gun like that. At worst, you blow your gun apart, and damage the slide, the magazine, the chamber, your hand, etc... It really isn't worth it. The only semi-auto gun that was designed to swap .38s and 9mms was the Astra 400. It could use either .38 ACP (the much lighter forerunner of .38 Super) or the 9mm Largo, which was the same length, and only had very, very minor differences. It was not designed to use 9x19, although some people did do that, with varying levels of success and injury. Unfortunately, many people over the past 90 years have heard rumors about guns being able to do that, and have blown up a variety of guns monkeying around when they only had a part of the whole story. Don't add your name to that list. (edit) Thinkingblade, the .38 Super has been around since the 1920s, and didn't start out as a wildcat. It was identical to the older .38 ACP, one of the original Browning cartridges, except that they added more powder to it in order to up it's velocity. Hence the "Super" name. "Magnum" meant a large bottle of champaigne at that point in time. The shooting game crowd rediscovered it when somebody figured out you could load it hot enough to make Major, and get an extra round or two in the magazine over a .45 or .40. The semi-wildcat version of the round is usually loaded much hotter, but is dimensionally almost identical in most cases. That one needs a fully supported chamber, or you blow the bottom of the case out when you fire it. Oh, and I like your knives.

Answer 3

I would highly recommend that you just go to a gunshow or find a suitable 9mm mag for your model 1911 pistol. They are probably under $20.

I don't see a big problem with using a 38 super magazine, so long as it FITS into the mag well of your pistol. I think the main difference will be in the length of the magazine follower. (38 Super is a bit longer cartridge case than the shorter 9mm Parabellum.)

Answer 4

I cant speak for a 1911 style pistol but a Sig 9MM mag will handle .38 supers just fine. If you order a 38super mag from Sig you'll get a 9MM. Just make sure the cartridges are set solid in the mag.

Answer 5

Why take any chances? Use the correct ammo and magazine and stop playing games.

Yes, you may get it to work but it will never be reliable and likely will create some type of damage to you or the gun. If the factory didn't care what you shot in it or what type of magazine, the caliber would be listed as " Whatever".

You could also probably use diesel fuel in you regular fuel car and get by with it for a bit. Then you would have some problems. Play it by Hoyle and you'll be ok

Answer 6

I have a 1942 Italian Beretta. It is a 7.22 mm. I can use .32 shorts in it but it will jam every now and then. It is still accurate enough to use for varmint hunting. I do this because the 7.22 ammo is hard to get. Go to a gun shop and compare the diameter of the bullets and check the difference of the charges. It might work but I would test it first mounted on a gun stand and stand back. Fire several rounds through it , like a 100 or so.

Answer 7

its ok if it works 100%. your main problem i think would be the bullets would dip forward causing feeding problems especially if you do not have a ramped barrel on your 1911.
difference in lenght of 2mm+ between 38s and 9mm.

Answer 8

Well, it's not gonna hurt anything. It might not fit, or it might not latch and it might feed poorly, but it certainly isn't dangerous. Even if you mixed up and fed it .38 Super ammo it wouldn't chamber anyway so no danger. Try it if you want, but my bet is that it will be disappointing.

Answer 9

It probably won't be reliable as the .38 Super is a longer cartridge than the .9mm.

Answer 10

Why certainly... have at it... just make sure the hospital knows how to reattach fingers and hands.

NO... mixing ammo and magazines like that is STUPID and can get you killed or seriously hurt.
