The 1911 is 45 ACP. They may call like pistols 1911. I call them 1911 like. I have 2 1911s and another that’s like a 1911 only it’s a 9mm something. J Moses designed the gun AND the cartridge in 45 ACP and that’s that.

And we get to the great schism that has divided 1911 worshippers to this day. I think of them as Orthodox 1911ers vs the Reform 1911ers.

Let’s leave for later the heretics who claim that the Browning High Power is the product improved 1911, for they will surely burn.

I'm a fan of the 1911 regardless of the cartridge. I'd rather have a 38 Super than a 9x19 though.

The Model 1911 was made only in .45.

There has been a commercial variant in .38 Super.

Colt's proposed 1911 placement that became the Commander was chambered in 9X19. The commercial Commander has been produced in 9x19, .38 Super, and .45 ACP.
 
Could the same also not be said of the Smith & Wesson Military & Police ? The original was a 6 shot .38 Spl build on the K-frame, with a pinned and tapered barrel and half moon front sight. Today's rendition of it ( cataloged as the Mdl 10- sleeved bull barrel, ramp front sight, MIM guts, frame mounted firing pin and an internal lock) is no less a S&W Mdl 10 than one built in 1918 is a pre-Mdl 10. Just because we don't like something doesn't change the nature of it. I can't in good reason look at a purple wall and call it yellow. So the same- the 1911 platform is just that. A platform.

1911's should all be .45.

I'm just not satisfied with the adjustments made to the pistol for 9mm use. It's not like it's rocket science to add a few lines of code to your CNC machine to make the pistol optimal for 9mm. I haven't seen many that were reliable. And many 2011 shooters are reloading very long rounds to help. The 1911 should have evolved more. But I guess all of the hacks from the past, Para for example, kinda ruined that for everyone.

That being said, I'm very excited about the Dan Wesson DWX's. A 2011 kinda thing designed from the ground up, specifically for 9 and 40, with a modern grip frame finally.

That is one answer to that question.

To circle back to the gun content using that definition: If a pistol isn’t manufactured to the specifications of the US Army pistol as issued then it isn’t really a 1911. No big sights, no lowered ejection port, no hand fitted anything.

I suspect everyone wouldn’t agree to that definition of a 1911.

I know I have said it before but I'll answer the original question again. A 1911 chambered in 9mm made by any of the reputable manufacturers will run just fine. It does seem that 9mm does run better with a ramped barrel vs non-ramped. As always use a good quality magazine. With modern ammunition, both 9mm and 45ACP will get the job done.

For all that say anything not in 45 is not a 1911. I look at the 1911 just like I do AR's. No matter what they are chambered in, they are still the same firearm.

Mr. Mosin,

If you want a 1911 in 9mm, I say go for it.

This is not intended to start a war, so... please... don't. This is a theoretical question asked out of curiosity; not a purchase/buy question.

Alrighty.... 1911 Gov't. Basic example of the platform, no custom nothing, hand fitting, etc, etc. Just a bulk production handgun. Hypothesizing acceptable reliability with either cartridge, steel bottomed flush fit mag. 7+1 for .45 Automatic, 9+1 for 9x19mm.

Would one be better off trading the +2 additional capacity of 9x19 for the lesser capacity (but possibly more effective) .45 Automatic ? FMJ or HP is irrelevant, the 9mm is still a small hole, .45 is still a big hole.

I know. .45 Automatic is what God and JMB intended the 1911 to be. Please attempt to remove the bias and put forth good points of thought.

It is REALITY/FACT, that with the BEST MODERN SD ammo there so little difference in the wound cavities produced by the 9, 40, and 45 that they are, for all real intentions, equal in 'stopping the fight'. So the caliber is not an issue. The REAL question one should ask is 'which platform', in these calibers, do I shoot best', as hit probability is the most important consideration is winning/surviving a lethal force attack. Just common sense. ;)

The thing about 9mm in a 1911 is the issue with a tapered cartridge in a single stack magazine. The tapered cartridge nosedives more than a straight walled cartridge. That's why some of the 9mm magazines are designed a little different, with a 'feed ramp' in the magazine.

A double stack magazine, if designed properly, can reduce/eliminate the nosedive.
 
Do a history search and you WILL find that JMB did not invent the 1911 in 45 Automatic initially. He was asked to provide a gun that met the governments criteria of a 45 caliber requirement. He converted his invention to handle the 45 Automatic round. The original round was of 38 caliber which is closer to the 9MM. Don't get me wrong, I'm a 1911 lover as well with them in 45 and 10MM variety. I have Glocks too.

The ''9mm is just as good.'' guys crack me up.

With modern self defense ammunition, dead is dead no matter what the caliber is. Shot placement matters.

Now when I was in the Army and we were restricted to ball ammunition (FMJ) then yes the 45 beat the 9mm for stopping power. But as civilians we are not restricted to using ball ammo only.

A 380 in the pocket is always better than the 45 left at home.
