Will the 1911 platform accept the 9X23mm?

Anyone know how well the 9X23mm performs as compared to the 45acp. & the Super 38?

Yes the 1911 will except 9x23
Thought so. Looks the 45acp & 9X23 case length is about the same.

Any idea on performance & availability? Seems like the 9X23 is close to the 357.

Back in the 90s Colt offered a 1911 in 9x23 and also a 38 Super conversion kit for that gun.

I have several 38 super/9x23 1911s.
Including this custom from @Integrity Arms.
The ballistics of the 9x23 125 gr bullet at 1450 fps matches that of a 125 grain .357 mag.
It is expensive but impressive to shoot.

An interesting read on the round...

https://en.wikipedia.org/wiki/9×23mm_Winchester

I have never gotten into it. I sort of went down the 38 Super Road and then turned off into the 10mm road. A comparison of the cartridges is interesting. Below the 9x19 on the left then a 38 Super (9x23SR). Next our good ol' 45ACP. On the right a 10mm (10x25).



Maybe someday I will want to hurt myself with reloading another round although I think 10mm Mag will come first although I could only shoot it in my Ruger Blackhawks right now.

By the way, I have a couple 1911’s & 2011’s in 38S and 9x23. All great guns barrels ranging from 3.24” to 5”. Powerful rounds and good for punching holes in things, great barrier penetrators.

@Dwe do you use the same barrel for .38S/9x23 or different?
Who are you asking? Personally, I would never use the same barrel for both regardless of those who say it's technically possible.
No I don’t fire them out of the same barrel.
The Valors original 9mm barrel was reamed
out to 9x23Win, and a new KKM barrel in 38super
was fit as it’s main caliber.

Both barrels were finished in DLC.

The builds I've done in this round are phenomenal. It's really a shame in my opinion that this round never took hold but, it was designed and introduced about the same time the double stacks were becoming popular and the 9x23 in a single stack just didn't get enough interest. I had the pleasure of talking to one of the Smiths involved in the design and bringing of the round to fruition. Chuck Warner was a great help when it come time for me to build my first one. And as ringing throughout this page a little pricey to shoot, but an absolute joy..

I'm a fan of the 9x23 Winchester, factory 125gr ammo gives an honest 1450+fps by my chrono, that's .357mag velocity for the same weight projectile. Very flat shooting and hard hitting, louder and more muzzle blast than 9mm or Super but recoil isn't an issue. The 9x23 brass is beefed up to handle the pressures so, as I understand it, if you handload you can push further than you might with .38 Super brass.

When I had my ORM 1991A1 Super built several years ago I had the 'smith fit 9mm and 9x23 barrels to it. Each barrel has it's own fitted bushing, to change calibers you just swap barrels, bushings, and recoil springs. I use 9mm mags for 9mm, Super and 9x23 use the same mags. Easy peasy. Shooting 9x23 is a hoot and it's a great self defense round.
