One of the next handguns on my wish list is a RIA .22 TCM / 9mm combo (double stack M1911).  I don't really need a 9mm M1911, but since the extra barrel and spring comes with it, I'm inclined to rechamber it for 9x23 and then use cut down .223 brass for it.  So, I guess that would make it more akin to the 9mm Super Cooper wildcat.  It is my understanding that the .22 TCM was based on .223 brass, so the extractor should work without a problem.

I'm not sure I would do the conversion on the G20 though.  Do you still have the same magazine capacity or did it get bumped up by 1 or 2?

The .22TCM is based on the .223 Rem, but it's not only that simple. Whether using .223 brass for the .22TCM or 9x23, the neck has to be turned (quite a bit, you can't just "polish" it). Unless you ream the chamber for only that brass, they won't fit. If you do ream it, standard size won't fit.

The 9x23 Winchester is a very interesting cartridge. It's more powerful than the 357 Sig and the smaller case diameter allows for greater magazine capacity. I'm less surprised it didn't go mainstream than it not becoming more popular with handloaders and enthusiasts.

The extremely high pressures make muzzle blast and perceived recoil quite oppressive.

The 9x23 is everything the .357 Sig wanted to be, yet can't. It is the true .357 Magnum of the autoloading world. If I had one, I would want a 6" barreled 1911 version with a flat-bottomed firing pin retainer and an extra power hammer (main) spring. coupe this with a 23-24 lbs recoil spring and you'd have a marvelous combat/personal protection pistol.

Since the Wincheter 125-grain  factory loads mirror the 125-grain .357 Magnum loads from a 4" revolver barrel, a 6" barreled 1911-pattern autoloader would not only tame the cartridge's recoil, the longer sighting plane would enhance the round's accuracy. Talk about "opening up a can of whip-@$$", that setup would prove devastating.

Just my $0.02 worth.

Someone, Brad Miller, Ph.D., wrote an article about converting a Glock 20 to shoot 9x23 Winchester. It is dated February 18, 2016. I wonder if he got the idea from this thread that I started more than a year before he wrote/published this article.

This can be easily accomplished because Lone Wolf Dist. sells a 9x19 barrel for the Glock 20.  It can be reamed to a 9x23 chamber.  The 9x19 / 9mm Luger cartridges do fit the G-20 magazines.  While they fit and feed somewhat reliably, I'd never use this for a defensive carry setup.

I'm not really concerned about whether commercial ammo works since I'm a cheap bastard and I cast my own bullets and reload my own ammo. :)

I've managed to acquire a mid-size double stack RIA .22TCM/9mm combo and a full-size single stack one.  I'm still waiting on some parts to be available to finish the conversion of both of them.  The barrels that I decided to go with were the .38 SUPER barrels, but I will be making my brass from .223 brass.  I think that this means that my conversion is not a 9x23 or a .38 SUPER, but rather a .38 SuperComp.

Having read this thread several times and the linked article a couple of times, I have a question.  Wouldn't this conversion be possible on a G21 as long as I used a G20 mag in addition to the rest of the conversion parts?

I have the LWD 9mm barrel and a recoil rod and lighter spring for 9mm use in my G-20SF.  It not as reliable as I had hopped with the 9mm ammo.  They hung up on the feed ramp more than likely because they are sticking up higher in the mag as they are being shoved forward.  However I can still test the ammo from this 6" tube, someday I may have it cut for 357SIG. ???

The extractor does well to hold the case during extraction, not sure if the G-21 would without an extractor change to the 10mm extractor. ???

Thanks, this is going to take some thinking... :)

OK, I guess I need to run all the way down this rabbit hole before my mind will move along to something else.  Using a G21 or G30 (not 30S), would require swapping the .45 extractor for a 10mm each time you wanted to run the 9x23 barrel.  A better solution (in my mind) would be to spend the extra for a complete 10mm slide and set it up as the 9x23. Or 9x23 and 10mm and have 3 calibers from 2 slides.

Which brings another question to my mind.  Would a solid longslide or lightened longslide be prefereable?  Or just a regular 10mm slide?

And if the 10mm extractor is just OK at grabbing the case (but better than the .45 extractor), can a 9mm extractor be used in the 10mm slide?  I have absolutely ZERO clue on what extractor will work in which slide other than the parent caliber so if that's a square peg in a round hole suggestion, feel free to point and laugh... :D

Here are a few things to consider...It has to do with the fact that the slides of the G-20 10mm is wider than the 9mm platform slides.  And the G-21 is same width as the 10mm side although the reach is less because the larger diameter cartridge case.

There were issues using the 45 extractor for the 10mm cases, so they were changing to the 10mm extractor.  Also the breech face of the 45 is cut for the diameter of the 45ACP casing, this adds to the amount of slop side to side that can let the case slip out from the extractor.

The G-20 10mm breech face is cut wider than the 9mm although it can still hold and function.

So not only do you have the slop from the wider slide, but a 9mm extractor would effectively have an even shorter reach because of the wider breech face.  Or at least that's how my brain is perceiving this.  And I bet it's also why I haven't read of anyone using the 9mm extractor.

I like the idea of a hot, flat shooting 9 and I sure wish the .960 Rowland didn't sound like it's running at a super high pressure.  Isn't it basically duplicating the 9x23 but with the 9x19 COAL?  That's got to be some hellacious pressure.

The 10mm extractor provides more reach than the 45, The 9mm extractor may not work like you think!
The slop is because of the way the breech face is cut for each cartridge...using the smaller diameter case head than it's cut for adds to the slop.
