9x23 J-frame
Has anyone converted a titanium .38Sp+/.357Mag J-frame cylinder to 9x23?

If anybody has, it will most likely be colt saa. I'm sure he'll pop up in a second or two. I know he has done so with larger frames - not sure with the J titaniums.
Adios,

No Bob,
I only converted 9MM J-frames. On my Model 940s I have just taken them to 38 SUPER
Once I learned about the PC 940 Specials that are Factory chambered in 356TSW, I did not worry about 9x23 Winchester in a J-frame
WC145 has a few Js that have been converted to 9x23 Winchester by Pinnacle, but I forget what models he used
JimCunn,
If doing one of these conversions, you want to start with a J-Magnum frame gun, not one of the older J-frames

I've converted three airweight 637-2 J-frames to titanium 9x19, but I'm leary of that with 9x23.

What would be gained by doing that?

9x23? Nothing.
Lots for 9x19.

Sorry for double post.
I can see some purpose for the 9x19 conversion, but the 9x23 puzzles me.

The reason for 9x23 is POWER. Then you can shoot 9x19 for cheap ammo and manageable recoil.
The only one I have seen was a 640 Magnum cut to take 9x19, 9x23
Win., and 9x23 SR.

I have seen your existing conversions.
I would not run 9x23 Winchester in a Aluminium alloy frame, it needs to be a Scandium alloy frame, or stainless.
If you have never fired 357 Magnum from one of the Scandium J-frames, try to do that before you commit to the conversion. Recoil with 9x23 Winchester will be similar to 357 Magnum
It is manageable, but not pleasant

The SAAMI maximum average pressure for 9X23 Winchester is 55,000 PSI. Measure the thinnest part of your J frame cylinder walls. Are you sure you want to subject that thin steel or titanium to that much pressure? Plus the recoil and muzzle blast from 9X23s in J frame snub must be horrendous. I have two 50 round boxes of 9X23 Win factory ammo for if I ever get one, but if and when I do, it will be a 5 inch 1911 with full chamber support ramped barrel that will weigh at least 31 ounces empty and have much thicker chamber walls than a J frame revolver. Here is a link to a Shooting Times article about the 9X23 Winchester: Pistol Powerhouse: The 9x23 Winchester

As Tim Taylor says . . . . . MORE POWER
It is no different than a person who carries a 38 Special wanting to go to a 357 Magnum
And of course, the 9x23 Winchester revolver can be reloaded Much Faster than it's 357 Magnum brother

In my case, it was more curiosity than anything else. One of my three 9mm titanium cylinders was inadvertently reamed for 9x23. I've never fired anything but 9x19 through that one, and doubt that I ever will - rapid unscheduled disassembles are not on my to do list.
"If you have never fired 357 Magnum from one of the Scandium J-frames,"
I haven't, but I have fired it from an aluminum framed 12oz J-frame (titanium cylinder and center pin). I much prefer 9x19 :-)

There are no Aluminium framed 357 Magnum Factory revolvers and such a conversion would not be safe

That's most likely true (I have the same concern), but the unmodified .357 titanium cylinders will also fire .38Sp and are quite safe with that. I prefer 9x19 though.

Help! ?
Please help and old man out here! ? What is the major difference between 9x23 Winchester and 38 Super? "SAAMI says" they are so close they could be twins! The 38 Super has a slight rim and the 9x23 is a true rimless case. The 9x23 has a .010 taper in its length and the 38 Super is straight! The chambers are cut different in regards to the free bore. I am presently playing with a custom 8 shot 38 Super revolver and am contemplating a custom cylinder for a 929. Every one I talk to say I should go to the 9x23, most of which shoot the bottom feeders! WHY?
I love the J frames but the 940 is no fun to shot for me! I can't imagine shooting a 38 Super in the J frame !

External dimensions are almost identical, but the base of the 9x23 is much stronger/thicker to withstand the higher pressures (55K v. 37.5K). Also, the rim of the 9x23 is rebated, while the .38s is semi rimmed. That said, many who have 1911 barrels chambered for the 38s or 9x23 have been shooting both rounds for years with no ill effect.

They are close but you can add the 38 Supercomp to the middle of the mix. Triplets 
The 38SC is rimless like the 9x23 but the 38SC (& 38 Super+P) has a straight case while the 9x23 has a tapered case like in the 9x19.
If the 38S+P/38SC chamber is cut on the generous side, & the 9x23 cartridge is sized on the minimum side, all three can run in the same barrel, as in my 1911.
