I guess it is no secret that I am partial to the 9x23.
Lets clear up a couple of things. Brass and ammo is easily available from ANY Winchester supplier. Some dealers just don't want to work very hard I guess. I buy brass from Black Hills Shooters Supply. Yes it is expensive and it only comes primed but NO OTHER BRASS (pistol) is even close to being as strong.
There is a reason Dick Heinie, Jim Grathwaite and I all have personal carry guns in 9x23.
I was asked to address Mr. Bowman's comments.
First his CUP figures are incorrect. Cup runs lower than PSI and these are the figures Winchester gives for there white box and Silver tip loads that run right at 1475fps from my 5" guns. 46K psi. Nowhere close to 50K CUP.(ie 55K psi) The brass maxs at 50K psi though, which is a medium rifle load in something like a 30/06. Winchester claims the 9x23 as THE strongest case made period. That is because it has a patented dbl blend web.
Typical figures for 9x23 are 46K psi or 41K CUP.
Rifle primers? No question if you are loading full house loads you want them. The primer is the weak link in this case. The factory ammo uses rifle primers for just that reason.
Primer shaving? Typically the guns and barrels are not made to the correct specs......hence pressure problems. A 9x23 is NOT a parts gun!!! Springfield and Colt made their runs from 38 Supers.......not the best way to do it but it was cheap.
The CZ/Whitness action is not strong enough to take a full house 9x23...it will have reliability problems and then break for several reasons.
A quality 1911 is no problem. 45 ACP runs at 20K psi, 9mm @33K psi, 38 Super factory @35K psi, 10mm and 40 @ 33K psi.
The differnce is the case of the 9x23 was built fromm the get go to handle the pressure. The 1911 is up to the abuse IF SET UP CORRECTLY. SPRINGS HAVE NOTHING TO DO WITH IT! I use a 16.5 and 18# spring to shoot major loads in a 5" carry gun.
BTW major loads in a Super are running in the mid 40K psi range also. The supported barrels are mandatory with a Super case to avoid disasterious case failure. Not so with a 9x23. The VAST majority of 9x23 guns I have built are all *unramped* barrels as did the Colt offereing in 9x23. That barrel design is more reliable and clearly safe with any load a 9x23 case can shoot.
I have fired 10s of 1000s of rounds of full house 9x23 in many different guns with no problems. You are not going to blow a case. A double charge will in fact blow a primer....not the case.
Its only failing in IPSC is that the brass is expensive and very few smiths know how to build to the high pressure and small rim.......nothing more.
Hope that helps. There are a number of issues not discussed in this thread that support the 9x23 in a 1911 format. It is worth takng the time to read the 9x23 info on my site and the article in GUNRAG if you have more interest. If you have more questions feel free to email me in private. Or notify me a quetsion is on this board.
John Rico (CP) and myself are doing 10mm Glock conversions to 9x23 but they aren't perfect yet. 9x23 will work on a 1911 better than any 357 Sig. Haven't seen ANY gun with the Sig round keep up yet on my chrono
Besides you get more ammo with the 9mm case than the 40 case.....seems like a step backwards to me.
All that said if I only had one 1911 I would have a 45ACP. Better be a very GOOD reloader if you want to play with this round and have a smith with his **** together. My rule of thumb is if the guy aint got a 9x23 himself and shoots it regularly.....find a smith who does, because I can guarantee your gun will not run long term.
