I have only used Lissner ramped barrels for building single stack magazine pistols, so I cannot comment on the American variety.
The one I'm working on currently is a 9X23 that will be in a carry gun configuration, for a magazine article.
The available cases for 9X23 are, indeed, very stout. I have some of the primed Winchester cases that I have to cringe when I punch out the pistol primer, which I have to pay for and never use in a 9X23. The Starline Super Comp brass is a better way to go.
If you find a gunsmith who has worked on the Browning HiPower ramped barrel for a lifetime, you will find that reliability is more a function of the wrong bullet configuration than the ramped barrel. Out of a 10 shot magazine, in the Colt, you have 10 different bullet strikes (as you have 8 out of a .45 auto). You may run into some heartburn with some, but all can be made reliable with a little experimentation on the range, fooling with different recoil springs and using the proper shaped bullets and a good load of Universal Clays. Using the proper lubricating technique is also at the heart of the matter.
As I said, the Lissner barrels are superb, more easily mounted correctly than US made barrels and accuracy has been up to my greatest expectations. One downside: The barrel costs a gunsmith $300 before any installation work is done on it.
I would not dare to fire some of the 9X23 loads, sent me by readers, in my Colt; these are best reserved for a ramped and fully supported system. Happily, most shooters are not trying to make the 9X23 into something hotter.
When my dad bought his .38 super in 1929, he bought a couple of cases of the Peters Ctg. Co.loads. These cartridges were pulled off the market in '30 when shooters with the old 1900 pistols killed themselves with the hot ammo. American cartridge makers subsequently lowered the loadings for .38 super to proof for the .38 acp, and the super faded into the tree line. Now that those early guns are all in collections, it may be safe to up the super to its original ballistics for ones own use. However, when a hot loaded 9X23 gets slipped into an early Colt .38 or an Astra 400 (yes, it chanmbers and fires, but with catastrophic results) somebody is going to have a multi million dollar lawsuit on their hands.
Never fear, I'll cover your court case and write it up. And THAT is why some gun manufacturers and pistolsmiths will not make up 9X23 pistols or share their load data, and why some loading manuals ignore the cartridge entirely.
Since I really love this cartridge in the 1911, I'm going to propose a solution that will prevent this kind of mishap from coming to pass.
