    According to the article:

    The solution: switch to a small-primer pocket and utilize a small-rifle primer. Coelho reached out to Starline again, asking the company to make .45 Super brass with a small-primer pocket. That solved the primer-flow problem and Triton Cartridge soon began offering factory-loaded .450 SMC ammunition. It was loaded to a maximum average pressure (MAP) of 32,000 psi, which is slightly higher than .45 Super pressures, but still less than the 37,500 psi pressure of the 10 mm. The new name—.450 SMC—solved the trade-mark problem, and Triton had two loads: a 165-grain bullet at 1,450 fps and a 230-grain bullet at 1,150 fps.
    Starline apparently making them under contract for Triton, with the small primer pockets so we could use small rifle primers to stop the primer flow problem.
    The only source I could find was the Triton's web site and you would have to buy factory loads from them to get the cases.

    Thanks...I went there before asking. That site inso longer up and running and states it is for sale.

    Was wondering if anyone else happened to make the ammo or the brass...but guess I'll stick with 45 Super and keep waiting on Starline to bring it back in stock.

    Can't answer the OP's question with any knowledge of my own, but if the solution for most pistols is a stronger recoil spring and a better supported chamber those aren't major expenses to shoot a more powerful round and if I was so inclined that's what I'd do.

    However, I'm not inclined to do that and if I were someone doing research on higher power autoloading pistols (that are actually practical and not .44 AMP's) there is a factor to consider with .45 Super and that is this: it's not going to become as popular as 10mm is and it's not going to get the same support from ammo makers as 10mm does. My theory as to why is the concern the laywers have of .45 Supers going into old 1911's with weak recoil springs and improper chambers and BOOM; there isn't that same concern with 10mm.

    That's Phoenix M in full length configuration.

    I would love to find a threaded barrel for my 4506.

    They don't exist.

    For the 3rd gen S&W guns and many others for which no threaded barrels are available, we thread an OEM barrel in a fine pitch (usually 40 TPI) and manufacture a thin walled 17-4 H900 stainless female to male extension.

    For some, usually .22s and some .32s like the Beretta 81s below, the barrels are threaded internally and fitted with a male-male extension.

    When you say we, does that mean you do it ?

    My company has 3 employees including myself, so I refer to us as "we", but yes, I'm the one who does the barrel threading.

    Has anyone thought about the FNX-45? Allegedly its a fully supported barrel and I know that they take factory FNX barrels and ream them for .460 Rowland so they must be rated for 45 Super. The benefit there as well is you can buy a heavier recoil and magazine spring specifically for the FNX from the Rowland guys. I’m leaning that way myself for 45 Super if I don’t wimp out and just go the 10mm route. But if I do 10mm I have to buy new dies and all that.

    Very nice setup. Superior to the FNX45 Tactical in every way. Much better ergos as the slide release is large enough to push without having to break firing grip. The trigger feels much more crisp and tactile. And paddle mag release is superior to push buttons. Superior recoil system.

    The only pistol I know of that was designed for a constant diet of 45 super is the HK mk23. That is what was used to test that model during military trials, consuming tens of thousands of rounds. If I wanted to shoot 45 super, that's the gun I'd get.

    I have a write up about running 45 Super/SMC through my XD Tactical. I can post it if you care.

    Long story shot: XD ran with modification and without, just recoil felt different.

    I still have it, but I now carry a 10mm in Alaska for a more mainstream option

    I'm considering doing something similar, running 230-250gr bullets around 1000fps through a suppressor.

    I'm planning on doing it through a 1911 though.

    Any advice on setting it up? I know I'll need a new recoil and fitting pin spring. I've also got a flat base firing pin stop if you think it'd help.

    Make sure to use a model with a ramped barrel so you have a fully supported chamber, use a shock buff, and will probably need a heavier recoil spring to slow the slide more effectively.
