Carbon... Hold on a minute. Did you read my post? I wasn't trying to speak badly of the 10mm. Heck, you are speaking to a guy who carries a 41 magnum. Dont' go there. I'm saying you are a bit off target expecting any great rush by manufacturers to make 10mm's.
For your information, FBI agents WERE graduating not being able to qualify with the 10mm. You cite anectodes and I'm sure many exceptions exist. Problem is, exceptions PROVE the rule. Look up sales figures. I'm not going to do that for you, but you aren't going to find any market to support the 10.
Let me cite other examples of excellent cartridges that SHOULD have a better market but don't have the sales potential. The 38 super comes to mind. How about the 38/45? The 9x23? The 356 TSW? The 9mm Winchester Magnum?
And don't lie by telling me that the 40auto only gives 334ft lbs to make some point. In fact, it averages about 400-450 with some loads in the 500fpe range. Picking the maximum 10mm loads and minimum 40 loads isn't going to prove your point. Heck, I'm with you. I'd buy the 10mm if I thought I needed it, which I don't. It's just a cartridge.
I tell you what, though. I'm already pumping out 45 Super ammo from a P-14 which holds 15 rounds of Higher power ammo shooting it more accurately than a Glock. To top it off, I can shoot 45 acp ammo with a spring change. Why wo I need to downgrade to the 10mm?
For the record:
38spl+p 125gr- 264fpe from a 4 inch barrel... Max load
357mag 125gr- 585fpe from a 4 inch barrel... Max load
10mm 155gr- 680fpe from a 5 inch barrel... Max load
40acp 165gr- 485fpe from a 4 inch barrel... Max load
45super 185gr- 694fpe from a 5 inch barrel... Only load listed

Looks like the facts prove exactly the opposite of what you were saying. The 357 magnum has over twice the energy as the 38spl. The 10mm has less than 40% more energy.
