I contacted both Storm Lake and KKM. Neither will make a 10mm barrel. Anyone know any other barrel manufacturers?

Bar Sto. They're a gamey bunch. They might do it. Lone Wolf is a place to try also.

There are not many good 10mm rounds around anymore. Since the FBI had it loaded down it is not a really effective round. The best I could find for my Glock 10 was Buffalo Bore 1350 fps 40 cal.

I may contact them, but they don't make barrels for the M&P at this time. Therefore, it's a much larger undertaking for these two.

What is the real dimensional difference in the .45 and the .40 barrels? Realistically all they'd have to do is bore, rifle and chamber it for .40. That may be the gate way. People are so goofy about the 10mm. Oooh big bad casing. I think it's less pressure sensitive than the .40.
How far did you get with KKM? I'd think they'd do it if you could talk to someone besides the guy with all the "answers". Perhaps you'd get further with a short chamber .40 sort of how some manufacturers do with the .355 in 1911's. Would a Custom Fit barrel have enough meat to match up to the .45 slide? Are the lugs and hood of similar length? Perhaps you could get through the hoops to commission a .40 chambered barrel that required heavy fitting? It seems like somebody just needs to be talked to the right way.

You are welcome to try. The answer I received from Kevn at KKM was short: "Not at this time." The answer I got from Storm Lake was even shorter: "No" I guess it didn't even rate a period at the end of the one word paragraph.
The .45 slide is large enough. All that is necessary is to make a .40 sized chamber with .45 depth. Then bore the barrel to .40/10mm specs and you've got a 10mm barrel. I thought it would be easy for them since they already make .45 and .40 barrels. Apparently they don't see it my way.

That's completely bogus. You have to get to someone more customer service oriented. No or not at this time is not the proper answer. Quote me a price.
You missed the bus on what I was talking about. Dimensions of the barrels. I know the slide will work. The width of the hood and the length of the breech is what I'm interested in comparing between a .40 and a .45 M&P barrel. If they're close perhaps someone can be coerced into making a slightly larger .40 for "precise fitting." Try Jarvis also they made Jim Cirillo a bunch of different calibers for a glock 20 some years back 10, .40, 9x25, and .357 if I'm not mistaken. They might be able to adapt to the M&P. They're making P99 barrels so how hard can it be? Their website also suggests a more call and talk to us culture. It's pretty antiquated and the drop downs are simplistic. I'd contact them but I'm shipping out tomorrow for four months and may not see the answer.

No, I got it. The .40 is smaller than a .45, but if they can make a .45 all they'd need to do is mill the chamber and bore for 10mm. Further, since the bore is the same as the .40, the only area of difficulty is chamber length. I can't imagine it would be that difficult.
I agree that the answers were poor. I'm not sure I want to dance with them over this at this time.

Yeah I will try them in a few months or less if I have real time Internet available on the ship.
