HK would make it if there is a demand for it.
HK in 10mm?
Apparently, some HK owners, who are also 10mm lovers, have "converted" full-size .40 Swishy-Walker HKs to 10mm, primarily by reaming out the .40 barrel to 10mm, and then slightly modifying Para Ord. P-16 mags in .40 S&W to fit the Hk's mag release (not sure if these were pre- or post-ban mags). They retained the factory recoil assembly (I would have sprung it heavier with Wolff's).
Reports were that everything worked fine - no jams, no blow-ups. The "converted" HK was said to be extremely accurate in 10mm, and the factory night sights still hit dead on the nuts to POA.
Do a Search for a poster, "Monte," from Alaska I believe.
Also, over on http://www.pistolsmith.com there was a long thread about this conversion.

This subject has come up a few times in the past.
Please take a number and get to the end of the line for people waiting for a factory 10mm USP. It starts behind me.

Add my 10mm vote too. I would have to ask for a compact too. I told the H&K rep at his visit to the local gun store a couple months ago this suggestion so I can say I at least tried. They discontinued my SS USP fullsizes and they are supposedly taking the 357 Sig Compact out too according to him.
I'm kinda surprised that someone like Jarvis hasn't offered a barrel if it's do-able. They offer the USP barrels in 9X21, .356TSW, .357SIG, and .400 Cor-Bon.
I remember reading Alaska Roy's posts about his converted 10mm, but it's been a while, and I couldn't find the original post by searching for "USP 10mm Conversion". There were a few posts that showed up with him chiming in about his, but there was an original post where he outlined the whole process.

H&K USP-10mm
Chime, snicker or chortle?
I guess that would be my que?
I'm currently questing a H&K P-7 M-10 to eyeball as a potential 10mm platform.
A smith on another forum claims he's done a couple so far, ya really gotta love the internet!
The USP-40/10mm conversion is relatively simple, one day at the store when the USP-40s were first introduced, well we were swapping mags around and discovered the Para-Ord mags would work! Well, since Monte was the experimenter and was gambling the price of a H&K, two days past and in came the roughly converted USP. I say roughly because we soon found that the plastic mag catch failed and was replaced with the USP-45 catch as it was steel.
The cheapo 10rd mag was updated to the Para-Ord hicaps with plus 2 base pads. That ladies and gentlemen makes for a 19rd fighting gun!

looks like demand to me Mr. Hill. There seems to be a fair amount of demand for any new 10mm auto pistol nowadays, atleast among serious shooters (us once-a-week + shooters are the ones that keep 'em in business anyway). WHy they arent punching out new 10's is a mystery to me. For crying out load, they just re-released the .405 winchester and the Winchester 1895 to go with it. I dont know about you, but I hear more people wishing for a new 10mm than a new .405.
Demand for 10mm.
People forget that during the supposedly "waning" days of the 10mm, Glock issued the 10mm G-29, along with the G-30 in .45 acp. When Smith came out with the 610 revolver in 10mm, last rites were being administered.
Then, as they were slowly lowering the 10mm's coffin into the cold ground of the Caliber Graveyard, Tanfaglio released not one but two 10mm Witness pistols in the U.S.
As they were throwing dirt on the coffin, Dick Metcalf and other gun writers, who had long since turned a blind eye and deaf ear to all things 10mm, announced a "sales spike" in 10mm handguns and ammo, primarily thru increased sales of the Glock 20 and S&W 610 revolver. Then come outfits like Proload and Georgia Arms offering hot, reasonably-priced, reloadable 10mm ammo.
As the 10mm's eulogy was being spoken, recent articles in the gun press confirmed the resurgence of the 10mm, notably SWAT's favorable review of the full-size 10mm Witness. Then came GunWorld's write-up of Texas Ammo Company's new "Express" line of hotter-than-average 10mm (e.g., a 200g Hornady XTP/JHP loaded @ 1250fps), released in time for the wake.
Further evidence of the 10mm's "death" can of course be seen in the impending release of Dan Wesson's 1911 Pointman Major in 10mm. Not to mention that Kimber is considering releasing its own 10mm, in light of all the Kimber .40 owners presently inudating Dane Burns with requests to "convert" their .40 barrels to 10mm, with a corresponding sales demand for factory DE or CMC 10mm mags.
Yep, no question about it, the 10mm's a "dead round."

Agtman,
That was great, one of the best posts I have read in a while.
Yep the 10mm is dead, that is why there is a backlog for 10mm magazines all of a sudden,,,,,

"I couldn't imagine the price of preban 10mm USP mags ***"
There never were "10mm USP mags," preban or otherwise.
Actually, according to the details of the "conversion," they were using ParaOrdinance.40 cal mags from the P-16. This would include the more expensive but still available hi-caps, as well as the cheap "postban" 10rders. See, e.g., the latest CDNN flyer.
On the subject of 1911 guns chambered for the "dead" 10mm round, the local gunshop in this area had 3 Delta Elites for sale prior to Friday. Two were standard blue ones in "excellent condition," with a couple of mags each, the other a decent looking stainless DE Gold Cup, with 3 mags, on consignment sale.
Both the blue DEs are now gone.
The GC had a price tag of $900 on it, but the shop owner says the GC owner will probably lower it into the $700 range after X-mas, as he is in immediate need of quick cash.
The shop owner expects it to go quickly, as he too sees a "resurgence of interest" in the 10mm. As many guns as this shop moves a month, he ought to know.

I'd like to see a USP Compact in 10mm. It doesn't seem like converting the .45 version would be too difficult. And I'd be happy with 10-round magazines - which is probably about what would fit in space available (ban or no ban) (I think the .45 version only holds 8 rounds in the mag).
I agree that there is still life in the 10mm. I know it's a different animal, but I can't figure why we need, for example, the 480 Ruger (or whatever it is). I think if Ruger would chamber one of their Polymer semi-autos for 10mm they'd sell a lot of them.
