Just worked out a trade deal to trade my usp 9 for a 40. I can't help myself, need a 10mm H&K
Hopefully by my birthday i will be shooting some underwood 10mm out of my H&K(http://uploads.tapatalk-cdn.com/20160224/1830fa07d872ca2c2b8e349bf868ca53.jpg)
Is the grip area/magwell big enough for 10mm?

Yes,with different mags
These are really great guns. I wish they made them in 10mm. Have the usp tactical .45 and will never part ways with it.
If they fit in the magwell and action then it should be a simple ream job.
Here is a link to a thread on the HKPro forum. It seems the HK barrel is too hard to ream so you will need a EFK or other aftermarket barrel. I am also considering doing this also.

It's an excellent day on 10mm today! 8) ;D :D
So what will you do for the barrel? EFK shows none in stock currently. Hard to believe the barrel is too hard to ream.

My gunsmith says he can handle the hk barrel, tho im prob not going to use thr stock serialed barrel, but rather a hk 6" extended
Getting there on my 10mm USP build.
Tomorrow I should be picking up my USP 40, my 20 Lb recoil spring is ordered and i think i have decided on an HK made 6" barrel to make the most of the 10mm round. Only thing left is figuring out how i want to go about mags

That's the spirit!
So your smith can ream out the stock barrel? If so will you provide his contact info? Seriously considering this project if you get it running. Thanks, Nelson
Me too. Please either post up the info or PM us. And we want lots of brutally honest range reports. I have been devouring USP info, and have always loved the gun. The idea of having one in the one true caliber exhilarates me.
Riveted.

He says he shouldn't have a problem, though others say they are to hard to work on, once the barrel is done and seen thst it isb in working status im sure he will be happy to take on others

Trust me i will keep yous up to date step by step... im hoping if a decent number of us do this with the usp, maybe some company will hav thr balls to make a drop in 10mm barrel for usp 45, hk45, and hk45c once they see they would make the money.
Just got back from my gun shop with my H&K USP 40. Thankfully it won't be a 40SW long haha. Beautifully worn, but very clean. One step closer to the finished product and a true 10mm USP(http://uploads.tapatalk-cdn.com/20160301/c28d766922be0d60c68d0a4c9c474eb8.jpg)(http://uploads.tapatalk-cdn.com/20160301/786d0e68339b3a015138c1ada7dca1b3.jpg)(http://uploads.tapatalk-cdn.com/20160301/df391b8877979f2e3e533bd0b1f4c93b.jpg)
Do you have a picture of the mag with a 10mm round or 5 inside?

No, because they will not fit in the 40 mag, however the hk45/c mag holds them and fits magwell tight. My hk45c mags are just a tad short. Need to get hk45 mag to try and mod to fit nicely in frame

Here i have 12 rounds of 10mm underwood in a hk45c mag. The prob is the hk45c mags is just a tad to short to lock and load, the hk45 mag is longer and should lock in, maybe even able with a jetfunnel. Thinkin the hk45 mags hould hold 15 or 16 rounds of 10mm. And is i get the +3 mase pads can have 20 rounders if i want most likely time will tell

Great....thanks a lot! I was saving for a sharps.....now I gotta follow this ??? Oh baby, this sounds good! Keep us posted
I hope this project works out. Keep us updated.
Have some exciting news i will be sharing with yous by the end of the day
Ok so update on the HK USP.
Still yas a 40sw barrel. But i was able to borrow an HK45 mag from a friend.
It holds 16 rounds of 10mm!
That also means it hold 16 rounds of 40sw. And yes i tested it today. 2 mags with three malfunction 2 malfunctions were the last round open failed (an easy fix with a dremmer to make the slide catch not rub the mag) and the last round in the first mag flipped up and not into barrel. I think this is due to how short the 40 was compared to the mag and also limp wristing with one hand as i tried to video record myself while doing so. I think with proper length 10mm and stance will have no issues.
Now the hk45 mag does fit, but so snug it isnt drop free. (Not sure how drop free STI mags are) For me that is not an issue but other it might be. I also found eaa witness 10mm mags with the magwell so could easily be modifiedand cheaper than sti mags. Ive also found out that usp full size base plates fit the hk45 mags. This means jetfunnel base plates fit them as welll. This is good news as the hk45 mags stick out just a tad bit more than jet funnel mags. Meaning a jetfunnel kit is more than likely to work. The only thing im not sure of if i will be able to pull the mags out with the jetfunnel magwell.
But i think Taylor freelance +3 baseplate will allow me to pull them out and prob give me +4 or 5 in 10mm making it a 20 or 21+1 pistol with a slightly extended magwell. I will also be purchasing an elephant foot and trimming to fit without use of a jetfunnel kit for those who choose to go semi flush over a slightly extended option.
So far i think things are going smooth.
Hope my update was as exciting for yous as it was for myself.
Will post again soon. Feel free to ask any questions (http://uploads.tapatalk-cdn.com/20160307/0d91346d5b52ddc22baeae31b5039620.jpg)(http://uploads.tapatalk-cdn.com/20160307/dc6172261496598aa74c8b2c9ade8662.jpg)(http://uploads.tapatalk-cdn.com/20160307/df781b5773855cd0b01ed1c39bc8dd14.jpg)(http://uploads.tapatalk-cdn.com/20160307/eddec5250771a3763915e68a351a62a4.jpg)
Couldn't find a 40sw "sport" barrel. But ordererd a a threaded barrel and it has shipped and on its way to my gunsmiths..
Now i need to find who has thr best priced HK45 mags or 10round elephant foot HK45c mags and order a few
Thanks for the update. I have been wondering how it was going.
So my barrel is at my gun smiths, will be done the day the chamber reamer arrives (he ordered it, but the barrel shipped faster). I also got my 10 round HK45c elephant foot mags in..i modified one so far to work with the USP. Yes foot is a little sloppy. I did mean to make it a slight V shape to allow me to pull it out( the mags wont drop free but with the elephant foot pull out simular toa glock gen 1)(side note I think it has something to do with the USP mag release, and may try a hk45c mag release to see if makes any difference)
Yes i cut to far so it looks a little sloppy, but doesn't effect how it works. I also took a dremmel to where the mag rubbed the slide catch and took off just enough for it to move freely. Will post more soon!

Just got word that my gunsmith received the reamer today. He is working on thr barrel now and i will be picking it up in the morning!
Sweet!
This is getting exciting :o
Yes.... yes it is!
Well here it is guys (and gals)
My first 10mm Heckler and Koch
Just got done shooting it.
Put around 100 rounds of miscellaneous ammo through it
Rounds tried included
Remington umc 180gr fmj
Underwood 180gr fmj and HP
Sig 180 gr fmj & hp
Armscor USA fmj
Hornady 180gr XTP
PMC 170gr hp
The gun shot where i aimed it. Shot rather soft imo. I did have a few failures to feed but was only with the lower power ammo and i know its magazine related and need a little tweeking of feed lips. Im goin to try and post a short video shooting 3 rounds of the 180gr underwood gold dots
Next step is deciding what red dot i want to have it cut for when i have the ejection port opened up. My smith and i are going to attempt to finish the slide in a flecktarn pattern once the slide is cut and egravings are done..
But glad to say i now have a working HK USP 10mm.

Not sure if you have a local Smith already that you deal with but my gun smith and I were thinking about buying a few barrels and putting together a few hits once we perfect it.He's lookin into a few diff places to get the barrels and maybe get em cheaper in bulk. I can tell you I'm already planning on having another haha

As soon as i find out will let you know
jasonheimerm, thanks for the peak into your project and the video! Awesome! 8)
Yeah...I would probably go for one then wait to find the right deal on a USP.
Tagged, and in for a threaded barrel kit...
Well done sir. I'm glad it seems to be working out for you.
Hell, im in too
Small update. Messing around with a p16 mag i got. Will update more soon
I would also be interested in a barrel and then later pick up a USP
Made a few orders last night for the USP.
Will be doing the LEM/Match hybrid trigger. Ordered a jet funnel kit, LEM kit, match TRB spring, match sear, HK45c mag catch, a few different p16 mags, and a dawson mag extension. While the HK45 mag works(but is tight) the p16 mags seem to work nice other than the fact they stick out and look odd. So i figured id try an extension with the jet funnel kit .
If you would quit going to work and skip the family stuff this project could probably be completed :) :)
Keep up the good work, patiently waiting...
Have the LEM kit, match parts, jetfunnel and some mags coming today. Got to go to work but figured I'd strip the USP now and clean it and the parts up to save some time later. Pretty excited.(http://uploads.tapatalk-cdn.com/20160509/7b48b769ff56ee7ff815000f4fe9efb9.jpg)
Update. Place i ordered the new style hammer strut from sent wrong months ago. Finally got a new one and got around to installing it last night. Will have to take to range to fully test it. Should have an update much faster than this onehttp://cloud.tapatalk.com/s/582cac69a81af/20161116_124118.jpg? (http://cloud.tapatalk.com/s/582cac69a81af/20161116_124118.jpg?)

So I am midstream on my conversion (I posted under gunsmithing)
I bought a .40 EFK threaded barrel, bought a Manson reamer, and no-go gauge.
18# spring, jet funnel kit, and 2 STI mags...
I can't stand the thought of not having slide stay open after the last round....
So, I put the the .40 slide on my .45 frame; fits nicely except frame is 3 mm longer on the muzzle end...fired fine,except some rounds went over the chamber and locked the slide...
Now I just need to ream the barrel tonight or tomorrow
Then bend the .45 feed lips to fit 10mm;
Any updates lately?
Yes, any more updates? H&K is one of my favorites and your "adventure" into making a 10mm has been very interesting. Keep up the great work.
This thread makes my wallet hurt... ;D
