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

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! ${$default_cool_smiley}$ ${$default_grin_smiley}$ ${$default_cheesy_smiley}$

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

Dangit, now you have me perusing USP 40's on Gunbroker.

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

sqlbullet · February 28 2016 08:58:59 PM MST

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.
