I had the opportunity to fire a fully auto version of this one in .45 ACP this past weekend. I found it had much less barrel rise than the last M-1921 Thompson I fired. Is there a civilian version available? In a semi mode how would it compare to something like the Storm carbine?

You can convert a USC carbine into a UMP.

HK USC plus UMP conversion will run you north of $4K when all is said and done, including SBRing it. And it will still be semi-auto only, no way to own a full-auto one as a civilian. But as a semi-auto SBR it is one of the coolest guns out there IMO. And it has NOTHING to do with call of duty. The UMP is just sexy.

I did mine for around $2K, everything new, although haven't SBRed it yet. One can save lots of money by shopping around for parts.

You are correct. It has EVERYTHING to do with Matrix Reloaded. :D

It's interesting to note that HK thought the UMP series would eclipse the MP5. As it turned out, the blowback action and lack of modularity only served as a reminder of how sweet the MP5 really is. I think it is interesting that the UMP is getting a lot of second wind in the civilian world. I think a converted USC is the best .45 carbine choice currently available, it's just that anything HK is going to require a really flexible billfold.

One of the reasons i think the UMP has failed to overtake the MP5 is that many are going to SBR ARs instead of either. However, the UMP, and MP5, really outshine the AR when used with a can for CQB, IMO.

Nope, a USC will never be a UMP, just a look-alike. I like my USC just fine as is it is. It would seem a shame to cut that barrel.

How do you feel about the aesthetics of the stock on the USC? I think "UMP" and go "cool-looking gun!" I see the USC and go "ugh"- that stock just looks ridiculous to me. I've never had a chance to fire the USC, but I feel like they ruined what could have been an awesome-looking weapon.

A USC will never be a UMP in the same way that an AR15 will never be an M16. Aside from the select fire capability a USC can be essentially identical to a UMP. Also, there is no need to cut the barrel as they are very easy to remove and install and short barrels are readily available. In addition to a 25 round capacity mag over the USC's 10 the UMP also has a far better grip than a USC and folding stock.

Don't blame HK. Without that silly stock there is no way the USC could legally be imported as pistol gripped rifles can not be imported.

I don't know too much about the legal ramifications of this, but can you do an after-import modification, through a licensed gunsmith? For example, import the USC and then slap on a different stock?

Yes, you can and i have. Like any other imported converted gun it must be 922r compliant. HKparts.net sells every thing needed but shopping around will allow one to find parts for cheaper than buying everything there. I'm not sure what you mean by "licensed" gun smith but there are companies out there like HDPS that will do the modification for you or you can do it yourself with a file and dremel. HDPS also offers packages including all work and parts but they are not cheap. You'd be much better off buying the parts you need and sending them in to have the work done. Detailed information is readily available on HKpro.com. Essentially you will need a UMP lower, stock block, stock and magazine. Available 922r compliance parts include stock, trigger parts, barrels and magazine parts. There are a couple of guys out there who will actually take a demilled UMP upper receiver and platic weld the back to a USC upper reciever so the stock block is not needed however this route is far more expensive.

Only thing I don't like about the USC, is the fixed stock. Other than that, and the front rails, looks exactly the same. I'd love a UMP/USC conversion myself :evil:
