USPc Barrels

Does anyone make a .40 to 9mm conversion barrel for this pistol? If so, are they reliable?

When I looked into this a while back, general consensus was that you can drop a 9mm barrel into a .40 gun and it will mostly function, but the 9x19 and .40 slides have different breechface dimensions, so operation will be less than reliable.

The website doesn't show it as an option.

I'm looking for a true conversion that takes the breechface issue into account. Essentially a H&K equivalent to the Lone Wolf barrels that you can get for a Glock.
