The H&K USP-45 is often described as a tank of a gun. I wonder if it could hold up to .45 Super?
I believe so though I cannot, at this moment, recall where I read it. The fullsize Springfield XD will handle it, the Glock 21 and select 1911s. As with many things, it depends on who you ask.
Has anybody asked the manufacturers? What do they say?
