H&K with cast bullets

[rockquarry]

A few weeks ago I inquired here about shooting cast bullets in an H&K .45. I've since bought an H&K USP 45 Expert with an adjustable rear sight. Cast bullet loads have been at least slightly more accurate than two commercial jacketed ammos I tried. Overall, the pistol is very accurate, even more so than what I had anticipated. I've done all my shooting at twenty-five yards. I do get a slight lead wash in the bore, but that can be alleviated with a different alloy. However, I can't see that the wash hurts accuracy so far. My bullets are soft, but there is none of the heavy and detrimental leading some have described.

As for the gun itself, with traditional double-action, a de-cocker and a safety, you don't get much safer than that, but I never thought I'd own something with a polymer frame.

The problem I've heard about using lead in an HK refers to the PSP. Or the P7. The gun is gas operated, and as such is not very fond of lead bullets. Lead shavings, bullet lube.

Are any other HK pistols gas operated? If not, I don't see where there would be a problem.
