Should I assume that you mean the HK416 in .556X45??
That should do the trick. It has been field tested and is VERY much liked by those who know, i.e. SEALS & DELTA.

For a handgun there is **ZERO** wrong with the 1911 Government Model in .45acp.

No

Theres a new HK 45 auto out there, based loosely on the 1911, but with a polymer frame.

I DO think they ought to adopt the 416...but in 6.8 caliber.

Do a google search on the new HK 45, it’s really cool, and Im a dyed in the wool 1911 man.
