Beer Laws Missouri

Detail of the Missouri conceal carry law and alcohol please.?
I keep a loaded gun in my car console (which is legal here). I have a couple of beers with dinner and stopped and did not get a field sobriety test. What relationship (if any) between the loaded gun and alcohol in the eyes of the law? Do aggravated DUI? No relationship? "It also means a charge of gun?
If you have a carrying permit, no matter if you're drunk. If shooting someone in a drunken state would issue a bit more.
