The issue with impairment under alcohol isn't whether or not you can shoot straight but is whether or not you can make a good decision to shoot or not shoot.

The standard for impairment while carrying a gun is lower than that for driving and can be proven by your conduct, by evidence as to how much you have drunk as well as through tests. However tests are not necessary.

Since I have never liked alcohol that much anyway and rarely drink, I don't drink and carry. If you do drink and carry, be careful because you are taking a risk of losing your CHL among other things.
