Does he have a gun on him?" Or "Do you have a gun on you?"

[tufguy]

Do we say "Does he have a gun on him?" Or "Do you have a gun on you?"

 

[Skrej]

Both are correct.

 

[GoesStation]

They're both possible but rather odd. You might ask if someone has a match or a half a dollar on them, but the expression is too casual for something as serious as a gun.

 

[Tdol]

How about Is he armed?

 

[Rover_KE]

To have a gun on you can mean somebody's pointing a gun at you.

 

[Phaedrus]

How about Is he armed?

Another option: Is he carrying a gun? / Are you carrying a gun?

 

[GoesStation]

Another option: Is he carrying a gun? / Are you carrying a gun?

American gun enthusiasts often shorten this to Is he carrying?

 

[Tdol]

Do you use packing in the same context?

 

[Tarheel]

Yep. (On second thought, it's probably more likely in the phrase "packing a pistol".)
