Brooke Mueller carrying gun in L.A.

Brooke Mueller carrying gun in L.A. She's probably the last person who should be handling a firearm -- but yesterday in L.A., a cowgirl-hat-wearing Brooke Mueller dropped by a local gun range ... and waved around a real-life handgun.

It's unclear if she actually shot the thing -- we hope not -- but her rep Steve Honig tells TMZ, "Brooke enjoys sport shooting, and has for some time. She knows how to handle herself at a range and is a very careful and skilled sport shooter."

No kidding ... just look at the focus in those eyes.
