Yes, I mean literally weapons.
Do NOT use a real weapon for an audition. In fact, don’t use a toy weapon either.
A great choice is a tripod. Yes, a tripod makes an excellent shot gun. Please do not use your finger. Grab a substitution--a bottle, a flashlight, a rolled up side page. I have even seen a cell phone used successfully.
If you endow the prop and fully buy into whatever the device is, then we will likely do the same.
