When your gun becomes more important than your life, there is a problem. If I tell you to drop it and you make any move with it, prepare to be shot. I've told you exactly what to do, you choose not to do so at your own peril.
Sorry Barney... I'm very likely going to lay it on the ground gently. The last thing I want to do is drop
a gun that may be cocked and unlocked around a bunch of nervous cops pointing guns in my direction. Dropping some guns can potentially discharge the weapon if it lands on a hard surface.
Futher, if you're so twitchy that you will shoot someone moving in a slow deliberate manner to comply with your order to disarm, you need some serious vacation time or a different occupation.
