how to make NPC draw a random weapon?

[Zuzaski]

I want a NPC to draw a weapon from inventory at the end of a script

the trouble is, the player gives it to him, and it could be anything

I looked a the groovy mod what with its draw/holster weapon, but thats no help because I cant find what how grovysettingalert global value changes something grrr

 

I need this, otherwise there's a second or 2 until the npc pulls a gun and spins around, when its supposed to sneak up with guns a blazin

 

thanks in advance
