Is there a way to delay the initial firing of a gun for about 14.5 seconds?
(When you press the fire trigger "mounse fire" )
The reason for the delay is to allow the gun to "charge" which has the sound effect of a charging weapon. At 14.75 seconds, the gun fires at the apex of the sound effect.

This is what I've worked on but haven't tested it yet:
