The question is simple, in PB2.5 or the upcoming update of PB2; what or what kind of Trigger Action(s) do you want?
I'm putting mine here;
Assign sound 'B' as relaoding sound for weapon 'A', because Shotgun CS-DAZ has a reloading sound and if you want to make a custom shotgun using decors, you can't add a reloading sound to it.
