The trigger's return spring is in the pierce pin assembly. The white delrin "nub" that protrudes from the rear of the assembly is what pushes the trigger back to reset after firing. You can modify this or come up with a creative solution of some sort, of course, but if you remove it you WILL need to do SOMETHING to reset the trigger.
