I have an s400 Xtra FAC on the way and the seller said the trigger was modified and has no return.id like to get a picture of the plate off from someone here as the pics I've found online don't seen to show where I think the spring would be.
It's also missing the trigger safety button.i guess my only option for these parts is across the pond?
Also it appears to have a full length barrel shroud.i can't find much info on this model.
Thanks in advance.
The older S400 did not have a trigger return spring and there is no provision to add one. I remove the return spring on the S500's I have because it serves no purpose except to keep the trigger from flopping around when the gun is not cocked and it adds a tiny bit of pull weight. The function of the trigger is not effected.
The safety button can be sourced from PA. https://www.pyramydair.com/s/a/Air_Arms_Safety_Button/4063. But you will also need the tiny detent ball, spring and screw if they are also missing. https://www.pyramydair.com/s/a/Air_Arms_Safety_Detent/4064, https://www.pyramydair.com/s/a/Air_Arms_Safety_Spring_Fits_S400_S410_S500_S510/4065, https://www.pyramydair.com/s/a/Air_Arms_Safety_Set_Screw/4066.
