I have already upgraded my 4" XD45 (with thumb safety) with the Springer Precision "Reduced Power Trigger Spring" and the Spring Precision "XD Sear". Now I want to reduce my trigger weight pull by putting in different springs. (I dont CCW right now but I want to leave that option open) What springs have you bought to achive this? I would also like to shorten my trigger reset. I'm looking at getting either the Springer Precision XD trigger bar for $60 or getting the PRP "Easy fit over travel stop". If I go with PRP would I also have to get his "striker safety lever? Will either of those make for a shorter trigger reset? If those wont help me shorten my trigger reset what will? Lastly how much fitting would need to be dont on any of this?
