If I can clarify your question it might clear up the confusion. Normally a D spring is a term that is used to describe a hammer spring from a Cougar D model.
If I understand your question, you are asking about the sear spring from a PX4 type D. Since the type D does not have a sear it uses a similar spring in order to hold the hammer frame pin in place.
I have found it easiest to install that spring with the fire control unit removed and the hammer first removed from the hammer frame unit. Then, inserting the sear pin up to the point where it would catch onto the sear spring and then feeding it through the loop while the bottom bent leg grabs the frame the top leg will reach up and grab the crossbar of the frame. It might take a little push to get it in place, but that is its spot.
This second, blurry picture of the spring is turned to the left. But to match the picture above you would turn it over to face the right from our view.

It looks like LTT is offering frame texturing for Glocks. Has anyone heard if this might be coming for the PX4?

Is there any word on co-witness sights for the original RDO cut? I know pandemic delays got in the way last year, but I haven’t heard of any updates and I don’t do the ‘gram or whatever. Has the effort been cancelled in favor of the RDO 2.0 solution?

My friend, SteveB, just send me his brand new Compact slide with a 507 installed. I haven’t shot it, but I am quite impressed by the Langdon installation. It feels much more “integral” than the 92 red dot solution.
