As far as Powder River anything, they are really high quality stuff. I don't have their over travel stop as I purchased their trigger which has the over travel stop integrated into it, but everyone else seems to really like the prp stuff.
My PRP Ultimate trigger kit for the XD9SC came with a trigger with a built-in over-travel stop. Fitting the stop to your preferences is just a matter of sanding it down until the trigger has the stop tolerance you like. Mine has about 1/64" of travel after the stroker drops.
I would use this kit if you do not want a full match kit. Also, you can use the stock springs if you do not want to lower the weight. This kit uses the trigger with the built in overtravel stop which you just need to sand down and the striker safety lever which reduces the pre-travel.
