Update:
After filing down the overtravel stop to where it needs to be I took the gun to the range and had a number of misfires...
So, I contacted PRP and Daniel sent me a shipping label to send BOTH pistols for a free professional installation and adjustment of the kits.
However, during our conversation, he mentioned that the springs could be mixed and matched at will, so I put back the original striker spring while leaving the rest with the combat, reduced power springs.
And now I am a happy man!
Ended up not wasting his time and money by sending the pistols at PRP.

What an outstanding customer service!
I cannot reccomend PRP highly enough!

Thank you Daniel!
