@Claymore504: Thanks! I have actually come across some posts about the retaining pin when I was doing searches. I also found this video about replacing it:
https://www.youtube.com/watch?v=qkyAr5Z_kKUI may order a replacement pin just so I have it on hand. I am looking forward to shooting the gun a few times before I take that out. As far as I have been able to learn, it has only been live fired a few hundred times, probably less than 400. I doubt it has been dry fired much.
I have come across a lot of good information here and elsewhere. So far the recoil spring does not bother me, and if the trigger turns out to be similar to the other P-01 compact I tried a couple years back, I probably won't mess with the springs at least for a while. I may look into some of the fiber optic sights I have read about, but not right away.
