Changed out the TRS again after 15K. Wanted to cuss some more, so I detail stripped the P30V3. Very simple and straight forward IMO. I had the exploded diagram in front of me just in case I forgot what end was up. However, I did notice in the diagram Item #47 listed as Compression spring for recoil spring guide rod (234774). No, this is not the main recoil spring Both my wife's P30 and mine were purchased used and with 100% certainty did not contain this spring. Is this something they were both missing from the previous owner or did HK remove it at some point?
