I just realized something when looking at your gun again that I completely overlooked initially. That spurred hammer (also referred to as non-rebounding hammer) only appeared on pre-1994 P220s. The hammer rests directly on the firing pin, when improperly manually lowered by thumb while simultaneously squeezing the trigger. This carries the potential risk of the gun discharging when dropped directly on the spur, if the firing pin block somehow fails. Yeah, people being people do make this dumb and potentially fatal mistake. The transition to the new (current) hammer took place in 93/94. Don’t know why previous owner would have wanted to put this hammer in.

Anyway, your main spring-strut-seat assembly should be of the old style, if previous owner didn’t swap it out for the new style. So, you need the Wolff main spring for the early style. Can you show a photo, with a grip panel removed, of the strut/main spring assembly?

It’s the old style, but Wolff list a serial number lower than mine for these. Wasn’t sure if there was a 3rd style. One between the old BDA guns and the new plastic cap base guns.

Since your gun uses the spurred hammer (with its corresponding strut) that means pre-93/94, despite the gun being a ‘95 serial, I’ll venture a guess that you go with the main spring for the “P-220 West German/German MFG with serial numbers below G219166”. This serial number points to pre-93/94.

Not really related to the thread, but more to your point here.

About 10 years ago I ran into a guy that worked a gun counter. Probably in his 40's. He was ADAMANT that the Gen 2 Glock 23 in .40 S&W that he carried was made in 1986, when Glocks first started showing up. I said that I was 100% positive that a serial number look up, and the fact that .40 S&W wasn't commercially available until 1990 would prove him incorrect. An internet search would have easily refuted him. He would not budge, even claiming his Glock 23 was a "prototype." It was at that moment I realized ego was intersecting with psychosis.
