M&P 22 pistol firing pin spring

[Tarkan]

Hi there,
well as you can direct from the topic title....after putting about 9000 rounds through my M&P (in about +2 years time), the spring (underneath the firing pin) gave up (broke).
I was wondering if anyone could help me with a partnumber since I can't find it anywhere.
The gun performed flawlessly so far (cleaned it each time after shooting and use CCI Standard/ HP and Minimags).
I'm quite attached to it so....
Greetings from Holland (the Netherlands)

call Walther! they produce this guns and they have other similar models, like the PPQ, that use the same parts! You can check the PPQ22 exploded view
