Wolff spring challenge. Bought a service pack for the 1910, serial number 10063. The striker spring was most important to me, but it doesn't fit. It is longer than the original, but I could make that work. The problem is that is a bigger diameter and doesn't fit into the striker cylinder... You know how the back of the striker is hollow to allow the spring to slide in about a half inch. That half inch, plus the extra length, doesn't allow the slide to move back enough to lock open. I did the stretch that Burgess recommended on my original... Have a call into Wolff... I will report the outcome.
The whole reason I wanted the springs was because I experienced some light strikes, but while I'm at it... The recoil spring they sent is also substantially longer than the original. I got it in and working, but now I'm thinking it might be too strong, and... Wrong.
Just a heads up for those who might be going this route!
