I just bought a new SD9VE and disassembled the gun to clean it. When I removed the striker to verify that it was clean and dry I noticed that it has the heavy striker spring held in by the plastic keepers, but there was also a very lightweight, much weaker spring at the front of the striker pushing it towards the rear.

Well, somehow I got this lighter spring jammed up when I reinstalled and it bent. I took the striker in my SD40VE apart to see if I could 'borrow' that spring for a range test and found that it didn't have one. It just had the main striker spring.

Is that lighter spring even needed? I got my SD40 used and it must have not had it when I got it. I haven't had any problems with it in the approximately 700 rds I have put through the gun.
