As many are aware, I, and many others, are disappointed with the trigger pull on the Glock 42. Based on information in some of the forums I tried something to reduce my Glock 42 trigger pull. Here is an example of the mentions of this as a means of reducing trigger weight, there are many similar posts and videos.
I replaced the trigger, and safety plunger springs. The basic theory behind it is that Glock uses the same springs on the Glock 42 as are on all other Glocks. Because the Glock 42 is smaller, it follows that there is more "felt" resistance when pulling the trigger.
After the change I noticed that I was occasionally having my reloads fail to fire. I would put this failure to fire rate at about 1%. The primers on these fail to fire rounds were clearly indented. Further, I could put that failed round into another pistol and it would fire on the first strike (well, the second, the first strike was the one that failed to ignite the cartridge. . . and yes, I know this isn't a safe practice; but I was curious).
I didn't have any issues with factory ammo, I am using Winchester Small Pistol primers.
Main point, if you replace the striker spring, test it a lot.
