Swapping in known-good FSB and extractor assemblies from Glock 37 and then taking it to the range.
I've had the same intermittent & unpredictable experience with a couple Glocks in different calibers (a G23 and two G36s).
It always "felt" to me like the gun might be every-so-slightly out-of-battery; not enough to prevent primer ignition, but just enough to make primer hits slightly off center. So far I haven't figured out the reason, as the slides have seemed to be fully forward.
"Therefore, since the world has still... Much good, but much less good than ill,
And while the sun and moon endure, Luck's a chance, but trouble's sure,
I'd face it as a wise man would, And train for ill and not for good." -- A.E. Housman
Well, having switched the FSB and extractor assemblies between the two guns, the 39 is still having light strikes and the 37 is still running like a top.
The 39's problem has persisted through cleaning, degreasing, and replacing every single component except the frame, slide, barrel, slide lock, and slide lock spring.
I'm stumped.
