In my I had to put in 15# to reliably ignite factory ammo. Now i have 13# spring, but firing pin was ligtened up and welded up just a bit. No issues with win or fed primers, factory was ok too when i tested it.

Henning sells a long firing pin designed for the Stock II. It says for small frame, but in bold it specifically states for the Stock II. Frenchie has one listed on his store as well. That will allow you to go lighter on you main spring.

some are more reliable with other springs....my stock3 sets off more reliably with the same parts than my stock2 with the same hammer spring. Don't tweak that sear spring too much....as it may cause issues with the working relationship of the firing pin block and the firing pin.

try firing it in practice without the FPB.....if it does not malfunction, than the culprit is the relationship between the block and the pin, and not too light of a hammer spring or too heavy of a firing pin spring.

I found that the factory recoil springs were all over the place....I have had long 10lb,...short 10lb, 11lb,....and experimented with 8lbs. The 8lbs I found could shoot flat, but I found that depended on the ammo, also the slide does not close to my liking, ...slows down as the gun gets dirty. I prefer a short 10lb. I think wolf sells them.
