One of my 80% milled into a 100% had a problem with the firing pin punching through the snap cap and getting stuck in the firing pin bore. I did not figure this out until I could not get the slide to move back out of battery without a lot of wiggling and trying to move it, then it broke free. I noticed that the firing pin where it gets hit by the hammer did not come back through the firing pin stop. After a few Whisky Tango Foxtrot moments, I looked up and saw I had a couple Wolff Extra Strong Firing pin springs I found when I was doing some clean up and swapped out the firing pin spring. Works great now with no more fireing pin sticking.

Frame is a Urban Survival Arms 9mm Government for a ramped barrel.
Slide is a Rock Island 9mm slide.
Barrel is a Rock Island 9mm 5" barrel.
Grip Safety is a Rock Island Beaver Tail.
Firing pin is an 80 series instead of a 70 series
Hammer is a low mass hammer.
I listed the parts used in this 1911 for reference.

It could also be the firing pin bore is not sized correctly, burred, or not centered with the firing pin hole.

I have a Springfield 9MM Range Officier that I was getting some light strikes, so I replaced the factory firing pin with a steel Brown pin. Dropped in in and the first dry fire the pin was stuck about 3/8" past the breech face, it was far enough forward that the firing pin stop would fall out. I took a lot of time with sandpaper to reduce the diameter of the pin for it to work. I would hold the paper in my fingers and spin the pin with the other hand, rinse and repeat until it fit.

I had to ream the firing pin channel as there were burrs. Basically the opposite issue as the OP, but it was disconcerting. After 250 rounds though, no issues.
