question about my ghetto blaster junk gun

I'm fixing to order a new firing pin for my super cool looking, but incredibly unreliable tec-9, and had a question first.

Last time I shot it, I had a round or two with a strike on the primer, but no ignition. I also had a whole bunch of times where I pulled the trigger without the gun firing, and no marks on the primer, but there were a few other times it still fired after that.

I've been thinking it's the firing pin, but I'm not sure, since it did fire after a bunch of misfires. The firing pin doesn't look deformed or anything, but it doesn't look as sharp as new replacement pins I've seen on websites, which has me thinking it might just be worn down too much or something, but it also seems like it wouldn't fire at all if that was the case.

Looking at the parts schematic on numrich, the only other thing that I see that seems to me like it could wear out and cause a problem is the sear spring. What does the sear/sear spring do? I'm thinking if the firing pin isn't the problem, then maybe the trigger doesn't have enough force to reliably ignite the primers now or something, but I really have no clue.

I had problems with it before where it would do the same thing (click when the trigger was pulled, but no mark on primer), and it ended up being that the bolt wasn't going all the way forward sometimes. The last time I shot it however, I made sure the bolt was all the way forward each time, and it was still having issues.

I've replaced the recoil/striker springs in this POS already too.

I'm going to order the firing pin regardless (they're just one of the many things that are known to break on these on a regular basis), but should I order the sear spring too? Or does that not have anything to do with the problems I'm having?

thanks

another question

I was just looking at the numrich schematic closer, and there's a trigger spring too. (Didn't notice it the first time). They're sold out of them, but I'd assume that would be the culprit, and not the sear spring?
