While i only have ~100 rounds through my OPAP, i have a feeling it will start to mushroom. What are you supposed to do to the trigger, do you sand it down? I want to get a smooth sloped spiral, but right now its like a "triangle". Mind you, i cocked the rifle about 200 times and dry fired+had 100 rounds through it. No hiccups.

do you use a file or sandpaper, i never filed/grinded down a trigger before so uhh..this padawan needs to learn

I have a Tapco G2 in a kit built AK and after 500+ rounds it hasn't mushroomed.
Don't file it or grind it, you'll grind off the hardened metal and then it will mushroom or have other problems.

If you want a slick trigger, ALG Defense has put out an AK trigger with a shorter, lighter pull and reset.

Get a Power custom trigger and adjust the way you want. I think the entire hammer is hardened not just the surface.

Which is what you want, really. AK FCGs are and should be disposable wear items. The G2 FCG is, from the sound of the issues, way too hard.

Most imported FCGs are noticeably soft and will sacrifice themselves to form around the bolt/carrier profile - not the other way around.

Why do you have a "feeling" it's going to mushroom? If nothing's happening you should be fine, if it starts I'd just get another FCG as that's probably a sign the metal is too soft.

I think he's afraid of the bolt-tail mushrooming because of the over-hardened hammer and G2 profile, not of the hammer deforming. FCGs are easily replaceable; matching bolts, not so much.
