The first 2 or 3 shots, when gas pressure is higher

Have you checked everything inside the loading muzzle to make sure everything is ok?

Apparently is all ok

Again, I would advise you to remove all your upgrades and re-install all the stock parts you took out.

then, test each upgrade part 1 by 1 to find the culprit.
FOr example, install steel the firing pin while keeping the rest of the parts in stock form. If that doesn't cause issues, remove it, put back the stock firing pin and then install another upgrade part.

The rubber nozzles of the magazines now ios the stock one, all the trigger/hammer mechanism is stock except for the knocker spring (upgraded to Guarder) and I tested everything with the stock recoil spring then now my pistol is almost stock except for the knocker spring.

I remember someone in this thread who raised the nozzle opening, where the rubber nozzle of the magazine makes contact, using epoxy glue perhaps to avoid my same issue

One by one.

You do this until you find the issue.

I'm truly sorry I can not help you very much. I can't see your gun, so I can't see how it behaves first hand. I'm only making assumptions.

I'm kind of curious though....
Have you tried swapping the Gas route packing from a KJW magazine into the TM magazine?
Not yet, I'll try soon
