Trigger reset after field strip

[aleph2024]

Hi everyone, I'm a noob ad I just bought a Canik TP9 SFX Mod2.

I tried today to field strip and noticed one thing, I've 2 basic questions:

 

1) The first time I just forgot to pull the trigger, and when the slide didn't fully move I just remembered, closed slide, and repeated.
Does this damage something?

 

2) Then, when mounting again, I tried pulling the slide but I pulled a bit too much and I reset the trigger in the same movement... Is it normal? Or this could be a problem?

 

Then I tried moving the slide back pressing the buttons at the same time, but it didn't fully clicked, so I try again moving the slide "with the inverted hand" , like the movement when removing slide, but reversing direction. This way it seems to just click but it's easier to not rack too much. Is this third one solution the right one?

Is it normal that if you move it exactly it does not "enable" the firing pin again, but if you rack it a bit more, it does?

 

 

Generally speaking, are there common errors in these things that may cause damages?

 

Sorry for my noob questions, I try to learn!
