primer indent when loading

Just like the title says, what causes this? Do I need to replace some parts? Can it become dangerous?

Very common occurrence when you're dealing with a firing pin that is free-floating. It's the inertia of the firing pin itself that's doing it. It can become dangerous if the firing pin becomes dirty with old, varnished oil, powder residue, etc., that will keep it from moving as it should, or keep it jammed forward. Happened to me once, with an SKS. Firing pin was gunked up, stuck forward, and slam-fired the 10-round mag in it's entirety when I released the bolt.

Thank you! Should I replace the firing pin?

Sir, with a free floating firing pin, like the Garand has, you will have a dent in every round with every single Garand in existence. It is completely normal. You should make sure that your firing pin is free floating but the free floating is why you have the dents. To make sure you are free floating with the pin, remove the bolt and shake it, the firing pin should rattle back and forth, this way you get the required dents.
