Snap Caps, TRB, etc. ?s

[fizik]

So I've heard over time about using snap caps to dry fire. I just picked up a 6 pack ($25) while getting some slugs and other stuff. I'm wondering what use they really have in a centerfire gun (9mm) just for dry firing and learning trigger control and such? Isn't the firing pin going intoan empty chamber was no problem. I know rimfire's the exact opposite. I really bought them to load as duds for tap rack bang training, with someone else loading my mags. Anybody have some insight or experience or advice here? Just general info? Thanks in advance.

Oh, BTW, after using them a few times I notice a dent like I would see in a primer. so I assume theyre made of the same material or maybe something softer? Wouldn't that add wear to the firing pin itself versus it going into an empty barrel? Or is it the firing pin spring I'm saving wear on this way?

I'm confoozled!

It keeps the firing pin from peaning itself where it hits the slide/bolt when it goes forward, may also break there over time.
