Is this normal?

There's an initial "click", somewhat heavy and loud, to start pulling the trigger. It does it the exact same when assembled. After that, the pull is very smooth.

The yellow arrow is the safety where the tension is coming from. If I pull the trigger by pushing up on the white arrow, the click doesn't happen.

I'm typically a Sigma or Glock carrier, and neither do this. Is that how the safety is supposed to work, or is it worn somehow and not moving out of the way like it should?
