Might sound like a dumb question...

You know how sometimes you press the trigger (only experienced this with ARs) but the round doesnt fire. When you eject the round, you see there's a dent on the primer. Is it bad to try and fire this round again?

No problems trying to fire it again, but it likely means that your hammer spring is installed backwards. There's another recent thread about this.

yeah, it sounds like you have the hammer spring in wrong...
