Only two things...
1. The trigger pull looks a tiny bit shorter than it should be.
2. It would be neat to have the option to hold the trigger down after firing to see what happens if you "work the reset".
Then again, I'm a nitpicker extraordinaire!
Very nice work. Especially good on the trigger/striker spring compression. The only other animation I've seen shows the striker spring compress simultanously as the trigger resets--you've got it right, the striker spring offers more resistance than the trigger spring so the trigger resets before the striker spring compresses much.
Any rules or requests about posting links to your animation?
