After an hour the pressure had dropped from 2000 psi to 1500 psi. Apparently this is a common problem. I will see if I can find the leak. Just shooting around the house and with a scuba tank, this would be a minor issue. If I wanted to go hunting all day on one fill it would not be good.
I dry fired it a few more times in the basement and the puppy upstairs didn't make a peep. The trigger feels OK with a bit of creep. I was expecting much worse. Many people said it may need more teflon tape at the fill fitting or the gauge. I like to tinker so I will do that.
