Keeping firearms in the home is legal in Hawaii; but they must be properly registered.
The news as far as I know out here in HI is that the state's response is due on the 21st of this month (September), and the initial hearing for the preliminary injuction is on January 17, 2012. We're keeping our fingers crossed, and those of us who are military and therefore residents of other states are keeping a close eye on HB 822, the nationwide reciprocity bill.
Personally, I'm expecting a good laugh upon reading the thin gruel that the state will hang their case on, which I'm sure will transition into puzzled rage when the district court finds merit in their BS. We'll see!
Keep yer booger hook off the bang switch!
