Before deploying to Omar, Lorii had a chance to take her tiny sister Sophie down to the firing range and let her take a few supervised shots from her .22, but Sophie wanted to try taking a shot with Lorii's Big Girl Gun. Aludran 8.1x55mm is not exactly a round for a three year old and Lorii's rifle is actually bigger than Sophie, but they somehow managed.
(The Aludran attitude towards weapons comes from the fact that they're born with retractable claws)
