[T]he relative importance of home-made weapons in the Pacific has often been overstated. In reality, a length of water pipe firing mismatched and/or ancient ammunition can be as dangerous to the user as it is to the target, and craft manufacture is seen as a last resort.
Single-shot, smoothbore pistols and long guns are the only home-made firearms discovered to date, and these cannot be compared in terms of range, accuracy, and firepower to mass-produced, repeating firearms with rifled barrels and matched ammunition.
There is no evidence of local production of rifled barrels, nor of multi-shot firing mechanisms such as pump-action or lever-action, semi-automatic or automatic firearms in the south-western Pacific.
