I recently just purchased a Rob Allen 700 Tuna and after i load the bands i cannot engage the safety. Does anyone know a trick or some way to fix this problem? If i load the gun with the safety already engaged its hard to disengage the safety, but once i take the safety into 'FIRE' it wont re-engage. Anyone else have this problem? Its a really nice gun but i dont want to shoot myself or a buddy if a weed or something gets caught on the trigger! HELP!
