Tasmanian Liberals have joined calls urging the State Government against relaxing gun laws following notice a new parliamentary inquiry into firearms regulation will be established.

Former Tasmanian Liberal Attorney-General Ron Cornish, who helped establish the National Firearms Agreement following the Port Arthur Massacre, says he is relieved the Government is halting reforms in lieu of an inquiry.

The proposed changes would have included increased access to silencers and category-C firearms and extending some licence periods.
