Queensland's Deputy Premier Jackie Trad has accused the Liberal National Party opposition of sitting silent during a debate on tighter restrictions on the Adler lever-action shotgun.
The Labor government and the LNP on Wednesday night agreed to strengthen regulations that would limit access to the high-capacity firearm as part of a COAG decision last December.
But during parliament on Thursday, Ms Trad blasted opposition members for not contributing to the debate after one of its members broke ranks to vote against the reforms.
Member for Gympie Tony Perrett voted alongside One Nation MP Steve Dickson and independent Billy Gordon in support of the Katter's Australia Party's failed attempt to block the changes.
"What was also extraordinary ... is the fact that not one single LNP member apart from that member who voted contra to his party position, actually contributed to the debate," Ms Trad said.
"The leader of the opposition was silent in this debate.
"It was an unbelievable display of either indifference or complete laziness around a big national debate happening in our country."
Opposition frontbencher Tim Mander also spoke during Thursday night's debate before Mr Perrett, however he kept to the party line of opposing the disallowance motion, while also criticising the Labor party for being "skewed in favour of left-wing ideological policies."
KAP leader Robbie Katter accused the government of leveraging off the recent Las Vegas massacre when a gunman opened fire on concertgoers, killing 58 people and injuring 489.
He said the government should pay greater attention to restricting illegal firearm imports rather than licensed owners of a particular type of gun.
Mr Perrett said the government had stalled the measures in a bid to shore up votes from "inner-city zealots" at the next state election.
"The government is seeking to secure support from anti-gun activists at the expense of gun owners, because it is scrambling to shore up votes in anticipation of a state election," he told parliament on Wednesday night.
"These zealots want to close down any activity in regional and rural Queensland. We already have effective gun control laws in Queensland that protect people and ensure that only the most responsible people can access guns.
"The government should be focusing its attention on criminality and noncompliance."
Opposition Leader Tim Nicholls on Wednesday said his party supported laws introduced in 1996 by then prime minister John Howard after the Port Arthur massacre in which 35 people were killed and 23 injured.
