Hawaii lawmakers hope to prevent a mass shooting in the islands, by banning bump stocks.
One of several measures this legislative session aiming to tighten gun regulations.
The nation's worst mass shooting in Las Vegas last fall sparked legislation at the Hawaii State Capitol.
"Bump stocks are precisely what the shooter used to increase gun fire to enable him to kill more victims. So I introduced a bill to make it clear that they are illegal," said Representative Gregg Takayama.
Bump stocks can be attached to a semiautomatic weapon and when a trigger is pulled, the kickback will cause the weapon to fire continuously without lifting the trigger finger.
"There is no practical reason from a recreational or sporting viewpoint for something that fires at the rate of an automatic weapon," added Takayama.
Bumps stocks used to be available at Honolulu Firearms and Range.
"We've taken them off the shelf since the Vegas shooting and don't actively sell them anymore. And if the bill goes through we will destroy them," said general Manager Rocky Davis.
On Wednesday, the Koko Head Shooting range quickly filled up with those taking aim at targets.
Some gun owners said they've made modifications to their rifles to make them more responsive and accurate, that includes adjusting the trigger.
"If i adjust it to where I'm thinking, 'Here's my target, squeeze, and boom it goes off when i want it to,' then it makes the rifle more accurate," said gun owner Cal Kealoha.
But some worry the measures go beyond banning bump stocks and would outlaw any trigger modification.
"The current bills that are going through the Senate and the House are so vague that they target very minor modifications, like match grade triggers, even lighter triggers for people with physical disabilities. The language is so vague you would be lumping a large population into instant criminals," said Devin Sasai, the owner of Bushido Arms & Ammunition LLC.
The Hawaii Rifle Association stated, if the trigger modification language is taken out of the bump stock ban, it would NO longer oppose the measure, which passed its Wednesday committee hearing.
There are other bills this legislative session that could also impact gun owners, including one that would only give gun owners 24 hours to sell or turn in weapons -- if they had to voluntarily give them up, because of a TRO or other court order.
