Last year his bill didn't get to the floor.
His latest bill requires background checks on all private gun sales and transfers.
He says he's trying to close some of the loopholes.
"The reality is we know Oregonians support closing these loopholes so felons won't have access to guns. The latest data over the last two years shows there are 190 gun sale denials a month, where individuals failed the background checks on those transfers."
The background check legislation has to pass out of committee on Thursday to have a chance of passage.
Senator Prozanski says he's had assurances that if the committee approves the bill, it will at least get an up or down Senate floor vote.
