Gun Rights
John Cornyn (R)
Cornyn co-authored the Bipartisan Safer Communities Act (2022) with Sen. Chris Murphy — the first major federal gun-safety legislation in nearly 30 years — which expanded background checks for buyers under 21, closed the 'boyfriend loophole' for domestic abusers, funded state red-flag programs without mandating them, and authorized $13B in school mental-health funding. The NRA downgraded his rating from A+ to A in response, and Gun Owners of America has explicitly opposed Cornyn over BSCA — the same group endorsing Paxton in this primary. He previously authored the Fix NICS Act (2018) after the Sutherland Springs church shooting in his hometown region. He otherwise opposes assault-weapons bans, universal background checks beyond the 21-and-under expansion, and high-capacity-magazine restrictions, and has been a strong Second Amendment voice in floor speeches and committee work. The BSCA vote is the single sharpest substantive issue line in this primary — the moment Paxton's campaign cites most often.
Ken Paxton (R)
Paxton led the multistate ATF lawsuit that killed the Biden-era 'Engaged in the Business' rule expanding background checks on private firearm sales. He sued ATF over the pistol stabilizing-brace rule in partnership with Gun Owners of America, who endorsed his Senate campaign. He joined Montana-led amicus briefs challenging New York's Concealed Carry Improvement Act and ATF's bump-stock reclassification. He has repeatedly attacked Cornyn for negotiating the 2022 Bipartisan Safer Communities Act, calling it an infringement on Texans' Second Amendment rights. Trump's endorsement statement lists protecting the Second Amendment among Paxton's commitments.
