NASHVILLE — Happy-hour beers were going for $5 at Past Perfect, a cavernous bar just off this city’s strip of honky-tonks and tourist shops when Adam Ringenberg walked in with a loaded 9-millimeter pistol in the front pocket of his gray slacks.

Mr. Ringenberg, a technology consultant, is one of the state’s nearly 300,000 handgun permit holders who have recently seen their rights greatly expanded by a new law — one of the nation’s first — that allows them to carry loaded firearms into bars and restaurants that serve alcohol.

“If someone’s sticking a gun in my face, I’m not relying on their charity to keep me alive,” said Mr. Ringenberg, 30, who said he carries the gun for personal protection when he is not at work.

Gun rights advocates like Mr. Ringenberg may applaud the new law, but many customers, waiters and restaurateurs here are dismayed by the decision.

“That’s not cool in my book,” Art Andersen, 44, said as he nursed a Coors Light at Sam’s Sports Bar and Grill near Vanderbilt University. “It opens the door to trouble. It’s giving you the right to be Wyatt Earp.”

Tennessee is one of four states, along with Arizona, Georgia and Virginia, that recently enacted laws explicitly allowing loaded guns in bars. (Eighteen other states allow weapons in restaurants that serve alcohol.) The new measures in Tennessee and the three other states come after two landmark Supreme Court rulings that citizens have an individual right — not just in connection with a well-regulated militia — to keep a loaded handgun for home defense.

Experts say these laws represent the latest wave in the country’s gun debate, as the gun lobby seeks, state by state, to expand the realm of guns in everyday life.

The rulings, which overturned handgun bans in Washington and Chicago, have strengthened the stance of gun rights advocates nationwide. More than 250 lawsuits now challenge various gun laws, and Gov. Rick Perry of Texas, a Republican, called for guns to be made legal on campuses after a shooting last week at the University of Texas, Austin, arguing that armed bystanders might have stopped the gunman.
