A judge is allowing Massachusetts Attorney General Maura Healey to continue her investigation into the gun manufacturer Glock.

Suffolk County Superior Court Judge Edward Leibensperger wrote that Healey has "good and sufficient grounds" to request documents from Glock "based on safety and other concerns about Glock pistols owned throughout the commonwealth."

Healey, a Democrat, has often butted heads with the gun industry, most notably in an effort this summer to reinterpret Massachusetts' assault weapons ban to include additional types of guns.

The Republican/MassLive.com reported in September that Healey had launched an investigation into the safety of guns made by at least two major national gun manufacturers, Remington Arms Company and Glock.

According to court filings by the companies challenging Healey's request for information, Healey requested numerous documents related to gun safety. She asked for records of complaints relating to the safety of firearms and ammunition and to accidental discharges, and for information on how the companies responded to those complaints.

She asked for information about recalls of guns and ammunition, a list of all guns being produced, information about safety features and testing and documents about advertising, marketing and warranties.

Healey wrote in court filings that her office has authority to investigate the safety of all consumer products, including guns, that are available in Massachusetts. She wrote that Glock may have liability in Massachusetts for things like product defects, misleading marketing and failure to honor warranties.

Glock had asked a judge to overturn Healey's request for documents, arguing that it was overly broad and burdensome and asked for information that was irrelevant to Massachusetts because it involved out-of-state sales.

In an Oct. 28 ruling, Leibensperger found that Healey was within her rights to request information.

Glock does not sell pistols directly to Massachusetts consumers because the guns do not conform with Massachusetts' safety requirements. But the company does sell to law enforcement and to wholesalers. State data relating to gun sales and private transfers found that there were 10,800 Glock handguns sold in Massachusetts between Jan. 1, 2014 and Aug. 13, 2015.

The judge found that because Glock handguns are being sold in Massachusetts, Healey has a right to investigate whether the company is conforming with the state's consumer protection laws and whether it has been selling guns improperly.

The judge did not rule on a motion by Glock to limit what documents Healey could request, instead providing guidelines and ordering Glock and Healey to negotiate the scope of documents and file a status report with the court.

"We are pleased with the court's decision, which allows our office to go forward with our inquiry into safety concerns about firearms manufactured by Glock," Healey said in a statement. "The gun industry is effectively exempt from federal consumer product safety oversight, resulting in an unparalleled lack of transparency and accountability around this potentially dangerous consumer product. Our office is seeking information that will allow us to determine if these guns are safe and we will evaluate it on the same standard that we would apply to other manufacturers under state law."
