In addition to the youth protection act, gun laws were tightened. Although before the shooting comprehensive restrictions had already been decided and Steinhäuser only gained and remained in possession of his weapons due to the negligence of the responsible agency in enforcing them (he didn't register the pistol in time, forged documents for his shotgun, and despite the seller's inquiry, the agency granted the acquisition, see the Thuringian Report), further restrictions were added due to the events. The minimum age for shooters to acquire a large caliber weapon other than shotguns used in clay target shooting has been raised to 21 years and athletes under 25 years have been required to undergo a medical-psychological examination. Pump action firearms were banned altogether. Furthermore, the retention requirements for firearms and ammunition have been significantly tightened.
