Beretta 1301 Competition User Manual - Page 24

EN CAUTION: Periodically check that the choke tube is tightened correctly, ensuring that the shotgun is unloaded (empty cartridge chamber, empty receiver and empty magazine) and breech bolt in the open position. If necessary, firmly tighten the choke tube with the Beretta wrench. Correct tightening of the choke tube will avoid the occurrence of shotgun damage or injury. CAUTION: The choke must be kept correctly tightened in the barrel at all times, even during storage and cleaning. Cleaning the barrel without the choke tube installed may lead to dirt becoming lodged in the barrel thread and preventing the choke tube from screwing in properly, or to the formation of rust or obstruction in the barrel. WARNING: Never shoot the choke barrel without inserting a choke tube. Shooting without a choke tube in the barrel is very dangerous, as residues of lead or debris may become lodged in the thread creating an obstruction within the barrel. Also, not using a choke tube will damage the threading of the barrel irreparably and result in irregular shot spread. Do not alter or modify an existing fixed choke Beretta barrel for the use of interchangeable choke tubes. The barrel wall thickness would be too thin to safely contain the pressure levels generated by shooting. 24
