This Product Performance Advisory Bulletin is issued for the benefit of NAA's customers, owners and users of its .22 caliber revolvers. NAA has recently learned that the use of PMC .22 caliber ammunition (Magnum and LR) may affect the performance of its revolvers. Specifically, NAA has become aware of a phenomenon where an inadvertent, double-discharge (two rounds simultaneously discharging, one aligned with the barrel and the other out of battery) may occur when PMC Brand ammunition is used in NAA .22 caliber revolvers. These double discharge occurrences have been investigated by NAA and, based on the results of our investigation to date, it appears that the inadvertent, double-discharge has only occurred with PMC Brand .22 caliber ammunition, both in magnum and long rifle. However, NAA has not learned of any confirmed double-discharge occurrences involving any other brand of manufacturer's ammunition.

     At this time, NAA recommends that its customers, owners and users of NAA .22 revolvers DO NOT USE ANY PMC .22 CALIBER ammunition (Magnum and/or LR) in any model of NAA revolvers. As with all of its firearms, NAA encourages its customers to exercise the utmost caution and care when using its products, including always wearing appropriate eye and ear protection and following all of the Basic Rules of Firearms Safety.

     NAA takes tremendous pride in its finely crafted products. Its products have been certified by independent testing laboratories to meet or exceed every published firearms standard for safety, performance and reliability. All of NAA's products are warranted for a lifetime and its customer service and technical teams are ranked among the best in the industry, serving its more than 500,000 customers over the past thirty years.

     NAA appreciates that, among other things, its products are purchased and used as back-up weapons for law enforcement and for personal protection. As such, NAA recognizes that its customers should be supplied with any information that may affect the safety, performance and reliability of its products.
