A document included with all Model 3032 Tomcat pistols warns that the owner should never use ammunition that exceeds of muzzle energy. Notably, even normal factory .32 ACP cartridges have become significantly more powerful in recent decades, and can well exceed the 130 ft-lb limit of the pistol's initial design, one that Beretta continues to use to this day. Representatives of Beretta USA have often recommended that owners purchase their .32 ACP ammunition online, so that the muzzle energy is properly verified in specification charts. Use of any ammunition that exceeds this rating may cause irreparable or prohibitively expensive damage to the firearm, most commonly manifesting as a crack on the frame. However, contrary to common belief, this is not considered a defect in factory materials, but a problem caused by ammunition and the consumer's neglect of the factory parameters.
