Walther blank-firing replica guns are now available in the United States through distributor Maxsell Corp. These automatics incorporate 9mmPA ammunition that is larger and 20 percent louder than the former 8mm ammo. Importation of these realistic replicas has been approved by ATF as complying with all U.S. safety laws. No federal license is required. According to testing results, the replicas are as loud as a genuine firearm and the pitch and tone of the report is very similar to a gunshot. Because they also load and fire in the standard form, these replicas are ideal for training. It is advised that hearing protection and shooting glasses be worn when using these replica firearms.
