The H&K P7 was developed for the (then) West German Police. The accidents that happened with that pistol were then confined to police personnel. Bavaria, Lower Saxony mandated the use of the H&K P7 for all police officers. The pistol was also in use in Saxony as well as in Thuringia. In 1983 the New Jersey police were issued the P7. During the first month three officers shot themselves in the leg during training.
You claim that this is false data. My sources are the international weapons magazine " Visier", as well as various German daily newspapers reporting these incidents as they were happening. What is the basis for your claim?
