The Series 70 had a cross-bolt safety forward of the grip tang. In theory, the median joint of the right thumb would press it inward to “fire,” and it would have to be pressed back out from the other side for “safe.” In practice, most people found it not only different, but just plain difficult. The same had proven true earlier, when Beretta had put it on their 1951 model 9mm Parabellum service pistol.
