I don't know, I am not a gun owner, let alone an expert, but "old" guns (like the Colt .45/M1911) had AFAIK both a thumb and a grip safety[0], and (say) Beretta 92's had a thumb safety and in order to arm the hammer[1] the trigger needed "full travel", both seem to me like much safer than these "new" guns (against accidental firing). [0] and additionally you had to arm the hammer [1] unless manually armed
