An interesting discussion would be are there significant enough differences in various brand striker pistols, to make some more or less acceptable for carry, or are all strikers "bad" for EDC.
The issue of this thread, however, is that Sig designed the 320 and marketed it as drop safe, and it isn't. The complaint with the 320 is not that someone got their finger on the too light bugger switch, but rather the 320 makes loud noises with no finger on the trigger.
