I'd argue that if you carry or store your handgun in a manner that would allow the trigger to come into contact with an object capable of pulling it through its full range of motion (or even touching it, for that matter), then you're doing things wrong from the start. So if you keep your finger off the trigger AND carry it properly, that pretty much takes care of the entire issue, not just 1/2 of it. There's no reason to be fearful of a handgun in a quality holster. Manual safeties require user manipulation, which means one likely failure is forgetting to engage the safety (the other is forgetting to disengage it). External safeties are not auto-magical, which means that the same training and practice that's required to engage & disengage them as required, could be applied instead to learning to use a striker-fired gun safely. I've personally witnessed NDs that were the direct result of people being sloppy with gun-handling because they had 'the safety on' (or rather, they thought they did). I was always taught as a kid to never trust the safety, and that teaching has served me well. I really see no functional difference between handguns with external safeties versus those that don't, because I treat them all the same. If anything, I believe the lack of a manual safety on at least some of the guns I've owned has caused me to become more vigilant regarding safe handling practices. Besides, Cyrus doesn't need no safety! Why should I?
