Some thoughts here...when Glocks first came into the country,they came in with relatively light triggers. Since the Glocks were the first popular striker-fired no-manually operated safety pistol, there were a spate of ADs as the guns were first integrated into law enforcement. I was one of the only gunwriters to flag the potential safety issues at that time (for which I took a substantial ration of 'Schumer'). Glock heavied up the production triggers shortly thereafter, and the rest is history.
I generally agree that some firearms lend themselves to the "expert carry" category for one reason or the other — the 1911 for a relatively complex manual of arms; a light-triggered Glock or any striker-fired pistol with a trigger-mounted safety and a light trigger pull, an H-K squeeze-cocker because of its non-intuitive cocking system. However, I strongly agree that any gun is dangerous if you don't understand how to manipulate it!
However, the 4 Rules solve all safety problems. I handle a lot of weird guns...some that cause me to say, what the heck? But the 4 Rules provide an absolute way for handling guns safely!
