Two years past I watched a GM drop a loaded gun while holstering at make ready, last year I had to change britches due to an open gun going off when the shooter holstered it (a stone fragment whopped me in the leg and it took a moment to realize that it was only a harmless bit of stone) , and there is the USPSA fatality where a shooter sort of fumbled his gun without dropping it and it went off while he was trying to get ahold of it (as I understand it), etc.
All that to say that I think keeping the guns drop safe is very very important. If you can go sub 1 lb, shoot the gun throughout its lifetime and still have a drop safe gun, no worries then.
