Im not real hot on the grip safeties, on anything. Lived with them for years with my 1911's, and occasionally ran into issues with them either not working out of the box, or working when my grip wasnt perfect and I was expecting the gun to fire, when it wouldnt, until I readjusted my grip. Like most things, they arent "perfect", and we just add to the problem.
With guns I carried that had one, I always tried to make a conscious effort to make sure the grip safety was not depressed while holstering, which isnt always possible, especially under stress or distraction. The problem with the grip safeties is, with any kind of reasonable grip or pressure on them, they tend to disengage. In order to holster with them engaged, you need to make sure you change your grip to deal with that. Can you be certain you will do that "every" time?
Regardless how many safeties the gun might have, you still always have to treat them as if all of them were disengaged, while handling the gun, and pay attention to what youre doing, even when you cant. Better to get into the mindset that the gun doesnt have any safeties, and always holster reluctantly, no matter what it is you have in your hand.
All of this is really a user issue, and not a gun issue. Its up to us to know our guns, their manual of arms, and to deal appropriately. If youre too lazy to practice proper techniques until its down and done without "conscious" thought, or too cheap/lazy to regularly inspect and replace defective equipment as needed, then maybe you shouldnt be carrying a gun.
