Personally, it's not for me but I can see where it offers many features that will appeal to many.
I've seen a lot of negative comments about the grip safety, but to me I think it is a good idea for people who aren't the most experienced in handling firearms and especially for those that are worried about accidental discharges.
Having the grip safety gives an extra line of protection to prevent AD's for example if you're pocket carrying or a woman is carrying it in a purse. It might be possible to accidentally catch the trigger and fire the weapon accidentally, but now with the grip safety you have a back up safety that would help prevent that. It's also a safety that you don't have to consciously think about clicking off if you need your firearm in a hurry, because it automatically disengages the safety when you grip the gun.
Like I said, it's not for me but I can see it filling the needs of a lot of potential gun owners. I hope it does well.
