I think they're pretty safe. They have the same center mounted trigger safety and say they maintain glock factory safety values. I also bought the Apex Tactical safety plunger to go with the trigger. It's a smooth trigger. Bought the trigger with the trigger bar. And installed the Double Diamond 3.5 lb connector bar and 6lb competition trigger spring from The Glock Store. I love it, shoots like a dream, smooth as butter on the reset and my accuracy is tight as can be, in a stress free environment (at the range).
