Starting this thread so there is one place to look for a way to replace the new Sliding lock with the old rotary lock. I found the old lock easier to work with the right thumb. I see why they changed it, the new way is far more intuitive for a new user. I stumbled upon the silent feature by accident. But I want the old way back! it's so much cooler and retro looking, plus a more natural motion. If any one finds a way to revert to the old lock, please tell!
