The magazines with the blue follower do not have the load assist button. I called Smith & Wesson last week about this isssue and asked if they were going to release a true 10 round magazine with a load assist button? The customer service guy was clueless. He couldn't answer any of my questions. He also didn't seem to care about my complaints regarding this. My only hope is they rethink this and get on the ball and address it!
