This solves over half of my gripes with the platform. If I could use premium JHP ammo with it, I would probably shut up and tell everyone else to do the same.
My problem with the slide-mounted safety is, when you rack it overhand, it is far too easy to move it to 'safe' inadvertently, which could cause life-ending complications if you ever had to clear a malfunction under fire. I had to train myself to rack from the front of the slide.
This happens with almost every new shooter I let have ago of a beretta as well, especially during and drills with speed involved.
