Oleg,
Williams "Fire Sights" are tough enough.... but I don't remember if they make them for the Browning. They would be great for her to target shoot, but they need a good bit of light to make them work. Indoors, they really don't "glow" unless you are really close to a light source..... which we all know dosen't happen much in the HD role.
