My taurus millennium g2 has a mount I'm looking at getting a light for it for night in case of an emergency. I've seen so many but they all seem to big or made for rifles. Any idea what I'm looking for? I'm looking for something affordable not to expensive. Something I can slap a rechargeable battery in if needed. I've seen them as low as 20 bucks and even 53 with lasers. I've also seen them in the hundreds and even thousands. Any idea and suggestions would be great. I'm new to this whole world this is my first gun.
