sight for colt python

i need help finding a sight for a colt python.
i am not familiar with guns, and i want to get this as a gift for a freind.

any advice will be great!
thanks,
Jonathan

Sorry, can't help. The only lasers you can use with a Python will be a trigger guard universal mount system that are useless junk and that anyone with a Python would be ashamed to install, or something on a top mount from someone like B-Square or Weaver that preclude the use of your iron sights. Even an inexpensive laser like this BSA LS650 will work on a mount over the top. If you think he wants some other kind of sight, a good red dot starting with something like a Tasco PDP2 can be used instead of iron sights.
