Where to find better pics of pistol sites?

I cant be the only one who gets frustrated with the lack of pictures the site companies give you. It is not that hard to take a picture looking down the sites. So why do they give us crappy pics?

This is what I am trying to find a better look at ... even google images struggles to find good site pics.


What is the best way to get a look at the sites, especially before you drop $130ish on them and hate the look?

These would be going on a glock 17

I guess I am haha my bad
