If you have prime this one is cheaper I guess. And it has a real handle which is nice.

I put the standard trijicon 3 dots on my glock 19. You're in a hurry so this won't be much help but for anyone else who's interested in Trijicons they are sold on amazon. If you use camelcamelcamel and set a pricewatch you can save some $$$.

I bought mine when they dropped to $65.

You can also install the sights yourself if needed. I used this tool and some locktight on the front.

And for the back I padded a friends vise and grabbed the slide and tapped it out with a cheap brass punch set from harbor freight.

Or you can use a hammer and punch for rear sight. Secure it in a wise and gently tap it out.

If you haven't already bought one, this is what I got. It's a much better bargain than the 30 dollar Glock sight tool. http://www.amazon.com/gp/product/B000O5ILUM/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

Get the sight pusher if you think you might own more than one Glock or if you might want to experiment with a couple different sight setups.

I've got one pretty much like this and it's more than paid for itself.

Edit - There's also this one for the front sight. I have this, but it was really too deep for me, so I filled most of the socket with Gorilla Glue and it's perfect now.

I couldn't find an adapter online, they usually come with cases. Here's a full tool though. https://www.amazon.com/Wiha-26547-Precision-Driver-Inch/dp/B000O5ILUM
