If you already have a Glock 17, get in touch with Jay from black box customs.
While the photo you've provided is as mentioned, a taran tactical Glock 34, black box can absolutely get you something similar.
It'd be a simple matter of mill work on the slide to suit your preference + the RMR, an oversized magwell, a Surefire weapon light of your choice(your picture shows the XC1 but I'd recommend an x300u) and some frame modifications.
If you wanted to supply your Glock 17, the entire project would probably run you around 1500-2000 but spend some time on BBC's website and you can get an accurate idea of cost.
For what it's worth, the guys at BBC are top notch dudes who put out top notch product. One of the best run companies I've ever dealt with.
