Hi all,

I'm looking to put a Trijicon 407/507k RDS on my VP9SK and wanted some input regarding backup sight heights.

According to Jagerwerks, for the 407/507C (I believe it's a little larger), they recommend the following:

For lower 1/3rd Co-Witness you would need a VP9 .405"
Dawson Precision HK VP9 Fixed Carry Black Rear Sights
For the front sight you would need a VP9 .295"
Dawson Precision HK VP9 Black Front Sights

reference link: HK VP9 Holosun 407C/507C/508T

Is there a difference in the optic height for the 507c vs the 507k?

Also, I wanted a Fiber Optic Front Sight instead of the black sight. They have a .265" and .365" front optic. The rear is available in .325" & .375" - Which combination here would work better? .265" or .365"?

It is a Dawson Rear .405" tall and a Dawson Front .295" tall.

The .265" front and .375" rear would be a good height combo.

Informational. Going with .265/325.
