I decided to install an EGW dovetail mount for a DP Pro on a VP9B, to serve as an additional back-up pistol, given my track record killing red dots. Sounded good in concept, but once I got it on, it was hideously high, and actually made an Acro seem petite.
I quickly removed it and installed Night Fission sights on the slide and will check their zero later today. They seem like nice sights but the rear is sharper than I would prefer. Dimensions seem the same as OEM, and one idea is to combine an OEM tritium rear with the Night Fission front.
