Beretta mount needs to be drilled to mount. - Sight Gunsights Red Dot Sight Mount

I recently purchased the mount for my px4 storm thinking this mount was just a simple dovetail mount. I misread when ordering this mount. The front of the plate needs to be drilled. Cost me $25 for drilling and installation. I am happy with this mount because it feels stronger then a simple dovetail mount. I will most likely order this on other weapons in the future.
