Defender ccw for ruger american pistol competetion - Vortex Defender-CCW 1x25mm Reflex Red Dot Sight

Just got the Defender CCW 3 moa mounted on my Ruger American Pistol Competition model. It fits great and wanted to pass on what I did for other Ruger American Pistol Competition owners. I was replacing an older Vortex Viper Red Dot and wanted a Red Dot with the auto on/off/awake features. I looked at the Defender ST and XL but their foot prints were to long so I decided to try the CCW.

I removed the optic mount cover plate and the two alignment pins. That allows the Defender CCW to sit in the machined slot for the optics. I talked with Vortex Support and they confirmed that you don't have to use the alignment pins for securing the optic to the slide and that the two mounting screw's will be fine. The Vortex Defender CCW fits snug to the front of the factory machined optic slot with space behind the glass. I used the 1 degree plastic shim so the CCW wouldn't need as much elevation adjustment. The provided 6 x 48 x 9mm long screws were a little short, so I purchased from a local Ace Hardware 6 x 48 x 10 mm long gun machine screws to mount the CCW. The provided 6 x 48 x 9 mm screws only had a few threads showing with the shim and CCW optic stack up.

I have dry fired a couple hundred times and and live fired 50 rounds. So far the Defender CCW is holding steady.
