16 LAW ENFORCEMENT TECHNOLOGY JUNE/JULY 2019 C O V E R S T O R Y an inch movement in the pocket side to side. Any one of these errors could get an officer killed in a gunfight. This is not to say that you cannot have your slides milled, it just says that you need to work with a reputable machine shop who has done this type of work before. Technology is not fail proof Like any mechanical object, RDS can fail. That means you need a backup plan. In the case of RDS, that backup plan means iron sights. But since an RDS is tall enough to hide normal sights, suppressor-height sights are required. While the optics-ready GLOCK comes with standard-height sights, aftermarket suppressor-height sights are available. The FN 509 MRD and SIG P320 RX come with pre- mounted suppressor-height night sights. With adjustment tools for both the RDS and the iron sights and some quality range time, you should be able to co-witness your primary and backup sights. Horizontal co-witness is manda- tory, but vertical co-witness depends on the shooter's preference That is, the dot should always be centered above the sight picture when the sights are lined up in your line of vision"regard- less of whether the iron sights are in the lowest part of the glass or dead center. There is one failure mode that needs impeccable training"when exiting from an air-conditioned car or building into a humid environment, it is possible that the RDS could fog up. If this happens, both the RDS and the iron sights might disappear. Scott Reidy, director of training at SIG Sauer Academy, says, "To help combat the fogging we apply Rain X or Cat Crap. Additionally, we teach an occluded optics drill that still allows the shooter to see the red dot. And even with a fogged-up sight, the shooter still can place the dot on target if they keep both eyes open." You may not want to install backup iron sights for older personnel until they go through most of their training. Both Pronske and Galli made it very clear that experienced officers spent a lot of time looking through the RDS for their iron sights – enough time to get them killed. Pronske also told me that because of muscle memory, older officers may have trouble trying to find the dot because they treat the RDS as if it was an iron sight needing perfect alignment. They need to remember that an RDS shows up on the target and not at the front of the weapon, like a front sight does. Eliminating the iron sights from the equation can help experienced officers focus on the dot. Once they've built up speed and accuracy, the iron sights can be mounted for final training and qualification. On the other hand, Pronske said that, "new shooters who grew up on videogames tend to lock up if the dot is washed out or the optic has failed. In both cases, substantial training is required to ensure speed and accuracy with an RDS." Reidy says that, "the biggest differ- ence between new and experienced shooters is that train-up is easier for younger shooters"millennials and Gen Z's pick it right up. For shooters over 35 years old, RDS really helps to resurrect their shooting careers." He agrees that training is manda- tory and recommends a minimum of two full days of training before letting officers loose with a RDS. His train- the-trainer agenda can be found at It includes a substantial number of drills pertaining to variable lighting, down optics, bar- riers and holdover/offset due to the " Properly trained…it is a faster sight picture, easier for long range engagements and is more effective in low light than traditional night sights. " — Officer Christopher Galli, Santa Cruz Police Department (Calif.) SIG Sauer's P320RX ships with a factor y-mounted optic, the ROMEO1, designed to ensure faster sight acquisition on target.
