We're pleased to now offer a simple solution to creating light channels in your holsters. These widgets are made of super tough nylon that will not chip or break and will withstand temperatures up to 500 degrees. We have milled these out so that they will cover the controls of most lights and clear the grip of most pistols. You might need to trim them a little for your specific project, but we've found they will work great on Glocks, S&W M&P's, Sigs and XD pistols. They will work great with Streamlight TLR, Surefire X-series and most Insight lights. Simply tape or glue them in place and you're ready to make functional, professional looking holsters yourself. Sold as matched sets.
