If you have a Kydex holster (who doesn’t anymore), you have a solid platform that will hold up well compared to many of the other nylon and leather options out there. They don’t scuff, or need to be babied. You can beat the living daylights out of them. In many ways they are far superior to anything else on the market. Except in one.
Don’t leave the newer versions in your hot car. Many companies have found that thinner kydex works great and conceals well too. They also have created a problem in the summer with people who leave there kydex in the car and have it bake for a few hours. A deformed holster is not cool. Don’t risk ruining your great holster. Take it out of the car.
