This seems to be a conundrum, I would suspect how the polymers are combined with other materials/chemicals such as glass and glass doesn't deteriorate, UV is a none issue because it's either in a holster, safe, Armory, Gun Case, under pillow, mattress, couch etc... unless you keep it on the roof of your house everyday or wear it as a hat??? I don't see any indication that UV exposure would effect the polymer material. You don't have the slides acutally seeing allot of wear when there is mostly steel/metal inserts always noted in the condstruction to note it as a sales pitch. Can't compare to the automotive plastics because there designed for impact absorbsion. I really don't think it's a real issue as long as you take care of it...
