Crimson Trace has issued a Safety Recall on certain lasers. It was discovered that lasers produced between 11Mar2016 to 11Oct2017 have a bubble in them. This only effects certain models, some that are integrated and those that are not. Crimson Trace has set up a website to determine if you have an affected laser. If you do, you will follow the steps to return the affected one and receive a new one.
You must go through this site to return your laser. Do not return it to the dealer you bought it from.
