Equipping a light or laser to your firearm will require you to use a specific holster (or universal fit) for that specific model laser/light. Email us at Techsales@opticsplanet.com and let us know the specific holster you are using. If it was not intended to be used with a light/laser you will need to purchase a different holster.
