Questions & Answers
Does it fit the glock 30 SF If not please help with the smallest most discreet laser that will work with a AIWB Kydex holster. Thanks Kevin Born Expert Answer

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.

Nice design with excellent fit. Very easy to install. Small, easy to turn on/off. Laser very bright. Great bang for the buck. Battery life okay but could be better. Looks like a factory part. Blends in well the gun.

The laser works perfect and can be used for different scenarios (range, self defense ) my only stipulation if used on a carry gun you might need a specialty holster becuze my iwb and owb don't fit the laser attached.
