*Update* We took away the added cost of light and now is part of the drop-down selection. All you have to do is find your firearm and light setup in the drop-down. Red dot cuts and suppressor height sight accommodations are standard as well as open-ended to allow for threaded barrels and compensators. If you do not see your firearm and light setup check out our custom holster option for more selections.

You are looking at our Flex  Master Blaster holster! Specially designed for appendix carry.

– All setups come with a concealment wing to help with printing
– Hand Made
– Made from .08″ Kydex
-Two RCS clips to allow for shirt tucking
– They are all set up to accommodate, red dots, most suppressor height sights, and are open-ended to allow for threaded barrels and most compensators.

The Master Blaster is fastened together with a military-grade shock cord and allows the firearm to flex closer into the body independently of the magazine for better concealment. This connection also allows the holster to flex where needed while performing other acts like getting in and out of vehicles and bending over.

If you do not see your Firearm/ Light combo we have a custom holster option that may have what you want. Custom Holster

    After failed attempts at finding a well made, light capable holster I finally found havok. Let me tell you I wear this thing for 8+ hour days and it’s comfortable as hell. Very well made, the fabric is set really nice and it’s held up great! Definitely worth it!!

    Just received my FLEX MASTER BLASTER IWB and boy does it exceed my expectations. Quality, design, and fit is perfect. With the custom print that I got, this beats my other holsters I have for my other guns. Definitely my carry loadout moving forward. I also like the fact that Ben incorporated a wider lip for the mag side.

    Couldn’t be happier with how well this turned out. The fit it spot on, well made and comfortable.
