Description
The Blackhawk TecGrip FormLok is built for people who struggle to find an off-the-shelf IWB holster that actually fits their gun. Instead of buying multiple holsters or settling for poor retention, you get to mold this one to your specific firearm. Size 06 handles compact semi-automatic pistols like the Glock 19, SIG P320 Compact, S&W M&P Compact, and similar frames.
What Makes the TecGrip Moldable
The core material is called Memory-Lok, a thermoformable plastic that softens when heated. You'll drop the holster into the included prep bag, submerge it in 155-175 degree water for about 8 minutes, then mold it around your unloaded gun just like you would a football mouth guard. Once it cools, it holds that shape permanently while staying slightly flexible. This means you get a custom fit that rivals expensive leather or Kydex holsters, but you only pay once.
Building Retention and Comfort Into the Design
The layering is smart. On the outside, a tacky grip material clings directly to your skin and clothing fabric, which is why this works without a belt clip. Underneath that is high-density closed-cell foam padding that keeps you comfortable through a full day of carry. The middle contains that Memory-Lok plastic you molded to your gun. The interior is lined with friction-resistant 600 denier polyester that won't chew up your pistol's finish and will last through countless draws.
Practical Features
Every TecGrip FormLok ships ambidextrous, so left or right hand carry works straight out of the box. The low-profile shirt guard keeps the top of the holster from printing, and the sight channel is cut low enough to accommodate red dot optics if you run them. The kit includes everything you need: the holster, a T-handle molding tool to form the sight track, and a heavy-mil prep bag for heating.

Frequently Asked Questions
How do I mold the TecGrip FormLok to my gun?
It's simple. Place the holster in the included prep bag, submerge it in water heated to 155-175 degrees for about 8 minutes, then carefully mold it around your unloaded pistol. The T-handle tool helps you form the sight channel. Once it cools, the shape sets permanently. Most people get it right the first time, and you can remold it later if you change guns.
Will this holster work without a belt clip?
Yes. The tacky exterior material grips your skin and fabric directly, so there's no clip to fumble with. It stays put through normal activity, though like any clipless holster, you'll want properly fitted pants and shouldn't expect it to hold up if you're doing hard running or dynamic movement without reinforcement from your waistband.
What if my gun is slightly different from the listed compatible models?
Size 06 is designed for compact semi-automatic pistols, roughly the size of a Glock 19. If your gun is within that general frame size and you follow the molding instructions carefully, you should get a solid fit. Check the Blackhawk size chart to confirm your specific model fits within Size 06 dimensions before ordering.
Can I use this with a mounted red dot?
Yes, the sight channel is cut low to accommodate mounted red dot optics. There's also some space in front of the trigger guard for small devices like a laser, though larger light units likely won't fit in the Size 06.
