Blackhawk 40LP03BK TecGrip IWB Size 03 Black Nylon Compatible w/Glock 17/Colt 1911 5"/S&W M&P/Sig P320 Ambidextrous

The Blackhawk TecGrip IWB Size 03 is a moldable inside-the-waistband holster built for shooters who want custom fit without custom pricing. Unlike rigid kydex or one-size-fits-most nylon, this holster ships with everything you need to heat-mold it directly to your gun—whether that's a Glock 17, Colt 1911 5", S&W M&P, Sig P320, or any handgun in the Size 03 category. If you've struggled to find an IWB holster with genuine retention and all-day comfort, the TecGrip's layered construction and ambidextrous design solve both problems without forcing you to choose between them.

The molding process is straightforward: use the included dunk bag to heat the holster to temperature, place your gun in the Memory-Lok material, let it cool, and you've got a custom-fitted holster with passive friction retention. The tacky outer layer grips your body and waistband with enough hold that you won't need a belt clip—a real advantage if you're carrying off-duty or in situations where you want zero hardware visibility. The interior is lined with tough 600 denier polyester that resists the friction wear common in cheaper nylon holsters, so your gun and holster both stay in shape after months of carry.

A low-profile shirt guard keeps fabric out of your way, and the sight track is cut for optics—if your P320 or M&P is running a red dot, this holster won't fight it. Ambidextrous design means you can mold it for strong-side or appendix carry without buying two holsters. It's not fancy, but it's honest gear built around a real problem: finding one holster that actually fits your gun and stays put.

Frequently Asked Questions

Will the TecGrip holster work with my Glock 17 or other specific handguns?

Yes. The TecGrip Size 03 is compatible with Glock 17, Colt 1911 5", S&W M&P, and Sig P320. You mold it to your exact gun, so it'll fit snugly. If you own multiple guns in different size categories, you may need a different size holster.

How do I mold the holster to my gun?

The kit includes a T-Handle molding tool and a heavy-mil dunk bag. Heat the holster in the bag until it reaches optimal temperature, then place your unloaded gun into the Memory-Lok material and let it cool. It's designed to be as simple as molding a sports mouth guard.

Can I use the TecGrip with a red dot sight on my pistol?

Yes. The sight channel is low-cut and optimized for mounted red dot optics, so your setup will work without interference.

Do I need a belt or clip to carry this holster?

No. The tacky exterior material clings directly to your body and waistband fabric, providing secure no-clip carry. Of course, you can still wear a belt for overall support and comfort.
