Description
The Appendix Carry Design System: Engineering Concealment, Comfort & Speed for the Most Demanded Carry Position
AIWB isn't just another position — it's a design philosophy. Learn the engineering that turns an "AIWB holster" into a concealment system customers trust with their lives.
---
You can make holsters. Your IWB designs get positive reviews. But when customers ask for appendix carry options, you hesitate. You know AIWB is different — more demanding, less forgiving — and you don't want to sell something that fails where it matters most.
The DIY videos show you basic shaping. The forums argue about claw placement. But nobody's teaching the ENGINEERING behind professional AIWB design:
Why some claws work and others don't
How wedge geometry affects concealment physics
The body mechanics that make or break comfort
Why ride height is more critical in AIWB than any other position
How to design for sitting comfort (where most AIWB holsters fail)
Meanwhile, competitors charging $120-180 for AIWB rigs are capturing the premium market you can't access.

The Appendix Carry Design System is the definitive technical guide to engineering professional-grade AIWB holsters. Written by Kobra Holsters, this isn't basic pattern-making — it's applied design engineering for the carry position that demands the most from holster makers.
This guide assumes you already know how to make holsters. It teaches you how to DESIGN for appendix carry — the physics, the body mechanics, the concealment geometry, and the failure modes that separate amateur work from professional systems.

PREREQUISITE: YOU SHOULD KNOW
This is NOT a beginner guide. You should already understand:
Basic Kydex forming and shaping
Standard IWB holster construction
Hardware installation (eyelets, clips, screws)
Basic retention concepts
If you're new to holster making, start with The Complete Kydex Holster Crafting Guide first.

WHY LEARN FROM KOBRA HOLSTERS?
We've built appendix carry holsters for the full spectrum of customers:
Law enforcement officers who sit 8+ hours in vehicles
Military personnel who need active-movement security
EDC enthusiasts who demand "invisible" concealment
Plus-size customers that most designs fail
Female carriers with different body geometry needs
We've iterated through design failures so you don't have to. Our AIWB designs pass the tests — sitting, concealment, retention, and durability — that amateur designs fail within days.

FREQUENTLY ASKED QUESTIONS
Q: Is this just for Kydex?
A: The principles apply to any AIWB holster material, though examples and techniques focus on thermoplastic construction.
Q: Will this teach me basic holster making?
A: No. This builds on existing skills. If you're new to holster making, start with our Crafting Guide.
Q: Does this include CAD files or patterns?
A: No physical patterns. This teaches you to DESIGN and ENGINEER your own AIWB systems — the thinking behind the specific measurements.
Q: Can I use this for commercial production?
A: Yes. Everything in this guide is for your use in your own holster business. No licensing fees or attribution required.
Q: What about sidecar/magazine carriers?
A: Full chapter on sidecar design, attachment methods, and spacing optimization.
Q: Does it cover light-bearing AIWB?
A: Yes. The specific challenges of concealed carry with weapon-mounted lights — wider footprints, retention points, and wedge requirements.

READY TO MASTER AIWB DESIGN?
The appendix carry market keeps growing. Customers are willing to pay $100-180 for quality AIWB systems — but only from makers who understand the engineering.
Every month you spend guessing at claw placement and wedge sizing is a month of not commanding premium prices.
