Why Holster Fit Matters
A poorly fitting holster is more than uncomfortable — it can slow your draw, cause printing, and even create a safety hazard. Whether you're new to concealed carry or switching to a custom Kydex holster, getting the fit right is the single most important decision you'll make.
This guide walks you through everything you need to know to find a holster that fits your firearm, your body, and your carry style.
Step 1: Match the Holster to Your Exact Firearm Model
Holsters are not one-size-fits-all. A holster designed for a Glock 19 will not properly retain a Glock 17, even though they look nearly identical. Always match the holster to your specific make, model, and generation.
Key things to confirm before ordering:
- Make and model (e.g., Glock 19 Gen 5, Sig Sauer P365 XL)
- Barrel length — especially important for revolvers and long-slide pistols
- Optics — if you run a red dot, you need an optic-cut holster
- Weapon lights or lasers — these change the holster footprint significantly
Our custom holsters are built to your exact firearm configuration, so you never have to guess.
Step 2: Choose Your Carry Position
Where you carry on your body directly affects which holster design will fit you best. The most common positions are:
- 3 o'clock (strong side) — the most natural draw, great for OWB carry
- 4–5 o'clock (behind the hip) — popular for IWB, balances concealment and access
- Appendix (AIWB, 1–2 o'clock) — excellent concealment, fast draw, requires a holster designed for AIWB
Your body type, clothing style, and daily activity level all influence which position works best. Taller or slimmer carriers often find appendix carry more comfortable, while those with a larger midsection may prefer strong-side or behind-the-hip carry.
Step 3: Understand Retention
Retention refers to how securely the holster holds your firearm. For concealed carry, you want passive retention — the holster holds the gun through friction and fit, with no buttons or levers to disengage.
Kydex holsters excel here because the material is molded precisely to your firearm. A well-made Kydex holster should:
- Hold the gun securely when you shake or invert it
- Release cleanly with a consistent, audible click on re-holster
- Allow a smooth, snag-free draw with one hand
Retention that is too loose is a safety risk. Retention that is too tight slows your draw. A custom-molded holster hits the right balance out of the box.
Step 4: Check the Ride Height and Cant
Ride height is how high or low the gun sits relative to your waistband. A higher ride height makes the grip more accessible; a lower ride height aids concealment.
Cant is the angle of the holster. A neutral (0°) cant works well for strong-side carry. A forward cant (FBI cant, around 15°) is popular for behind-the-hip IWB carry because it tilts the grip forward for a more natural draw.
If you're unsure, start with a neutral cant and adjust from there based on your draw stroke.
Step 5: Test the Fit Before You Carry
Once your holster arrives, do a dry-fire fit check before carrying:
- Ensure the firearm is unloaded and the chamber is clear
- Insert the firearm into the holster — it should seat fully with a click
- Shake the holstered firearm — it should not move or rattle
- Draw slowly and check for any snags on the trigger guard or sights
- Re-holster and confirm the trigger is fully covered at all times
Never rush the re-holster. Take your time, look the holster into position, and ensure nothing (clothing, fingers) is in the trigger guard.
