Best Holster Wedge Setup for Glock 19 AIWB Carry: Complete Guide

A Glock 19 holster wedge is the single best upgrade for comfortable, concealed AIWB carry. Here is the complete setup guide.

Why Your Glock 19 AIWB Setup Needs a Holster Wedge

Carrying a Glock 19 in the appendix position (AIWB) is one of the most popular concealed carry methods. However, without proper adjustments, the grip can print through clothing and the muzzle may dig into your thigh. A holster wedge solves both issues by tilting the grip inward toward your body while pushing the muzzle away from your leg.

Whether you carry with a holster wedge for the first time or you are upgrading your current setup, this guide covers everything you need to know about optimizing your Glock 19 AIWB carry with the right wedge configuration.

What Is a Holster Wedge and How Does It Work?

A holster wedge is a foam or rubber attachment that mounts to the back of your IWB holster shell. It creates a pivot point that leverages your body’s natural contours to tuck the firearm’s grip closer to your torso. For Glock 19 carriers, this is especially important because the G19’s grip length can be challenging to conceal without assistance.

The wedge works by applying pressure against your lower abdomen, creating a fulcrum effect. This rotates the top of the slide and grip inward, dramatically reducing printing under a T-shirt or button-down.

Best Wedge Placement for Glock 19 AIWB

Wedge placement varies depending on your body type and holster brand, but for the Glock 19 in AIWB, these positions work best:

Lower Muzzle Area (Most Common)

Placing the wedge near the bottom of the holster shell, just above the muzzle end, provides maximum grip tuck. This is the go-to position for most AIWB carriers and works well for slim to average builds.

Mid-Shell Placement

For those with a larger midsection or who carry slightly off-center, a mid-shell wedge balances comfort and concealment. It reduces muzzle pressure on the thigh while still tucking the grip.

Dual Wedge Setup

Some advanced carriers use two wedges — one at the muzzle and one near the trigger guard area. This creates even pressure distribution and is ideal for all-day carry comfort with the Glock 19.

Step-by-Step: Installing a Wedge on Your Glock 19 Holster

Follow these steps to get the best results:

1. Clean the holster shell — Wipe down the back of your holster with rubbing alcohol to remove oils and dust. Let it dry completely.
2. Position the wedge dry first — Hold the wedge in place without removing the adhesive backing. Put the holster on and check comfort and concealment in the mirror.
3. Mark your spot — Use a small piece of tape or marker to note the ideal position.
4. Attach the wedge — Peel the adhesive backing and press firmly onto the marked position. If using Velcro-based wedges like the Cloudster Pillow, attach the hook side to the holster first.
5. Test and adjust — Wear the setup for 30 minutes around the house. Adjust up or down by half an inch if needed.

Glock 19 AIWB Wedge Setup Tips

• Ride height matters: A higher ride height combined with a wedge tucks the grip even more. Experiment with your holster clip position.
• Belt tension: A sturdy gun belt keeps consistent pressure on the wedge. Flimsy belts reduce wedge effectiveness.
• Claw + wedge combo: Pairing a concealment claw with a wedge is the ultimate AIWB concealment setup for the Glock 19. The claw leverages the belt to push the grip in, while the wedge handles the rotation from below.
• Body type adjustments: If you have a larger midsection, try a thicker wedge. Leaner carriers may prefer a thinner profile.

Common Mistakes to Avoid

• Wedge too thick: An oversized wedge can push the holster too far from your body, creating a different kind of printing.
• Wrong position: Placing the wedge too high negates the leverage effect. Start low and work up.
• Skipping the test fit: Always dry-fit before committing with adhesive.
• Ignoring the holster cant: Wedge angle and holster cant work together. Adjust both for the best result.

Frequently Asked Questions

Do I need a wedge for Glock 19 AIWB carry?

While not strictly required, a wedge significantly improves concealment and comfort for most Glock 19 AIWB carriers. The G19 grip length makes it one of the firearms that benefits most from a wedge.

What size wedge works best for a Glock 19?

A medium-sized wedge (approximately 1/2 to 3/4 inch thick) works well for most people carrying a Glock 19 AIWB. Start with a medium and adjust from there.

Can I use a wedge with a Glock 19 sidecar holster?
