Finding a concealed carry bag that truly fits your firearm is about more than just dimensions. The right fit protects your trigger, improves draw speed, and keeps your bag balanced and comfortable throughout the day. A good match should feel effortless like your firearm and your bag were designed for each other.
Here’s how to make sure the bag you choose fits perfectly and functions safely.
1. Measure your firearm accurately
Start by taking a few key measurements.
-
Measure the overall length from the back of the slide to the muzzle.
-
Measure the height from the bottom of the grip to the top of the slide or optic.
-
Measure the width at the widest point, including lights or threaded barrels if you plan to carry them.
-
Record these three numbers to compare them with the bag’s specifications.
2. Check the bag’s pocket and holster dimensions
Every brand’s interior layout is different, so dimensions matter.
-
Look for internal pocket or holster measurements on the product page.
-
If they aren’t listed, ask customer service for the exact height and length of the concealed compartment.
-
Leave a small clearance so the firearm slides in easily but doesn’t move around.
3. Use a custom Kydex holster
This part is essential for safety.
-
A custom Kydex holster made for your firearm make/model, and any accessories, keeps your firearm in one stable position and prevents the pocket from collapsing.
-
Avoid loose or universal holsters that shift during movement and may expose the trigger.
4. Account for accessories and how you carry
Your setup changes your fit.
-
Measure your firearm with optics, red dots, or weapon lights installed if you use them.
-
Think about how you wear the bag. Crossbody and sling styles change the firearm’s angle and grip placement.
5. Try before you commit when possible
Nothing replaces a hands-on test.
-
Insert your unloaded firearm or a training gun and wear the bag while walking, sitting, and reaching.
-
Confirm that the trigger stays fully covered and the draw motion feels natural.
-
The goal is a secure fit that doesn’t fight you when it’s time to draw.
6. Plan for future changes
A little flexibility goes a long way.
-
If you rotate between firearms, size your bag for the largest one you plan to carry.
-
Choose a bag with modular or interchangeable holster inserts so you can adjust as your needs change.

FAQs: Finding the Right Fit for Your Firearm
How do I know if my firearm will fit before buying a bag?
Start by measuring your firearm’s length, height, and width, including any accessories you plan to carry. Then compare those numbers to the bag’s internal pocket dimensions or the listed holster size. If the brand doesn’t provide measurements, ask before purchasing. The right fit should feel snug but never tight.
Should I measure with my optic or light attached?
Yes. Always measure your firearm exactly as you carry it. Optics, lights, and extended barrels can add size that changes how the firearm sits inside the bag. Measuring with your full setup prevents surprises when your bag arrives.
What happens if my firearm is too small for the pocket?
A firearm that moves around inside the compartment can slow your draw and compromise safety. Use a fitted Kydex holster or spacer system to keep it secure and in the same position every time.
Is it okay to use a universal holster?
No. Universal holsters often shift or collapse, which can expose the trigger or change your draw angle. A custom-fit Kydex holster provides consistent retention and stability, protecting both you and your firearm.
Do I need a different bag for each firearm?
Not necessarily. Many Zendira bags are designed to work with interchangeable holster inserts, allowing you to switch firearms without buying another bag. Just make sure the new setup maintains the same level of trigger coverage and retention.
What if I carry a larger firearm?
Choose a bag that comfortably fits your largest firearm and allows for smooth draw motion. Bags like Zendira’s Saturday Concealed Carry Bag accommodate full-size handguns while maintaining balance and comfort.
Should the firearm fit tightly in the holster?
It should fit securely enough that it doesn’t move when you shift or bend, but not so tight that you have to fight the draw. A properly fitted Kydex holster gives you just the right balance of stability and speed.
How do I check retention and safety once the firearm is in the bag?
After inserting your unloaded firearm, gently shake or tilt the bag. The firearm should stay in place without rattling. Then, practice drawing to ensure the holster releases smoothly and safely every time.
