While we strive to ensure each and every holster we produce will be ready for service the moment your receive it, some holsters may require a bit of break-in before they are ready for use.
You should never pull a brand new holster out of the box, insert your carry gun, then walk out the door with an un-tested holster. We recommend wearing your holster with its corresponding firearm in safe, comfortable surroundings (we assume this would be your home...). Give the holster a chance to form-fit to your firearm. Practice drawing the weapon until you are comfortable with its retention.
If the holster is still too tight at this point, place the gun in a baggie (like a sandwich bag, or zip-top bag), then insert the gun into the holster. Let it set for a minute or two, then remove the gun and take it out of the bag. Reinsert the gun and see if the retention is to your liking. If not, repeat this process until you're happy with the retention. Do not add any oils to your holster to soften it up, as this could over-soften the leather and damage the holster.
