The box, manuals, and original accessories are much more important with a "collectible" firearm than with a run-of-the-mill, working gun. That said, they are ALWAYS worth something. Even if the gun isn't a collectible, the absence of those things may reduce the pool of potential buyers. I don't regard a Wilson CQB as a collector firearm, but rather a "working" firearm. How much value the original packaging and manual might be worth is up to you.
