Colorado Gun Works: Home
They are a warranty shop for Bersa/Firestorm firearms.
Please write or type a letter explaining the problem. Make sure to include a physical address and phone number. Dis-assemble the firearm like you were going to clean it. Wrap the parts separately to prevent damage in shipping, and place them all in one box.
Address the box to:
CGW
2631 W. Vine Drive
Ft. Collins, CO 80521
This prevents the word gun from being on the outside of the box and inviting unwanted attention. Take it to UPS or FED EX and ship it as PARTS! This will save you money, and is in no way a violation of any law. Shipping handguns overnight is a company policy to make it tougher and more expensive for you and it is not fair. Use our directions and you will save money and time.
If you have any further questions regarding shipping your firearm in for warranty repair, call (970)482-4867 and talk to Royce.
