Why Modify a Firearm?

Here at Agency Arms, we take great pride in modifying your personal weapon, to create some of the smoothest shooting, and reliable modified firearms in the world. All of our modifications are performance oriented and developed with this in mind.


How do I get an Agency Arms modified firearm?

Currently Agency Arms specializes in modifying personal pistols, sent in by customers. Our process is very simple! Fill out a Work order online HERE then choose your payment method (We have an awesome 50-50 plan!), send us your gun via UPS or FEDEX to our address:
Agency Arms
2111 Portola Road Suite B
Ventura, CA 93003

You can also ship in your firearm through your local FFL. When we receive your gun, we will log it into our books and disassemble it looking for any aftermarket parts or accessories (We will put these in a bag for you), after a day or two we will give you a call to confirm your build, then we will get your gun started!

 You can also check one of our stocking dealers to purchase a complete build that has been modified by Agency Arms.

Do you guys sell guns? Can I buy a gun from you guys?

At this time Agency Arms does not sell any firearms, but we work with some great dealers to offer built guns, without the lead times! Check them out HERE!


What firearms do you guys work on? Can you work on my XD/M&P Etc.?

Currently Agency Arms specializes in the modification of Glock® pistols, Smith & Wesson® M&P pistols, and the FN® 509. However, we hope to expand to other platforms in the future.


Is there any way I can expedite my orders lead time?

In the spirit of being fair to all our customers, we do not allow any type of expedited delivery. Thank you for understanding
