The FN 509™ is built on the proven architecture of the FNS™ Compact, FN made changes internally and externally to meet the rigorous performance standards of the MHS requirements and further developed the platform into the FN 509 with the help from industry experts. Over the course of development, the platform has been tested extensively for reliability, ammunition compatibility and durability – totaling more than one million rounds.


Esthetic changes to the platform include the aggressive cocking serrations, enhanced grip textures, guarded controls and recessed target crown on the barrel. Critical internal components were completely redesigned to ensure maximum performance to meet FN’s demanding standards.

We started Modern Warriors and Alice Firearms for the sole purpose of providing a less expensive way to enjoy our love of buying and shooting some really cool stuff. What started as a hobby has turned into a business where we have developed the experience and ability to help you enjoy our same hobby and save you money in the process.

We specialize in tactical weapons, including suppressors, short barrel rifles and full auto weapons. We have routine experience in shooting the weapons we carry, so if you want our opinion on how a weapon operates, we will gladly provide it. We also have expertise working with licensed professionals in setting up gun trusts, which is an ideal way of purchasing, owning and operating any weapon restricted by the National Firearm Act. Don’t let the word “trust” scare you. It is very easy to set one up if you have the right help.
