Agency Arms was the original custom slide maker that people remember back in the day. Agency Arms first come up with custom Glock builds that went popular online with that signature "A" milled on the side of the slide.

Use Different Optics - The AOS system allows different optic plate with screw index posts to mount on the slide for different footprint red dot sights other than the Trijicon RMR.

More Secure Optic Mount - Screw index posts lock in the optic tight, which gives the thread more room & depth to secure the optic

FAQ

Does The Serial Number On The Custom Slide Has To Match The Frame?

The serial number on the slide doesn't have to match the one on the frame. In fact, most custom slides don't come with serial number like the OEM Glock slides.

You can still buy custom slides if you live in states that only allow the conceal carry holder to carry the firearm they have registered. 

Where To Get Firing Pin Channel Liner?
