Hey Everyone!

I’ve been away from the blog for a while due to carpal tunnel, but thanks to many improvements and much rest I think I can begin easing back into the blog.

To start things off, I just wanted to make a quick blog post discussing where you can get rails for your 3D printed glock frame. If you’re unfamiliar, let me provide a bit of backstory:

Free Men Don’t Ask’s Revolutionary Glock Frame

Before the FMDA Glock frame we all know and love, the thought of printing a reliable Glock lower was all but a dream. The slide needed to interface with metal rails or it’d fly off back into your face. This presented a challenge for 3D printing a frame, but one that FMDA overcame with some clever engineering.

On any of the FMDA based Glocks, the lower includes cavities in order to facilitate drop in metal rails. These result in a 3D printed frame that’s reliable and still fairly DIY-able.

How are the rails made?

Great question! The rails are made of Aluminum in most cases, and current examples have withstood 2k rounds of use with no detectable wear. They can be milled/filed out of simple bar stock with all measurements and jigs provided in the files. But, and understandably, you may want a more readily available solution.

Where to Buy Premade Rails for 3D Printed Frames

If you’re looking for an already cut set of rails for your 3D printed frame there are a few providers:

  1. Spooky Rails: Spooky Rails is the original provider of rails for 3D printed frames, and has G17, SD9, and G26 rails available for sale.
  2. Aves Rails: For a while, Spooky Rails had trouble meeting demand and people couldn’t get rails. Aves stepped up and began offering G17, G19, and G26 rails. Slightly cheaper than Spooky Rails and with included hardware, it’s an excellent option!
  3. Riptide Rails: Riptide Rails creates rail kits in house with solid pins that can be pushed by hand, and pre-ground screws, resulting in sets that are ready to install. I’ve not had any personal experience with the rails, but the owner ships them in printed Rail Blocks to both protect them during shipping and act as a quality control check. Also likely a great option for sourcing rails, especially if you don’t want to grind the screws down.
