Top 10 Custom Slide Back Plate Designs for Firearm Customization in 2025

Glocks are iconic weapons for a reason. While their most important features are their reliability and their effectiveness, they’re also modular. In addition to making the gun easy to repair, that modularity allows you to swap out those factory parts for aftermarket ones. You can make your Glock your own.

One of the easiest parts to swap is the back plate. There are thousands of aftermarket back plates that feature logos, iconic designs, custom text, and just about anything else you can imagine. That’s a lot of designs to try to wade through to find the right one for you — and that’s why we created this firearm customization guide. Let’s dive into the top 10 back plate designs members of our community have added to their personal handguns.

1. Thin Blue Line

MILSPIN is proud to support the officers who put their lives on the line to keep our communities safe. With our Thin Blue Line back plate being one of our top-selling back plates, we’re happy to see that our customers feel the same. Pay homage to the boys (and girls) in blue with this first responder back plate.

2. Blacked Out American Flag

This tactical back plate for Glocks was made for the patriots who value subtlety in their firearm customization. Add the Star-Spangled Banner to your firearm without disrupting the all-black design philosophy of a factory Glock.

3. F*ck Around Find Out

FAFO back plate design

Sometimes, carrying a gun is just as much about sending a message as it is about self-defense. That’s why we released our F*ck Around Find Out back plate, featuring the iconic Gadsden flag, bold engraved text, and nine different materials.

4. “I’m Your Huckleberry”

I’m Your Huckleberry back plate design

With a line so iconic from a scene so memorable, crafting a back plate for it was a no-brainer. Add that electric confidence to your handgun with a Glock back plate cover that features Doc Holliday’s mustache and famous line engraved with a CNC milling machine into your choice of material.

5. American Flag

No tactical black coating. No extra text. Designed for minimalist firearm customization, our American flag back plate design is a simple engraving of the flag of the greatest country on Earth on your choice of eight different materials.

6. USMC EGA Icon

Whether you’re a marine yourself or just want to show your admiration for the Corps, this back plate was designed for you.

7. Just The Tip

Life’s too short to be serious all the time with your firearm customization. Our Just The Tip back plate gives you a laugh every time you draw your gun — and a warning to whoever forced you to draw in the first place.

8. Tri-Color USA Flag

Minimalist flag back plate designs are a tactical spin on the original, but there’s no replacement for the classic Red, White, and Blue. Our tri-color American flag back plate may lack 43 of the stars and five of the stripes, but it captures the colors that make our flag so iconic.
