Wonder how to paint a Glock slide? There is no doubt that the Glock pistol is now the most popular handgun in America, and for many good reasons. It’s light, simple, and durable. It has low recoil, is resistant to rust through the manufacturer’s patented teniferation process, and features a unique safe action system. Plus, the Glock has its own unique brand of beauty.
However, because the Austrian-made pistol is the standard issue for the country’s law enforcement in addition to being the civilian user’s favorite, making the Glock stand out can become a challenge. The quick, cheap and simple way to personalize your pistol is by painting the slide. There are a number of additional methods you can use following these steps, including employing your own custom stencils. But the key to a custom handgun painting is not mucking up your hardware. Here’s how.
How to Paint a Glock Slide
Step 1. Break Down the Slide
Break down the slide making sure all the attached pieces are removed, such as the barrel, recoil spring assembly, firing pin, spacer sleeve, firing pin spring, spring cups. For the sights, see Step 5.
Step 2. Clean with Alcohol
Clean the inside with 91% (or higher) isopropyl alcohol. You can get this at any drugstore and most grocery stores. Don’t use cheap paper towels or anything else that will leave a gunky residue.
Step 3. Tape the Slide
Tape the bottom portion of the slide, particularly from the grooves of the side rails so that the gun paint will not affect the slide’s movement. The same goes for the channels.
Step 4. Tape the Sights
Tape off the sights carefully. Not even a master marksman could place a shot with a paint-clogged sight.
Step 5. Sand Lightly
Sand the surfaces lightly to help the paint stick. This takes a little practice as you don’t want to sand too hard.
Step 6. Clean Outer Slide with Acetone
Clean the slide’s outer surface with acetone. You want to make sure you get every bit of sanded dust off, otherwise, your paint job could look muddled.
Step 7. Heat Slide at 150 Degrees Fahrenheit
Heat the slide in an oven at 150°F for 5 to 10 minutes. The key here is you don’t need a ton of heat, but if you are unsure about the settings on your oven, make sure you plop in a thermometer in there beforehand. Don’t push it much further than 150 on this step.
Step 8. Hang and Spray
Use a strand of paracord or thick string and tie it around the hole for the recoil spring. Use the paracord to hang the slide. Spray it down with your paint of choice. Just make sure you are using a paint rated for the surface of your gun. Auto shops are a great place to find this kind of paint for cheap.
* Several thin coats give better and lasting results than a single thick coat. If possible, put the slide back in the oven for the same temperature and duration as indicated in Step 7.
Step 9. Let Dry
After 6-7 paint coatings, let the slide dry for 1-2 hours and remove the tape. Don’t use it for a few days.

That’s all there is to painting a Glock slide. All it needs is knowledge of disassembling a Glock, cleaning the inside surface to prevent slide issues, and carefully taping surfaces excluded in the paint job. Let dry and enjoy your Glock’s new look!
