Upgrading your Glock with a switch gives you unmatched firepower — but that performance comes with responsibility. A Glock with a switch requires more precise, consistent maintenance to remain reliable, safe, and durable over time.
Why Maintenance Is Critical for Switched Glocks
Unlike factory Glocks, a Glock fitted with a switch introduces more complexity to the firing mechanism — especially when full-auto mode is in play. The intense rate of fire increases wear, carbon buildup, and heat.
Neglecting maintenance can cause:
- Firing malfunctions or jams
- Premature wear of sear components
- Unstable auto-fire or trigger lag
- Safety concerns due to misalignment
Regular upkeep isn’t optional — it’s essential.
The Real-World Impact: A Cautionary Story
A customer at AutoSear.org once reported his Glock 19 switch jamming mid-fire. After some troubleshooting, we discovered it hadn’t been cleaned after a 400-round range session. Heavy carbon fouling had gummed up the switch interface.
Once cleaned and lubricated, it performed like new. That’s why cleaning before and after heavy use is non-negotiable.
Pro-Level Glock Maintenance: Step-by-Step with a Switch Installed
Here’s your essential cleaning routine to follow after every few hundred rounds:
1. Ensure Safety First
- Unload your Glock completely
- Double-check chamber and magazine well
- Keep ammo away from your workspace
Always start maintenance only with a cleared weapon.
2. Disassemble Your Glock
Field strip your Glock as usual:
- Remove the slide
- Extract barrel and recoil spring
- Open the backplate to access the switch mechanism
Use a Glock disassembly tool or a precision punch.
3. Clean the Core and the Switch
Use the following tools:
- Nylon brush or detailing brush
- Cotton swabs for tight spaces
- Solvent (like CLP or Hoppe’s No. 9)
Focus areas:
- Trigger assembly
- Firing pin channel
- Switch contact points
- Slide rails and barrel lug
Carbon buildup loves to hide in the switch cavity — dig deep.
4. Inspect for Wear and Tear
Look closely for:
- Cracks or stress in the switch body
- Rounded edges or discoloration
- Damage to the trigger bar or slide mechanism

5. Apply Targeted Lubrication
Use high-quality firearm oil — apply sparingly:
- Switch contact surfaces
- Trigger connector
- Slide rails
- Barrel lockup area
Avoid excess oil inside the switch mechanism — too much can attract debris and cause drag.
6. Reassemble and Function Test
Once everything is cleaned and lubed:
- Reassemble your Glock
- Rack the slide and dry fire with a dummy round
- Confirm that the switch cycles properly
Smooth cycling? You’re good to go.
Best Practices to Maintain Your Switched Glock
Here’s a quick checklist of habits to adopt:
- Clean every 100–300 rounds, depending on firing mode
- Use Glock-specific cleaning kits
- Store your Glock in a dry, secured container
- Inspect switch parts every other session
- Use ammo with clean burn to reduce carbon buildup

FAQ: Maintaining a Glock with a Switch
Q: Can I use my standard Glock cleaning kit?
A: Yes — but add micro tools or brushes designed to access the switch area.
Q: What’s the biggest cause of Glock switch malfunctions?
A: Carbon buildup, poor lubrication, or worn contact edges.
Q: Should I disassemble the switch every time?
A: Only after heavy use or every few hundred rounds. Routine wipe-downs are fine in between.
