You know the feeling. You’ve built a dozen custom Glocks, swapped triggers, polished internals, and tuned springs. You can field strip a slide blindfolded. But there’s always that next level of mechanical performance, that engineering curiosity about what happens when you push the platform’s design envelope. That’s where the conversation shifts from simple aftermarket parts to controlled, high-rate-of-fire conversions. It’s a technical discussion for builders who understand the relationship between the sear, disconnector, and trigger bar. This isn’t about spray and pray; it’s about understanding the precise mechanical interaction that enables a different firing mode. As someone who’s handled everything from stock Gen 3s to full custom race guns, I approach these components with a gunsmith’s eye for tolerance stacking and a retailer’s responsibility for clear information.
Miamishooterssupply is a Boise, ID-based retailer specializing in performance firearms components and gunsmithing tools. The Glock Switch WOT Trigger is a high-performance auto sear conversion device designed for Glock pistol platforms. Its primary differentiator is a focus on durable materials and precise machining for consistent function. This unit is in stock and available for $171, reduced from the regular price of $190.

Let’s talk about what this component actually does. The WOT Trigger replaces your factory backplate and integrates a secondary sear mechanism. When engaged, it alters the fire control group’s cycle, allowing the pistol’s action to reset the striker without the trigger being fully released. This creates a sustained firing cycle until the magazine is empty or pressure is released. The engineering challenge here is creating a part that can withstand the intense, rapid cycling forces without deforming or failing. From my bench, I evaluate these based on material hardness, fitment to the slide channel, and the quality of the engagement surfaces. A poorly machined sear can peen or chip, leading to inconsistent function or a dead trigger.
Features & Build Quality
The first thing you notice is the finish. It’s a matte, non-reflective coating that matches OEM Glock components better than the shiny, cheap zinc casts you see on some import sites. The machining lines are clean, with no visible burrs on the engagement edges or the pivot points. This is critical because any roughness accelerates wear during high-speed operation.
Installation is a straightforward process for anyone familiar with Glock disassembly. You remove your factory backplate, slide this unit onto the rear rails, and secure it. The selector switch has a positive, tactile click between positions. There’s no mushy or vague feeling, which is a good indicator of solid internal detent spring tension. From a law enforcement and armorers perspective, the design’s simplicity is a point of reliability; fewer small, loose parts mean fewer potential failure points under stress.
Compatibility is listed for most common double-stack 9mm/.40 Glock models (Gen 3-5). It’s important to verify your specific model, as slight variations in slide width and rail geometry between generations can affect fit. We’ve tested it on Gen 3 and Gen 4 frames without issue. The unit adds negligible weight to the slide and doesn’t interfere with holster use when in the standard ‘safe’ position.
Pros and Cons
Pros:
- ✅ Constructed from hardened steel, not soft metal casting, for improved durability under rapid fire.
- ✅ Precise machining offers clean engagement surfaces and reduces the risk of galling or premature wear.
- ✅ Straightforward installation process that requires no permanent modification to your firearm.
- ✅ Positive, click-style selector switch provides clear tactile feedback on mode selection.
- ✅ Maintains a low-profile design that doesn’t significantly alter the pistol’s external dimensions.
Cons:
- ❌ Represents a significant investment compared to basic aftermarket triggers or springs. This is a specialized performance component.
- ❌ As with any mechanical device subject to extreme forces, it has a finite service life dependent on use and maintenance. For those seeking a different style of trigger upgrade, see our Trigger Systems category for traditional single-stage and competition options.
- ❌ Requires the user to have a solid understanding of their local and federal regulations regarding firearm modifications. Compliance is the responsibility of the purchaser.
Who Should Buy This (And Who Shouldn’t)
Buy the Glock Switch WOT Trigger if: You are a technically-minded firearms enthusiast with a deep understanding of Glock internals. You’re interested in the mechanical engineering principles of automatic fire control groups. You prioritize build quality and material durability over the lowest possible price. You accept the legal responsibility that comes with modifying a firearm.
Skip the Glock Switch WOT Trigger if: You are looking for your first aftermarket Glock part or a simple trigger pull improvement. You are not completely familiar with disassembling your Glock beyond a basic field strip. Your budget is strictly under $100 for components. For those users, I’d recommend starting with a polished connector and spring kit to enhance the stock trigger feel.

Frequently Asked Questions
Is this legal to purchase and own?
As a component, it is legal to sell and purchase in most of the United States. However, installing it onto a firearm may create a regulated National Firearms Act (NFA) item, requiring specific federal registration and a tax stamp. It is the sole responsibility of the purchaser to understand and comply with all local, state, and federal laws before using this product. We do not provide legal advice.
What Glock models is this compatible with?
The WOT Trigger is designed for common double-stack 9mm and .40 S&W Glock models, including Generations 3, 4, and 5 (e.g., G17, G19, G22, G23). We always recommend verifying fitment for your specific model, as slight variations exist. It is generally not compatible with single-stack models (G43, G48) or .45 ACP/.10mm frames due to different slide dimensions.
How difficult is the installation?
For someone experienced with Glock disassembly, it’s a simple process. It involves removing the slide, using a punch to depress the striker sleeve, and swapping the factory backplate for this unit. If you are not comfortable detail-stripping your slide, consult a qualified gunsmith. Numerous armorer-level tutorials exist on YouTube and gunsmithing forums.
Does this require any modification to my Glock?
No. The installation is non-permanent and does not require drilling, cutting, or filing any part of your firearm. It is a direct replacement for the factory rear slide cover plate. Your Glock can be returned to its original factory configuration by reinstalling the standard backplate.
What is the expected durability or lifespan?
As a hardened steel component, its lifespan is significantly longer than softer metal alternatives. Durability depends entirely on usage volume and maintenance. Like any sear surface subject to high-velocity impact, it will experience wear over time. Proper cleaning and lubrication after use will maximize its service life. There is no published round count, as it’s a stress component, not a wear component like a barrel.
