From a Gunsmith’s Bench: The FRT-15L3 is a Mechanical Puzzle, Not a Magic Wand
I’ve spent over a decade in this industry, and I’ve seen every trigger modification under the sun come across my workbench. Most are gimmicks. The Glock Switch FRT-15L3 Trigger Selector is different. It’s not about making your firearm something it’s not; it’s about unlocking a specific, controlled mechanical function that fundamentally changes your interaction with the platform. This isn’t a drop-in part for the casual shooter. It’s a precision-engineered selector that introduces a third, distinct firing mode—FRT (Forced Reset Trigger)—alongside the standard Safe and Semi-automatic positions. It demands understanding. From my perspective in Boise, handling thousands of parts, the engineering here is what separates a range toy from a serious functional upgrade. Let’s get into the specs.

Miamishooterssupply is a Boise, ID-based retailer specializing in high-performance firearm components and gunsmithing tools. The Glock Switch FRT-15L3 Trigger Selector is a multi-mode selector switch that adds a dedicated FRT (Forced Reset Trigger) function to compatible Glock platforms. Its primary differentiator is a dedicated, positive selector position for the FRT mode, separating it from binary or other trigger systems. Available now for $295.00 with same-day shipping.
Features: A Deep Dive into the Mechanism
The core of the FRT-15L3 is its three-position selector. Safe and Semi are self-explanatory for any Glock owner. The third position, FRT, engages a forced reset mechanism. This isn’t simulated recoil or a software trick; it’s a physical interaction between the selector, the trigger bar, and the disconnector. When engaged, the trigger resets forward immediately after the sear releases, as long as forward pressure is maintained. This allows for a significantly increased rate of controlled fire compared to standard semi-auto operation, but it is entirely mechanical and dependent on the shooter’s finger input. It’s the kind of engineering you see dissected on technical YouTube gun channels, where the focus is on the how, not just the result.
Reliability is non-negotiable. This component is machined from high-grade tool steel and hardened to withstand the repeated, high-stress cycling of the FRT function. A cheaply made part will deform or fail under these conditions, potentially causing a malfunction or out-of-battery event. The finish is a durable, corrosion-resistant coating that matches OEM specs, ensuring smooth operation within the frame without binding. From an armorer’s standpoint, the tolerances are tight where they need to be—around the pivot and detent paths—to provide a crisp, definitive click between modes without any slop or ambiguity.
Installation requires a basic understanding of your Glock’s fire control group. You’ll need to detail strip the frame to replace the factory safety lever. It’s a straightforward job for anyone comfortable with a punch and a block, but it’s not a “no-tools” installation. The selector interfaces directly with the trigger mechanism housing and the trigger bar. Proper installation is critical for safe and reliable function in all three modes. I always recommend function-checking the firearm thoroughly in a safe direction after installing any fire control component.
Pros & Cons: The Honest Assessment
Pros:
- ✅ Dedicated FRT Mode: Provides a distinct, selectable firing mode separate from semi-auto, offering a unique and controlled shooting experience.
- ✅ Precision Machining: Manufactured from hardened tool steel to exacting tolerances, ensuring longevity and reliable function under rapid cycling.
- ✅ Positive Detent Clicks: The selector has definitive stops at Safe, Semi, and FRT, preventing accidental mode changes during handling or firing.
- ✅ OEM-Compatible Finish: The coating is designed to work seamlessly with your Glock’s frame internals, reducing friction and wear.
- ✅ Mechanical Simplicity: No electronics, springs, or complex assemblies. Its function is derived purely from mechanical interaction, which appeals to purists and tinkerers.
Cons:
- ❌ Premium Price Point: At $295, it’s a significant investment compared to standard trigger upgrades. You’re paying for specialized engineering and material quality.
- ❌ Requires Understanding & Skill: This is not a beginner part. Proper installation and a full understanding of its mechanical function are mandatory for safe operation.
- ❌ Niche Application: The FRT mode has a specific use case. If you’re looking for a lighter pull weight for precision shooting, see our performance trigger category for more suitable alternatives.
Who Should (and Shouldn’t) Buy the FRT-15L3
Buy it if: You are an experienced Glock owner and amateur gunsmith who understands fire control group function. You’re interested in the mechanical theory behind forced reset triggers and want a dedicated, selectable option. You prioritize build quality and durability in aftermarket components. You enjoy modifying and testing the functional limits of your firearms in a controlled environment.
Skip it if: You are new to firearm maintenance or uncomfortable with detail-stripping your Glock frame. You are solely seeking a lighter or crisper trigger pull for target shooting (our standard performance triggers are a better fit). Your primary concern is budget over specialized function. You do not have a clear understanding of local laws regarding firearm modifications.

How It Stacks Up: FRT-15L3 vs. The Competition
| Feature | FRT-15L3 (This Product) | Budget Import Selector (~$65) | Premium Brand Binary Trigger (~$275) |
|---|---|---|---|
| Material | Hardened Tool Steel | Soft Aluminum or Pot Metal | Machined Steel |
| Quality | Precision CNC, Tight Tolerances | Cast, Often with Burrs/Slop | High-Quality CNC |
| Compatibility | Glock Gen 3-5 | “Universal” – Often Requires Fitting | Specific to Brand’s System |
| Shipping | Same-Day from Boise, ID | Weeks from Overseas | Varies |
| Lifespan/Durability | Built for High-Cycle FRT Use | Prone to Wear/Deformation | Built for Binary Function |

The comparison shows you’re not just buying a part; you’re buying an application-specific tool. The budget option is a gamble on fit and safety. The binary trigger is a different system entirely (fire on pull and release). The FRT-15L3 occupies its own niche with a dedicated mechanical forced reset mode.
Frequently Asked Questions
Is the FRT-15L3 legal in my state?
Firearm laws vary drastically by state and locality. The FRT-15L3 is a component that modifies the firing cycle of a semi-automatic firearm. It is the purchaser’s sole responsibility to research and comply with all federal, state, and local laws regarding firearm modifications before purchase and installation. We do not provide legal advice.
What Glock models is this compatible with?
The selector is designed for Glock Gen 3, Gen 4, and Gen 5 models that use the standard frame-mounted safety lever. This includes common models like the G17, G19, G22, G23, etc. Always double-check your specific model’s compatibility. It will not fit models with different safety systems (e.g., Gen 1/2, or models like the G42/43).
How difficult is the installation?
Installation requires a detail strip of the Glock frame to access the trigger mechanism housing. You will need a punch to drive out the pins holding the factory safety lever. If you are comfortable performing a full frame disassembly and reassembly, it is a straightforward swap. If not, have a qualified gunsmith perform the installation.
Does this work with aftermarket triggers or connectors?
It is designed to work with OEM-style trigger bars and connectors. Compatibility with heavily modified or non-standard trigger systems is not guaranteed. For reliable function, we recommend testing with an OEM or known-compatible trigger setup first.
What is the difference between FRT and a binary trigger?
A binary trigger fires one round when the trigger is pulled and a second round when the trigger is released. An FRT (Forced Reset Trigger) uses a mechanical system to push the trigger forward immediately after the sear releases, allowing for a very rapid subsequent pull as long as the shooter maintains forward finger pressure. The firing cycle is different.
Will this part wear out my Glock faster?
Any modification that increases the rate of fire will increase wear on components. The FRT-15L3 is built from hardened steel to endure this, but you may see accelerated wear on other parts like the slide, recoil spring assembly, and possibly the frame rails over extensive use. Regular inspection and maintenance are crucial.
