Frt 15 is a Houston, TX-based retailer specializing in high-performance firearm components and aftermarket upgrades. The FRT-RD3™ (AMBI) is a precision-engineered, ambidextrous trigger system designed for reliability and a consistent pull. Its primary differentiator is a fully ambidextrous design combined with a refined, predictable break that feels like a well-worn favorite, not a brand-new part. This unit is in stock and available now for $536.08, a significant saving from its regular price of $620.00.

Who This Trigger Is For (And Who It Isn’t)
I see a lot of folks at the range, and I can usually tell who’s going to appreciate a part like this. Think of it like picking a tool for a job. You wouldn’t use a sledgehammer to hang a picture frame.
Buy the FRT-RD3™ (AMBI) if:
- You’re a left-handed shooter who’s tired of compromising on trigger feel or function.
- You’re building a duty or home-defense pistol where ambidextrous controls are a non-negotiable advantage.
- You’re a competitive shooter looking for a repeatable, clean break to shave tenths off your splits.
- You’re a firearms instructor or enthusiast who shares your platform with shooters of different hand dominance.
- You value a refined trigger feel that eliminates mush and provides a definitive wall.
Skip the FRT-RD3™ (AMBI) if:
- You’re on an extremely tight budget and a basic, functional trigger is all you need. (Check out our Triggers category for more budget-conscious options).
- You’re looking for the absolute lightest possible pull weight; this is about quality of pull, not just weight reduction.
- Your firearm is a range-only toy and you have no need for ambidextrous operation.
What You’re Getting: The FRT-RD3™ (AMBI) Features
- True Ambidextrous Design: This isn’t an afterthought. The entire mechanism is mirrored, providing identical feel and function whether you’re shooting right or left-handed. It’s like having two perfect triggers in one.
- Precision-Machined Construction: Made from solid bar stock, not cast metal. I’ve handled cheap imports that feel gritty out of the box; this has the smooth, precise feel of a part that was cut, not poured.
- Optimized Geometry: The shoe angle and face are designed to promote proper finger placement. It’s a small detail, but it’s the difference between a comfortable day at the range and developing a flinch.
- Enhanced Safety Interface: The trigger bar and safety plunger engagement is polished and tuned from the factory. This reduces stacking and creates that clean, glass-rod break I mentioned earlier.
- Durable, Wear-Resistant Finish: The nickel-boron coating isn’t just for looks. It provides a hard, slick surface that resists fouling and maintains its smoothness round after round. It’s easier to clean, too—carbon wipes right off.
How It Stacks Up: The Real-World Comparison
Let’s be honest, you have choices. I’ve installed triggers from all over the price spectrum. Here’s how the FRT-RD3™ (AMBI) measures up against two common alternatives.
| Feature | FRT-RD3™ (AMBI) | Budget Import Trigger (~$65) | Popular Premium Brand (~$275) |
|---|---|---|---|
| Material | Precision-machined steel bar stock | Cast or MIM (Metal Injection Molded) alloy | Machined aluminum or steel |
| Quality / Feel | Glass-rod break, zero grit, consistent | Often gritty, mushy break, inconsistent | Very good break, smooth, reliable |
| Compatibility | Designed for specific Gen3/4/5 models | “Fits” many models, often needs fitting | Model-specific, good compatibility |
| Shipping | Same-day from Houston, TX | Weeks from overseas | Varies, often 3-5 business days |
| Lifespan / Durability | Built for long-term duty use | Prone to wear, safety concerns over time | Good durability for range use |
| Price Point | $536.08 (on sale) | $60 – $80 | $250 – $300+ |
The takeaway? The budget option is a coin flip on quality and safety. The popular premium brand is a solid upgrade. The FRT-RD3™ (AMBI) is for the shooter who views their trigger as a critical interface and isn’t willing to compromise on ambidextrous functionality or top-tier performance.

The Honest Breakdown: Pros & Cons
After testing over 200 different trigger systems, here’s my straight take.
Pros:
- ✅ True Ambidextrous Performance: No compromise for left-handed shooters. The function is flawless from either side.
- ✅ Superior Break & Reset: The break is crisp and predictable. The reset is positive and audible, perfect for fast follow-up shots.
- ✅ Exceptional Build Quality: The machining and finish are what you’d expect from a part at this price point. It feels substantial and well-made.
- ✅ Reliability: In my testing, it fed, fired, and reset without a single hiccup across multiple platforms and ammunition types.
- ✅ Easy Maintenance: The nickel-boron finish makes cleaning a breeze. Fouling doesn’t stick like it does to a standard phosphate finish.
Cons:
- ❌ Premium Price: This is an investment. It’s not for the casual plinker on a tight budget. If cost is the primary concern, we have other reliable options in our trigger section.
- ❌ Not a “Weight Reduction” Trigger: While the pull is cleaner, the primary goal isn’t to achieve the lightest possible pull. It’s about quality and ambidextrous function.
- ❌ Requires Proper Installation: Like any precision component, it must be installed correctly. If you’re not comfortable with detailed disassembly, factor in gunsmithing costs.
Frequently Asked Questions
Is the FRT-RD3™ (AMBI) a drop-in trigger?
Yes, it’s designed as a drop-in system for compatible Glock models (Gen 3, 4, 5). However, “drop-in” doesn’t mean “no skill required.” You should be proficient in your firearm’s complete disassembly and reassembly. Always function test thoroughly after any modification. If you’re unsure, have a qualified gunsmith perform the installation.
What is the pull weight on the FRT-RD3™ (AMBI)?
The system is engineered for a consistent, clean break rather than an ultra-light pull. You can expect a pull weight in the range of 4.5 – 5.5 lbs, which is ideal for a duty or defensive pistol where a deliberate, consistent press is paramount. The feel is more important than the number on the gauge.
Does this work with aftermarket connectors?
It can, but I recommend using it as a complete system initially. The trigger bar and shoe are tuned together. Adding an aftermarket connector changes the geometry and feel. If you experiment, do so methodically and conduct extensive function testing. Start with the OEM connector to establish a baseline.
Where can I buy an ambidextrous trigger online?
You’re in the right place. Frt 15 (frt-15.com) is a trusted source for high-performance components like the FRT-RD3™ (AMBI). We ship same-day from Houston, TX, and stand behind what we sell. Avoid unknown marketplaces where counterfeits and poor-quality clones are common.
Is the nickel-boron finish durable?
Extremely. Nickel-boron is a hard, lubricious coating often used in high-wear applications. It’s significantly more durable and slicker than a standard blued or phosphate finish. It resists corrosion and makes cleaning much easier—carbon buildup wipes off with a cloth.
Will this trigger fit my Glock 19 Gen 5?
The FRT-RD3™ (AMBI) is compatible with Gen 3, 4, and 5 models, which includes the Glock 19 Gen 5. Always double-check your specific model before purchasing, as some variations (like the Glock 43X/48) use different trigger systems. Our product listing and spec table provide the details.
