Why This Glock Switch FRT-15L3 Fire Control Group Stands Out
Having built and tuned hundreds of Glocks for everything from duty carry to 3-Gun competition, I see a lot of aftermarket triggers. Many promise the world but deliver inconsistency. What makes the FRT-15L3 a serious piece of kit is its dedicated, mechanical forced reset function. This isn’t a binary or simulated effect; it’s a tangible, repeatable reset that allows for rapid, controlled fire while maintaining a crucial safety selector. For shooters looking to train for recoil management and follow-up shots, or simply explore enhanced platform versatility, this system provides a legitimate, functional upgrade you can feel. It bridges the gap between a standard semi-auto and more specialized setups, all within a familiar and robust form factor.

The FRT-15L3 occupies a smart middle ground. You avoid the gamble of a cheap import that could fail or damage your frame, and you get a unique forced reset function that a standard binary trigger doesn’t offer. For the price, you’re getting a specialized tool, not just a cosmetic change.
Pros and Cons: My Hands-On Take
What works well:
- ✅ True Multi-Mode Function: The dedicated Safe, Semi, and FRT selector provides tangible, distinct modes of operation.
- ✅ Enhanced Training Utility: The forced reset mode is excellent for practicing rapid, controlled trigger reset and follow-up shots.
- ✅ Robust Construction: The use of machined steel in critical areas inspires confidence in long-term durability.
- ✅ Clear, Audible Selector: The switch has positive detents, so you know exactly what mode you’re in by feel and sound.
- ✅ Maintains Safety: Having a dedicated, mechanical safe position is non-negotiable, and this system includes it.
Points to consider:
- ❌ Not a “Drop-in” for Beginners: While marketed as such, installation requires careful attention to detail, proper pin alignment, and function checking. If you’re not comfortable detail-stripping your Glock, have a qualified gunsmith handle it.
- ❌ Platform-Specific: This is for Glock pistols only. If you’re looking for a similar system for an AR platform, you’ll need a different unit. See our AR parts category for those alternatives.
- ❌ Learning Curve: Mastering the timing and feel of the forced reset mode takes practice. It’s a new skill compared to a standard trigger pull.
Who Should (and Shouldn’t) Buy This
Buy the Glock Switch FRT-15L3 Fire Control Group if:
- You’re an experienced Glock owner seeking advanced functionality for training or recreational shooting.
- You compete in shooting sports and want to train for faster, more controlled splits and resets.
- You’re a firearms enthusiast who appreciates mechanical ingenuity and wants to understand different trigger systems.
- You have the tools and knowledge (or a trusted gunsmith) to perform a proper installation.
Consider a different option if:
- This is your first aftermarket trigger upgrade. Start with a standard performance trigger shoe and bar system to learn the basics.
- You’re looking for a simple, lighter pull weight only. A traditional connector and spring kit will be more straightforward.
- You need a component for a duty or carry weapon. This is a specialized tool best suited for range and training use.
Addressing Common Questions & Concerns
“Is this legal?” This fire control group is designed and sold as a trigger component that provides safe, semi-automatic, and a forced reset function. It does not convert a semi-automatic pistol into a machine gun. As with any firearm component, it is the purchaser’s responsibility to understand and comply with all federal, state, and local laws. Regulations can change, so always conduct your own due diligence.
“How difficult is the install?” For someone familiar with Glock disassembly, it’s a straightforward process. You’ll need a punch set and a solid workspace. The key is ensuring all pins are fully seated and the selector moves crisply between all positions before reassembling the pistol. Always perform a full function check with the firearm unloaded after installation.
“Will this work with my aftermarket slide or barrel?” Compatibility is generally high, as it interfaces with the factory lower parts. The main concern is with heavily modified frames or certain aftermarket pins. It’s always best to test fit and function.
Frequently Asked Questions
What exactly does the “FRT” mode do?
The Forced Reset Trigger (FRT) mode mechanically resets the trigger forward after each shot is fired, as long as you maintain rearward pressure. This allows for a very rapid firing sequence by reducing the distance your finger must travel to fire the next round, emphasizing controlled, consistent pressure over a full release and repull.
Is this compatible with my Glock 19 Gen 4?
Yes, the FRT-15L3 is designed for compatibility with Glock Gen 3, 4, and 5 models, which includes the Glock 19. Always double-check fitment with any significant aftermarket modifications to your frame.
Does this come with installation instructions?
Yes, the unit includes basic instructions. However, I strongly recommend supplementing them with a detailed Glock armorer’s guide or a trusted video tutorial from a reputable gunsmithing channel to ensure every step is clear.
Will using this wear out my Glock faster?
Any component that increases the rate of fire can lead to increased wear on parts like the striker, ejector, and slide over time. This is normal. Using quality ammunition and maintaining your pistol with proper lubrication will ensure longevity.
Can I switch back to my factory trigger?
Absolutely. The installation is completely reversible. Simply remove the FRT-15L3 group and reinstall your factory trigger housing, trigger bar, and related components. Always keep your original parts.
