GlockWORX Fulcrum Trigger and Parts – Test and Evaluation

glock 19 modified trigger

GLOCK 19 with GlockWORX Fulcrum trigger and magazine release button.

Following SHOT Show 2011, I spoke with Ray Wong at GlockWORX, a division of ZEV Technologies. I was primarily looking at a trigger system for the GLOCK 29SF, maybe for the 19 as well, to improve the break.

The 3rd generation GLOCK 19 and 29SF are OEM, with the exception of Ghost Recon connectors. If I felt like grinding away at a Ghost Rocket connector, I may have appreciated the modification more on the 29SF.

Nonetheless, I was quite happy with the set-up on the 19. The 29SF, could use some improvement. The trigger on a 29SF didn’t break as clean as the 19 did and perceived the pre-travel longer than desired. I couldn’t justify spending $70.00 on the trigger set, so Ray helped me out and sent me their Fulcrum Ultimate Trigger Kits to play with for the 19 and 29SF.

Some folks use their GLOCK for competitions, whereas others strictly use it for self-defense. The kit is an assortment of parts, so there’s plenty of opportunity to configure your GLOCK according to your needs.

• 2/56 Set screws in front and back of the trigger to adjust over travel and pre travel.
• V3 Race Connector
• ZT Skeletonized Striker
• ZT Reduced Power Striker Spring
• ZT Standard Power Striker Spring
• ZT Trigger Spring
• ZT Titanium Firing Pin Safety
• ZT Firing Pin Safety Spring
• Ejector housing
• Instructions and two Allen wrenches included

I primarily used the 19 as the test model for the Fulcrum. OEM trigger pull with a buff and polish, and Ghost Recon connector is a satisfactory 4lbs and 7oz. Many rounds have been through this GLOCK, which might explain the .5lbs difference from typical factory new models.

The Fulcrum Trigger was simple to install. Tuning the trigger’s pre-travel and travel, which are adjusted using the 2/56 screws in the front and back, is time consuming, however.  For this initial test, I didn’t make any adjustments. With the trigger unit alone, the pull measured 3.5lbs. The break was perceived as light, but clean.

As instructed, I performed safety checks to ensure the trigger was functioning properly. I initially believed it to function just fine; however, after performing many dry fires and malfunction drills, I discovered that the striker would intermittently fall if I reset the trigger. Eventually, I discovered that I was able to repeat the failure almost all the time if I pulled the slide up from the frame when I reset the trigger.

I contacted Ray for input. My initial thoughts was a bad factory safety pin, but he noted that the connector is likely bent out too far – could have been bent during packaging, shipping, or installation. I verified this by installing the factory connector. He sent me two replacement race connectors, one for each kit I received, to rectify the issue.

Issue corrected and confirmed, I carried the 19 on a regular basis and used it for Todd Green’s class. After shooting 1200 rounds or so with the new trigger, I experienced no trouble with the kit.

Using the additional components the kit came with, I continued to measure the trigger pull and noted any perceived differences.

Adding the titanium firing pin safety didn’t alter the trigger weight, but I did perceive a subjective difference with the break. With the light striker installed, it wasn’t as audible when it fell. I may have perceived less vibration, but the difference was so minor, I’m inclined to believe I willed myself out of expectation. Trigger pull remained at 3lbs. until I installed the 2lbs. striker spring, which yielded a 2.5lbs. pull without any additional work. Additional work and experimentation reportedly yields a safe trigger pull as low as 1.5lbs.

Adjusting pre-travel and over-travel, as mentioned earlier, will likely be more time consuming than difficult. Adjustments are made through trial and error by tightening or loosening the set screws when the trigger is not in the frame, then installing it back for testing. Count on repeating this process. One must be mindful to not decrease the pre-travel to the point at which the trigger safety does not engage, or not reset with the proper gap between the Fulcrum Trigger safety and frame.

I experimented with the trigger quite a bit more with the 29SF. Factory setting allowed appropriate clearance, but I perceived no pre-travel. After punching the GLOCK pins off the frame several times, and trial and error, I found a sweet spot for the 10mm.  Note to make adjustments one turn at a time – it’s a lot easier to keep track. Think of it as a titration experiment.  Also note that the SF models use a different ejector housing than the regular original models. Beyond that, the factory ejector housing does not appear to be different than the one provided with this kit.

Their magazine release buttons are well made and would prove appropriate for competition. Their recoil springs are available in various weights, offered in round or ISMI wires and their slide lock lever can pick up the slack in the slide.  The blue, red, and green round springs provided to me appear more appropriate for lighter loads.  For my purpose, I didn’t favor them.  I may have preferred the ISMI springs instead.

After all that fiddling, I was pretty happy with the outcome for the two GLOCK models using an assortment of GlockWORX parts. Having so many options made available is pretty flippin’ cool — for competition or self-defense. GlockWORX offers a huge variety of weighted recoil springs, spring guides, magazine eject buttons, and other assorted GLOCK parts, it would be inconvenient to look elsewhere in one stop.

Which parts are right for you?

I was fortunate to try out the Fulcrum Trigger and other GlockWORX parts on my GLOCKs to experience for myself what my GLOCK can be.  Through my experience, I was pleased how the Fulcrim Trigger improved “finger ergonomics,” and cleaner function without sacrificing safety.  I believe it’s noteworthy that I carried the modified 19 using the Archangel AIWB holster after initial testing.  AIWB = you die if you fuck up.

Granted, I wouldn’t add every single product GlockWORX creates.  For my purpose, that would be cost prohibitive and likely unnecessary.  However, if I were to pull out my credit card right now to spruce up my GLOCK 19 and 29SF for self-defense, I would purchase the following parts:

V3 Race Connector

CCW Magazine Release

Can you tell I take the minimalist’s approach?

The Fulcrum Trigger is a solution for those who are willing to experiment and modify their GLOCKs with a honest understanding what their goals are – whether if that may involve plinking, competition, or self-defense.  As great as GlockWORX products are, I would hesitate to recommend any DIY trigger modification to a new shooter or to the mechanically challenged.  Don’t misunderstand me — I absolutely believe GlockWORX’s products are safe, but human error is a bitch.  If you’re not comfortable with DIY installation, GlockWORX offers a comprehensive list of gunsmithing services.

Bottom line:  GlockWORX provides an excellent assortment of products and their customer service is top-notch.  GlockWORX stand behind their products and will kindly assist you through any project you might have.

Just bear in mind a GLOCK is still a GLOCK.

    Was there a significant difference in ease of use with the new mag release? The greatest difficulty the wife and I had at our recent LMS pistol clinic was with the mag release buttons on our new-in-box Glock 19s. They got easier to use as the day wore on, to the point where I’m wondering if changing them out is really necessary.

      I didn’t get to evaluate the GlockWORX CCW magazine button specifically, but I am aware that it requires less pressure to activate. Most people won’t need it, but I would like one on the GLOCK 29SF seeing as how the grip is slightly wider.

      I don’t think the GLOCk 19 needs one.
