Understanding the Johnny Glock Advantage
Before diving into potential issues, it’s crucial to appreciate the appeal of Johnny Glock triggers. These triggers often incorporate modifications to various internal components, like the trigger bar, firing pin assembly, and connector, to deliver a smoother, lighter pull weight. The shorter reset allows for faster follow-up shots, and the improved feel can enhance overall shooting accuracy. By understanding the intended benefits, users can better evaluate and address any problems they may experience.
Light Primer Strikes: A Frustrating Occurrence
One of the most frustrating issues that can plague a Johnny Glock trigger setup is light primer strikes (LPS). This occurs when the firing pin doesn’t deliver enough force to reliably ignite the primer of the cartridge. The result is a “click” instead of a “bang,” and a potentially unreliable firearm. Several factors can contribute to this problem when using a Johnny Glock trigger.
Reduced Firing Pin Spring Weight
One of the most common culprits is a reduced firing pin spring weight. Johnny Glock often provides lighter firing pin springs as part of their trigger kits, designed to reduce the trigger pull weight. While this can improve the trigger feel, a spring that’s too light may not generate sufficient momentum to reliably ignite all types of ammunition, especially those with harder primers.
Firing Pin Issues
Another area to examine is the firing pin itself. Issues could include improper polishing, which can hinder smooth movement within the firing pin channel. Wear on the firing pin, especially near the tip, can also diminish its ability to deliver consistent impact.
Incorrect Seating
Incorrect seating of the firing pin or firing pin spring is a frequently overlooked cause. If the firing pin isn’t correctly positioned within its channel or the spring isn’t seated properly, the system won’t function as intended. Always disassemble and reassemble the firing pin assembly with meticulous care.
Firing Pin Channel Problems
The firing pin channel itself may present problems. Debris, such as carbon buildup or small particles, can restrict the firing pin’s movement. Damage within the channel, like scratches or burrs, can also impede performance. A thorough cleaning and inspection of the firing pin channel are essential.
Addressing the Light Primer Strike
When experiencing light primer strikes with a Johnny Glock trigger, a systematic approach is critical. Start by verifying ammunition compatibility. Some ammunition brands or types may have harder primers than others, making them more prone to LPS. Try different brands of ammunition to determine if the issue persists across the board.
Checking Protrusion
Carefully check for proper firing pin protrusion. The firing pin should extend a certain distance beyond the breech face when the trigger is pulled. If the protrusion is insufficient, it won’t reliably ignite the primer.
Inspecting and Replacing Springs
Inspect and replace the firing pin spring. Consider testing different spring weights, starting with the factory spring, and gradually experimenting with lighter options until you find a reliable solution.
Cleaning the Channel
Thoroughly examine the firing pin channel for debris, and clean it meticulously. A clean channel allows for unimpeded firing pin movement.
Considering a Heavier Spring
If the problem persists, consider using a heavier firing pin spring. While this might slightly increase the trigger pull weight, it can often solve the LPS problem by providing more striking force.
Failure to Reset: A Disabling Defect
Failure to reset (FTR) is another significant problem. When the trigger doesn’t reset after firing, the firearm becomes inoperable until the slide is manually cycled. This malfunction can severely compromise the reliability of the firearm and poses a significant safety concern.
Connector Issues
Various components in a Johnny Glock trigger setup can contribute to FTR. The connector is often a critical component, responsible for disengaging the trigger bar to allow the trigger to reset. An incorrectly angled connector, or one with excessive wear, can fail to properly perform this function.
Over-Travel Stop Problems
An over-travel stop, if present, may need adjustment. If the over-travel stop is set too aggressively, it can restrict the trigger’s movement, preventing the trigger bar from engaging the connector and resetting.
Trigger Bar Interference
Trigger bar interference can also prevent the reset. If the trigger bar is rubbing against the frame or other components, its movement might be hindered, making a full reset impossible.
Trigger Spring Issues
A weak or damaged trigger spring, responsible for returning the trigger to its forward position, can also cause FTR. A fatigued or broken spring won’t provide the necessary force for a complete reset.
Overcoming the Failure to Reset
Address FTR issues by starting with an examination of the connector. Check the connector for proper alignment and any signs of wear. Consider replacing the connector, or experimenting with connectors of different angles.
Adjusting the Over-Travel Stop
Adjust or remove the over-travel stop, if present. Ensure there’s adequate clearance for the trigger to move freely.
Checking Trigger Bar Movement
Verify that the trigger bar moves freely and is not obstructed by any other parts. Check for contact with the frame or other components. Ensure that the trigger bar is seated correctly and not catching on anything.
Replacing the Trigger Spring
Replace the trigger spring to ensure it’s delivering the necessary force for reset.
Lubricating the Mechanism
Lubricate the trigger mechanism to reduce friction and improve smooth operation. Use a high-quality gun lubricant.
Trigger Feel: Striving for the Ideal Pull
Beyond functional problems, the “feel” of the trigger can also be a source of frustration. Issues include a gritty pull, a mushy feel, excessive pre-travel, or over-travel. These issues can detract from the shooting experience and negatively affect accuracy.
Polishing and Finishing
The quality of polishing or finishing of the trigger components can affect the pull. Rough surfaces on the trigger bar, connector, or firing pin assembly can create friction, leading to a gritty feel.
Spring Selection
Incorrect spring selection can also influence the trigger feel. Springs that are too heavy can make the pull feel stiff, while springs that are too light may lead to a mushy feel.
Connector Issues
Connector incompatibility or wear can also be the culprit. A connector that doesn’t interface properly with the trigger bar can make the pull feel inconsistent.
Trigger Bar Problems
Issues with the trigger bar, such as a bent or damaged bar, can result in an erratic trigger pull.
Refining the Trigger Feel
Disassemble the trigger assembly and thoroughly clean and lubricate the components. Polishing any rough surfaces on the trigger, trigger bar, connector, and firing pin assembly can help reduce friction.
Experimenting with Connectors
Experiment with different connector types and angles to find the combination that yields the best pull.
Spring Adjustments
Consider replacing springs with different weights to fine-tune the trigger feel. A lighter spring might result in a smoother pull, while a heavier spring might feel more crisp.
Checking for Obstructions
Check for burrs or obstructions within the trigger channel. Any impediments can hinder the trigger’s movement and negatively affect the feel.
