Understanding the Foundation: The Anatomy of the WMP Trigger System
Before embarking on any upgrade path, understanding the existing system is crucial. The Walther WMP, being a striker-fired pistol, employs a trigger mechanism that efficiently translates the shooter’s input into the discharge of a round.
The core components of the WMP trigger system include the trigger itself, a trigger bar, a sear, a striker, and various springs. The trigger, when pulled, actuates the trigger bar, which in turn interacts with the sear. The sear holds the striker in a cocked position. Upon full trigger pull, the trigger bar releases the sear, allowing the striker to move forward and strike the primer of the cartridge, initiating the firing sequence.
The factory trigger pull weight on the WMP is designed to be safe and reliable. However, this often translates into a heavier pull weight and a longer reset distance than some shooters prefer. This can lead to a less crisp break, making precise shot placement more challenging, especially during rapid-fire scenarios. The reset, the distance the trigger must travel forward before it can engage the sear again, also affects how quickly subsequent shots can be taken. A long reset can hinder the shooter’s ability to maintain a consistent cadence.
Potential areas for improvement with a Walther WMP trigger upgrade include: decreasing the trigger pull weight, which makes the trigger easier to actuate; achieving a crisper trigger break, ensuring a more predictable and clean release of the striker; reducing the reset distance, enabling faster follow-up shots; and minimizing over-travel, the distance the trigger moves after the shot breaks. These enhancements contribute to greater control and accuracy, transforming the shooting experience.
Exploring Your Options: A Range of Trigger Upgrade Pathways
Fortunately, for those seeking to optimize their WMP’s trigger, a variety of upgrade options are available. The choices range from simple component swaps to more comprehensive upgrades.
Aftermarket trigger kits offer a convenient, all-in-one solution. Several companies specialize in crafting trigger kits specifically designed for the Walther WMP. These kits often include a replacement trigger, springs, and sometimes other components like trigger bars or sear springs. Popular brands that create kits for the WMP include, for example, Apex Tactical, and others that specialize in parts and upgrades for Walther pistols. These kits aim to provide a significant improvement in trigger feel and performance with a single purchase.
The features of these kits vary. Some focus on reducing trigger pull weight, while others prioritize a crisper break and a shorter reset. The specific components included in each kit also differ. Some might only provide a trigger return spring and a striker spring, while others may offer a complete replacement of internal parts, including the trigger itself. Installation is usually straightforward, but always consult the specific instructions that come with the kit. These instructions often include diagrams and helpful hints to ensure a smooth installation process.
Beyond complete kits, another approach is to upgrade individual components. This allows for a more tailored approach and potentially lower costs.
Trigger Springs:
Trigger springs, especially the trigger return spring and the striker spring, are often the first point of modification. Replacing the factory springs with lighter-weight alternatives can contribute to a lighter trigger pull weight and a more responsive trigger action. However, it is important to source quality springs from reputable manufacturers to maintain reliability and ensure the safe function of the firearm.
Sear and Striker Polishing:
Another popular area for improvement is to polish internal surfaces. Polishing the sear and the striker can significantly affect the trigger feel. Smoothing these surfaces can reduce friction and create a crisper, cleaner break. This process involves carefully using polishing compounds and tools to remove microscopic imperfections from the mating surfaces of the sear and the striker. Careful attention should be paid during the process, as too much alteration or improper polishing could potentially compromise the firearm’s function. Caution should be exercised, and if you’re not comfortable doing this yourself, consider seeking assistance from a qualified gunsmith.
Trigger Shoes and Accessories:
Furthermore, the use of a trigger shoe can change the feel of the trigger. Trigger shoes come in various shapes and sizes. Some shooters may prefer a flat trigger shoe, which provides a consistent surface for their finger and promotes a more linear trigger pull. Others might prefer a curved trigger shoe for better grip, and the improved feel. The choice of a flat or curved trigger shoe is often a matter of personal preference, and different brands offer various styles to suit individual hand sizes and shooting styles.
A Safe and Secure Process: Installation and Safety Guidelines
Before installing any trigger upgrade, remember to prioritize safety and follow all relevant instructions.
When working on any firearm, the first and most critical step is to ensure that it is unloaded. Always remove the magazine and visually inspect the chamber to confirm that no round is present. Consider storing the firearm’s ammunition separately while you work on the pistol.
Find a clean, well-lit workspace, ideally free from distractions. Gather all the necessary tools, including the tools that come with the upgrade kit, and any tools suggested by the manufacturers instructions or needed for removal of your current trigger.
Carefully follow the installation instructions provided with the trigger upgrade kit. Most kits include detailed diagrams and step-by-step instructions. If you are uncomfortable with any part of the installation process, or if the instructions are unclear, consult with a qualified gunsmith. Never force any components during the installation process.
After installing the trigger upgrade, thoroughly test the function of the trigger. Verify that the trigger operates smoothly, that the striker releases the round when the trigger is pulled, and that the safety mechanisms function correctly. If you encounter any issues, do not use the firearm until they are resolved.
Finally, if you are not experienced with firearm maintenance or uncomfortable performing these upgrades, it is always best to seek professional assistance from a qualified gunsmith.
Assessing the Results: Measuring the Impact of Your Upgrades
Once you’ve completed the Walther WMP trigger upgrade, you’ll want to assess the results. A methodical approach will help you determine the effectiveness of the changes you’ve made.
Before you begin, take the time to measure the trigger pull weight. You can use a trigger pull gauge, available at most gun stores. Measure the trigger pull weight before the upgrade, and compare it to the measurement after the upgrade. The difference in pull weight will be the most obvious change and should be the most readily apparent measure of improvement.
Evaluate the crispness of the trigger break. This is a more subjective assessment. Carefully dry-fire the pistol, paying attention to the feel of the trigger as it breaks. A crisper break provides a more predictable and controlled release of the striker. Compare the feel before and after the upgrade.
Test the reset of the trigger. How far does the trigger have to move forward before it resets and can fire again? A shorter reset can lead to faster follow-up shots.
The best way to assess your upgrades is to go out and shoot. Bring a target and some ammunition, and test your pistol’s performance. Do you find it easier to hit your target? Are your groupings more consistent? Are your split times quicker? These are some of the measurements that will reveal how the new trigger upgrade is working for you.
A Path to Excellence: Final Thoughts and Recommendations
Upgrading the trigger on your Walther WMP can be a transformative experience, resulting in improved accuracy, enhanced control, and a more enjoyable shooting session. By carefully selecting the right components and following the proper installation procedures, you can optimize your pistol’s performance to meet your unique needs and preferences.
The best trigger upgrade for your Walther WMP will ultimately depend on your individual shooting style and the goals you have in mind. If you are primarily concerned with reducing trigger pull weight and achieving a crisper break, then a complete aftermarket trigger kit may be the most effective solution. If you’re seeking a more tailored approach, or you want to try out several changes, upgrading individual components may be better, as you can choose which parts to replace.
Ultimately, the journey of enhancing your Walther WMP’s trigger is a personal one. Experiment with different options, find what works best for you, and enjoy the journey of transforming your pistol into a finely tuned instrument of precision.
Remember that safety should always be your top priority when working with firearms. If you have any doubts or concerns, consult with a qualified gunsmith.
