This article delves into the common Kimber Evo SP problems experienced by owners, offering insights into potential causes and providing practical troubleshooting steps to keep your pistol running smoothly.
From the outset, it’s crucial to acknowledge that owning and operating any firearm comes with a responsibility. This article provides information for troubleshooting purposes only and should not be considered a substitute for proper firearms training or professional gunsmithing. Always prioritize safety and adhere to all applicable laws and regulations.
Understanding the Kimber Evo SP
Before diving into the problems, it’s helpful to understand the core characteristics of the Kimber Evo SP. This pistol typically chambered in 9mm, stands out for its compact nature. This design makes it exceptionally well-suited for concealed carry. Its frame is often crafted from aluminum alloy, contributing to its reduced weight, and the slide often features a unique and attractive design. The trigger is a key element and a feature that many owners appreciate. While the features are usually well-regarded, inherent in any mechanically complex design there may be issues.
Failure to Feed Challenges
One of the most frequently reported Kimber Evo SP problems revolves around the issue of failure to feed (FTF). This occurs when the pistol fails to chamber a round properly, preventing it from firing. Understanding the potential causes and employing preventative measures can resolve this issue.
Magazine Issues
A common culprit in FTF scenarios is related to the magazines. Over time, magazine springs can weaken, failing to adequately push rounds upward into the chamber. The magazine lips, which hold the rounds in place, can also become damaged or spread, making it difficult for the rounds to align correctly. Inspect your magazines regularly for any signs of wear, damage, or deformation. Replacing the magazine spring is often a simple and effective solution. For those using the original factory magazine, cleaning and properly maintaining them are also key to longevity and function.
Feed Ramp Problems
Another critical factor is the feed ramp. This angled surface within the frame guides the bullet into the chamber. A rough or poorly polished feed ramp can cause friction and prevent the round from sliding smoothly. While it’s generally advisable to avoid making significant modifications to your firearm, some gun owners opt to polish the feed ramp using appropriate tools and techniques. A professional gunsmith is recommended for doing this work to ensure it’s done properly. Avoid any aggressive filing or alterations that could negatively impact the firearm’s reliability.
Ammunition Compatibility
The type of ammunition can also play a role. The bullet shape, overall length, and even the bullet’s coating can influence how well it feeds. Some ammunition brands or bullet profiles may not function reliably in the Evo SP due to their specific dimensions or characteristics. Experiment with different ammunition types to find what performs best in your pistol. Consider the reputation of the ammunition manufacturer and any specific recommendations from Kimber regarding compatible ammunition.
Lubrication
Finally, insufficient lubrication can contribute to FTF. The slide needs to move freely and the rounds must slide. Ensure that the rails, the feed ramp, and other key areas are properly lubricated. Over-lubrication, while less likely to cause immediate issues, can attract debris.
Extraction Frustrations
Another significant area of potential Kimber Evo SP problems revolves around failures to extract (FTE). This happens when the spent casing fails to eject from the chamber, which jams the firearm and prevents it from firing the next round.
Extractor Issues
The extractor is the small, spring-loaded claw that grips the rim of the spent casing to pull it out of the chamber. If the extractor is worn, damaged, or has insufficient tension, it may not be able to hold the casing firmly enough, leading to FTE issues. Inspect the extractor regularly for wear or damage and clean it thoroughly. If the extractor doesn’t seem to be able to do its job, you may need to replace it or seek professional assistance.
Chamber Cleanliness
The chamber itself must also be clean. Debris, powder residue, or other buildup can interfere with the extraction process. Clean the chamber meticulously after each shooting session.
Recoil Spring Fatigue
The recoil spring, which absorbs the energy from the slide’s rearward movement, can also contribute to FTE. If the recoil spring is weak or has lost its spring strength, the slide may not cycle completely, potentially resulting in FTE. Replacing the recoil spring according to the manufacturer’s recommendations is an easy fix.
Ammunition Considerations
The type of ammunition is important here too. Some ammunition may have lower pressure and not generate enough force for the slide to cycle effectively.
Slide Lock Blues
Another area of concern in Kimber Evo SP problems lies in the slide not locking back on an empty magazine. This can hinder the reloading process and detract from the pistol’s usability.
Magazine Follower Problems
The primary component responsible for engaging the slide stop lever is the magazine follower. As the last round is fired, the follower pushes the slide stop lever up, locking the slide open. If the magazine follower is damaged, worn, or otherwise unable to reach the lever, the slide will not lock back. Inspect your magazines carefully, including the magazine follower, to make sure they are in good condition. Magazine replacement is a common solution to this.
Slide Stop Lever Inspection
The slide stop lever itself may be defective, damaged, or worn over time. It can also be affected by build-up of residue. The mechanism should be clean, undamaged, and move freely. Consider cleaning or replacing the slide stop lever if there are visible problems.
Magazine Spring Influence
The magazine spring can play a role here too. A weak magazine spring may not provide enough force to push the follower up into contact with the slide stop lever. Magazine spring replacement may be needed.
Light Primer Strike Frustrations
Light primer strikes (LPS) are another type of Kimber Evo SP problems that can cause frustration and reliability issues. When a light primer strike occurs, the firing pin doesn’t strike the primer with enough force to ignite the primer compound, and the round fails to fire.
Firing Pin Spring Issues
The firing pin spring is critical for providing the necessary force. If the firing pin spring is weak or damaged, it may not generate sufficient force to reliably ignite the primer. If the spring has broken, replace the spring.
Firing Pin Channel Cleaning
The firing pin channel can also become clogged with debris or residue, which impedes the firing pin’s movement. Thoroughly clean the firing pin channel to ensure the firing pin can move freely.
Hammer/Mainspring Considerations
Additionally, the hammer or the mainspring, which provides the initial force for the firing pin, can play a role. If these components are compromised, it can reduce the force delivered to the firing pin.
Trigger Troubles
The trigger mechanism, a critical part of any firearm, is subject to its own set of potential issues.
Debris Buildup
Debris or gunk can get trapped in the trigger mechanism, interfering with smooth operation. Disassemble the trigger mechanism carefully and meticulously, and then clean any grime or fouling.
Part Degradation
Damage to trigger parts, like the sear or trigger bar, can cause trigger malfunctions. Inspect these parts for any signs of wear, damage, or deformation.
Troubleshooting and Maintenance Best Practices
Consistent maintenance, troubleshooting, and ammunition compatibility are vital to reliability.
Cleaning and Lubrication Routine
Regular cleaning after each shooting session is essential for removing carbon buildup, debris, and other contaminants that can affect function. Use a quality gun cleaning solvent and follow the manufacturer’s instructions. Pay close attention to the bore, chamber, slide rails, and feed ramp. Use a high-quality gun oil to lubricate moving parts, like the slide rails, feed ramp, and other critical areas. Don’t over-lubricate the pistol, as excessive oil can attract dirt and grime.
Magazine Management
Keep magazines clean, and inspect for damage. Regularly inspect magazine springs and followers. Replace magazines as needed to ensure optimal performance.
Ammunition Prudence
Selecting the proper ammunition is paramount. Use quality ammunition from reputable manufacturers. Experiment with different brands and bullet types to find what performs best in your Evo SP. Avoid using reloads, especially while troubleshooting issues.
Seeking Professional Help
When problems persist, do not hesitate to seek the assistance of a qualified gunsmith. They possess the skills and experience to diagnose and repair more complex issues, and they have the proper tools. Attempting to perform complex repairs yourself can sometimes worsen the issue and could potentially compromise the safety of the firearm.
