The Shadow Systems MR920 has gained popularity among firearm enthusiasts for its purported reliability and performance enhancements over the Glock platform. However, like any firearm, the MR920 isn't without its potential issues. This in-depth article explores common problems reported by MR920 owners, offering insights into potential causes and solutions. Understanding these potential issues helps inform your decision if you are considering purchasing an MR920, or if you already own one and are experiencing difficulties.
Common Shadow Systems MR920 Problems
While the MR920 is generally considered a reliable pistol, several recurring issues have been reported online and in forums. These are not necessarily widespread problems affecting every pistol, but understanding them is crucial for responsible gun ownership.
1. Magazine Issues
-
Problem: Difficulty inserting or dropping magazines, magazine wobble, and occasional failures to feed. These problems can manifest in different ways, and the severity can vary.
-
Causes: A common culprit is the interaction between the magazine and the magazine well. Tolerances may vary slightly from pistol to pistol, leading to inconsistencies. Also, aftermarket magazines not specifically designed for the MR920 might exacerbate these problems. Wear and tear on the magazine components themselves could also be a factor over time.
-
Solutions: Try using only factory Shadow Systems magazines. If the issue persists, check for any burrs or imperfections in the magazine well or the magazine itself. Minor adjustments (though ideally left to a qualified gunsmith) might be possible to improve fit. Replacement of magazines is also an option.
2. Extraction/Ejection Problems
-
Problem: Failure to extract spent cartridges, or spent cases not being ejected reliably. This can lead to malfunctions and potential safety issues.
-
Causes: This is often associated with ammunition type, extractor spring tension, or issues with the extractor itself. Weak extractor springs, especially after extensive use, could be a contributing factor. Using underpowered ammunition or ammo with inconsistent case dimensions can also hinder reliable extraction and ejection.
-
Solutions: Try different types and brands of ammunition to determine if the ammunition is the root cause. If the issue continues, professional inspection and potential replacement of the extractor spring or extractor itself might be necessary. This is best handled by a qualified gunsmith.
3. Trigger Issues
-
Problem: The trigger pull might be perceived as overly heavy, gritty, or inconsistent by some users. While a crisp, relatively heavy trigger is a feature for many, some might find it less comfortable than other platforms.
-
Causes: The trigger assembly design and manufacturing tolerances could influence the felt trigger characteristics. The design itself might feel subjective to different users.
-
Solutions: Many aftermarket trigger components and upgrades are available for the MR920. These could alleviate trigger pull weight and feel. However, modifying the trigger requires skill and caution; consult a professional gunsmith for installation and to avoid voiding the warranty.
4. Reliability with Certain Ammunition
-
Problem: While the MR920 is generally regarded as reliable, reports of malfunctions with specific ammunition brands or types have surfaced.
-
Causes: The interaction between the cartridge dimensions and the chamber tolerances can impact reliability. The firearm's tolerances might be more sensitive to variations in ammunition than other firearms.
-
Solutions: Thorough testing with a range of ammunition brands and types is essential to identify any potential compatibility problems. This helps users identify ammunition brands that reliably function in their particular MR920.
