A significant number of reviewers report that the product does not consistently feed rounds when loaded beyond 13 or 15 rounds. This has led to frustration as users encounter repeated malfunctions, indicating a potential flaw in design or spring strength.
While some customers have reached out to customer service regarding the feeding issues, the responses of providing instructions for fixing the problem have not been well-received. Reviewers believe these fixes should have been addressed before the product was sold.
Positive comments reflect that users appreciate the additional round capacity the product offers. This feature addresses the 'lazy pinky' problem for users with larger hands, making it a desirable modification for some.
Several reviews indicate that installing the magazine bumper is straightforward. Users find it easy to fit onto existing magazines, which is a positive aspect of the product despite the feeding challenges.
Some reviewers have suggested additional enhancements, such as redesigning the side button for easier use when loading. This indicates a desire for ongoing product refinement based on user feedback.
