Reviewers generally find the installation straightforward, often aided by Apex's instructional videos. Many were able to install it with minimal tools, highlighting its user-friendly design. However, some noted specific challenges, particularly with the trigger spring, which required patience.
A significant number of reviewers reported better trigger performance, including reductions in take-up, creep, and reset distance. While some experienced substantial improvements, others felt the changes were marginal and did not meet their expectations.
Several users flagged issues with fitment and tolerances, expressing frustration over not being able to achieve proper engagement with the trigger bar. This indicates variability in manufacturing that may affect some models more than others, leading to a need for custom adjustments.
A common concern among reviewers is that the trigger pull weight is heavier than advertised, which disappointed some who expected a lighter pull for competitive shooting. This aspect suggests a need for clearer product specifications or improvements in manufacturing.
A few reviewers noted inconsistencies in product performance based on their specific model of the P320, leading them to question the overall quality control. Some reported significant improvements, while others were dissatisfied, suggesting a need for more stringent product checks.
