Beretta M9A4: Ensuring everything is running smoothly
This video discusses proactive maintenance schedules for firearms, drawing parallels between a Glock 19 Gen 5 and other platforms. The instructor emphasizes replacing recoil springs around every 7,000 rounds and performing a complete slide refit, including all spring-loaded components like the extractor tooth, every 10,000 rounds to ensure peak operational efficiency. This approach is presented as a method to maintain reliability, even if individual parts might last longer.
