Proficiency requires you to understand not only your tools, but mostly yourself. I have been known to be a big advocate of systems that are not necessarily popular. Whether it is using a less popular manufacturer or using a different and less popular trigger system, I often encourage expanding horizons and being more versatile as a shooter.
I myself have had the fortune to experience and witness the fact that in order to increase proficiency in whatever shooting style you choose, you must be willing to get out of your comfort zone. I encourage you to learn how to shoot with many different trigger systems and in as many formats as you can, from competition to bullseye shooting. Adding stress in different ways can allow you to learn not only about the platform you are attempting to adapt to, but also about yourself.
