    GP100 Spring Kit

    review-star review-star review-star review-star review-star
    What a great improvement in trigger control and shootability. I had the M-Carbo gunsmiths install the spring kit, which was accomplished in less than two weeks.

    Discovered flaw

    review-star review-star review-star review-star review-star
    The gunsmith discovered the trigger was flawed. This took a sharp eye. He ordered a new one and installed it along with all their other actions. It is awesome. Can't recommend them enough.
