Trigger Pulls: The Good, The Bad, and The Ugly

    I recently posted an article evaluating the Beretta ARX-100 rifle, and the feature that I feel was most detrimental to the shooting experience was the trigger, which actually maxed out a trigger pull gauge. My friend CJ is serious about distance shooting, reloading, and is quite handy when it comes to trigger work and as such he has a gauge.

    On measuring the pull of the ARX-100, most attempts resulted in a max:


    However we did manage to get it to read once after several times at 11 pounds, 8 ounces:


    After this experience, I thought it might be reasonable and prudent to put many other rifles (including two Beretta products) to the test that I feel are comparable in at least one category to the ARX-100.

    For testing, I dug pretty deep into the safe. I will also note that none of these have had any trigger work on them. All have completely stock triggers:


    A set of testing parameters were established:

    1. The same gauge used in the review would be used on all rifles
    2. Three attempts would be made on all rifles
    3. The median of the three tests would be collected as data

    The rifles were placed with their stocks on a flat surface and all tested by my business partner Patrick while I photographed the rifles (he has no vested interest in any rifle performing better than any other).

    Anyways, on with some results.

    I felt starting with the previous Italian service rifle was appropriate; the tried and true Beretta AR70:


    Which did much better than the ARX-100’s 11 pounds, 8 ounces:


    Next up was a Daewoo K1A1, Korea’s AR15.

    So with that we have a final pool of all data, arranged from the gun with the lightest trigger pull to the heaviest:

    And this fancy graph should help as well:


    This experiment was eye opening to me, and I hope that this data is pertinent to you choosing your next rifle!
