Thread: Beretta PX4 trigger group

    Question Beretta PX4 trigger group

    Greetings,

    I'd like to remove the trigger group of my Beretta PX4, but am stuck.
    I was able to remove the mainspring, but no clue what is next.

    Send me a PM with your email address and I can send you a PDF with the full tear down guide.

    15.This step is one of those that cannot be
    properly photographed. With the hammer in
    cocked position, look inside the top of the
    frame on the right, and use a fork-tipped tool
    like the one shown to push down the rear of
    the small rectangular locking spring. While
    holding it down, use another tool to nudge
    the tip of the top retaining cross pin toward
    the left. This slim pin passes through the
    hammer pivot, and its head is fully recessed
    into the grip frame on the left side. This is not
    an easy operation.
    16. Remove the upper cross-pin toward the left.
    17. With the hammer in forward position, move
    the rear sub-frame out upward. You will have
    to dis-engage it form the trigger bar as it
    exits.

    I'm interested as well. I just picked up a full size PX 4 with the Beretta competition trigger pack.

    Since this was originally posted, Ernest Langdon put out a video taking it down, to replace the hammer with his bobbed hammer.

    Remember that top pin goes through the hammer holding pin, and that is the tip you need to be on.

    Successful installation! Adding a WC 12 pound mainspring next.

    The first time is the most scary, after that it gets easier. (3 PX4's in my case)
