    My apologies, but I tried to follow along on the thread about strikers vs. hammers and got lost. So here is my specific question.

    On a Taurus Mil-pro 45acp, there does not appear to be an external hammer. But the gun is listed as SA/DA. Can you still have an internal hammer and have the gun shoot in sa mode after the first da shot? If so, How does the first shot get to be da if when you rack the first round, it cocks the internal hammer?

    I have to admit, I'm thoroughly confused. Be gentle.

    It is a striker fire with a Glock trigger. This is from their site.
    New Unique SA/DA Trigger System
    The PT24/7 Pro Trigger system solves the double action/single action dilemma once and for all. Figure 1 shows the trigger at full rest. When a round is chambered, the trigger sets in single action mode with the trigger traveling freely to the crisp break point shown in figure 2. The trigger resets to DA mode until another round is chambered.
    So, the gun rests in DA until its identical Glock like trigger is pressed. Wow, very original.

    Still lost. I went to the website, and they only show one figure but reference two. I looked at a video, tell me if this is right:

    You chamber a round, the first round is in sa. You fire, and do not release the trigger all at once, but slowly release until you get to the break point and can fire again in SA. If you release all the way, it becomes da again. Is that right?

    By not releasing the trigger all the way (releasing until a "click" is heard by disconnector), you are keeping a "pre-load" on the striker.

    When the trigger is totally released, the pre-load ceases, and pulling the trigger the next time loads the striker until the sear releases the striker.

    The videos on youtube were very interesting. I saw two misfires in one magazine load. Guy said it was still breaking in the gun after 450 rounds. Really? danf_fi explained it right. The gun works like any modern striker fire. They are just naming the operating system differently. This is a Taurus Glock with an external safety with bad reviews. Stick with the Glock or Xd. Go with the PPQ if you have more to spend.

    Yes, it is possible to design a DA/SA pistol with an internal hammer. I used to own a pistol with that exact hammer mechanism design, a HK P9S. Hasn't been manufactured by HK in decades. First shot could have been DA if you used the decocking mechanism.
