    Sorry to resurrect, but...what's correct? The part of the spring that connects to the "body" is where I can see it on both the trigger pivot pin, and the trigger arm. This struck me as the most natural way to install it to prevent binding, looking at the setup, but I could well be wrong. I failed to pay attention when I took the pistol apart. Thanks!

    This IS NOT MY SPRING. MINE IS OPPOSITE THIS ON BOTH ENDS!


    Just the best pic I could find of said part.

    The pic is correct. For more info, see Randy's install video:

    Well...that sucks. I'll change it tonight. Thank-you for clarifying!

    Also, the trigger pull on my M&P is a dream. I got it second hand with stippling already done. Is there a way if I can tell if it has some aftermarket springs? The reason I ask, is that every now and then I get a light primer strike. This is using Remington White Box 9mm plinking ammo. Maybe that ammo is just known for hard primers?

    My spring's "foam thingy" is long gone. Does it matter?

    If it's missing the foam inside (and it was never there), and it's not red, it could be an Apex spring.

    If you don't know the life of the spring, replace it. The first thing I do to used guns is clean and respring them. I would also give the firing pin channel a thorough inspection, and look for any peening on the striker block.

    I cleaned out the firing-pin channel. It was so crapped up I didn't know there was a "vent hole" near the tip of the FP in the slide.
    My spring is silver. All of the springs in the gun are silver.
    I hate to sound ignorant...but I am. Striker block lives...where? I tore this thing down looking for a mainspring like in my P226...

    Apex springs are silver too, so the color alone isn't enough for an ID. Post up a picture.

    If the channel is clean, the striker isn't interfering with the FP safety plunger, and the striker tip isn't broken, it's time for a striker spring.

    Striker spring is the silver spring surrounding the FP, correct?

    Yes, but that thing you're calling the FP is the striker.

    To try and ID the spring, I'd like to see it removed from the gun.

    Where are you buying these parts, and are they the same for the shield?
