    Is there any detrimental effect when a TM1 the trigger coil spring gets weak?

    Thanks

    Depends how weak? Stronger spring creates more friction so it can change the force required to make the gun go bang. It can mess with the release triggers a little. As easy as they are to swap out why would you wait?

    You can also get light hits on the primer.

    The trigger pull is lighter than I would like 2.5 lbs. Would a new coil spring increase trigger pull?

    A tiny bit. The only friction due to more pressure is at the sear and on a pin. Depends on how coarse the sear is. Springs are cheap.

    Coil perazzi trigger rocks!

    If the sear is messed up a stronger spring could make it fire early or upon closing.

    Sounds like it might be time for a new hammer as well as the spring ... WPT ... (YAC) ...

    As thick as the coil spring is in a TM trigger I don't know if you would have to ever change one. I have never changed one in any of the TM guns I have owned

    Springs? no, never
    Hammers? You bet, more than once. Shamus and I walked into the Ithaca/Perazzi building one year with 3.

    I still remember his remarks to the guy as he put them on the counter

    "I don't want say anything but,,,,, THIS SUCKS."

    Of course that was back when the gun companies gave a hoot about their patrons.

    The response from the tech?

    No charge, do you want to wait or come back in about thirty minutes?

    We will come back
    BEER TENT!

    Can someone tell me why it is OK to recommend and/or promote any number of 'smiths and stock makers and one in particular has always been a fine source and info resource for me is persona non grata and cannot be named?
    and my posts like this always get deleted and I'm threatened with banning?

    just curious

    As far as broken hammers my solution was what I did back in the day to my high revving racing engines, more precisely...connecting rods. And that was to contour all sharp edges. Same procedure on the hammer. This relieves stress cracks. If I could have shot peened the surface area, I would have done that also. Did it work...you bet it did.

    If you look through the peep hole where the sear and the hammer catch is, you will see that the sear is slightly angled into the hammer angle cut. If the spring is stronger it will increase the poundage of pull, or visa versa. You are probably talking a couple ounces. The stronger the spring is the more force is compounded to the top of the hammer, which can sometimes break the hammer if excessive. These are hardened surfaces which makes them brittle. Fine line there as far as force, and the leverage created smacking the back of the receiver as a stop.
