    Sig P320 Trigger modification for LESS creep.

    I just acquire Sig P320 X5 Legion, I will use this gun for the range punching paper no HD intent, after 500+ rounds break in I observed:
    - Trigger takeup distance is OK.
    - Trigger creep distance is NOT OK. For my style of shooting, the trigger creep is TOO LONG before the break.
    - The trigger pull weight to break is OK (3.5# at the lowest point of trigger. 4.5# at the middle of trigger)
    - Trigger reset distance is OK.
    Do you Aces know any company sell the "trigger modification kits" that will reduce the trigger creep to minimal.
    Thanks You.

    Gray Guns (Oregon) does good work and sells trigger kits. The Sig Armorer from Texas does too.

      Thanks Oddjob for recommending Gray Guns and The Sig Armorer. I picked the GG because of the price about half of TSA.
      Notes after the installations of GG :
      - The GG trigger kits came with two set of springs: competition and moderate. I chose the competition kits.
      - The trigger pull is: 2.5# at the middle of trigger, 2# at the tip end of the trigger.
      - The creep before the break is minimal, I am very happy with the creep.
      - P320 CA version has the manual safety so a little bit difficult than MOST of the P320 (which have no manual safety).
      - Installing the trigger bar is quite difference than what you saw on you tube (most of them no manual safety), I had to:
      . make the "new GG trigger" connect to the "trigger-bar" first,
      . connect the "trigger-bar" to the "FCU" (no "trigger bar spring" attached)
      . connect "trigger bar spring" to the "trigger-bar".
      . used the "special V screwdriver tool" to pry/mount/... the "trigger bar spring HOOK" to the FCU. (Or the spring is the last part to install).
