    How consitent should your trigger break?

    I had my trigger checked today on my Kimber, 7 pulls lightest was 2.97
    heaviest was 3.67 it averaged 3.43 the trigger job was supposed to be 2.5lb 7 years ago. I know it's light for a carry gun,but what I was wondering is does it increase over time?

    Even if it increased over time (moving parts do wear) it seems odd that you have such a wide spread. It does surprise me that such a light trigger (2.5#) lasted anywhere near 7 years.
    Treat me good, I'll treat you better. Treat me bad, I'll treat you worse.

    You should replace your hammer, sear and disconnector with new matched parts, tuned to 4 or 4.5 pounds pull.

    I'd go with Ed Brown, Wilson, or Cylinder & Slide parts.

    The wide variation in your pull weights indicates worn parts and a potentially unsafe pistol.

    Just my opinion.

    It might help to dissassemble, lightly deburr and go back in with something like Tetra Gun Grease on your moving parts such as sear, hammer engagement and trigger bars. I have yet to do that with mine but the factory trigger seems OK to me.

    I agree - something is not kosher. Uneven wear on two mating surfaces is causing the two surfaces to meet differently with each action.

    I had this problem with a defective sear that was soft on one side. It wore unevenly and it surfaced as varying trigger pull.

    atleast you will be "surprised" when the gun goes off, theoretcially resulting in better grouping. Just an optomistic way of looking at it until you get it changed.

    You should absolutely replace the hammer and sear anyway with good tool steel parts because they are very likely "metal injection molded" AKA MIM steel.

    Kimber is real big on using MIM for critical parts & (I think) "powder created" MIM is usually between 97% to 98% density as compared to forged or tool steel...so my best guess is your hammer & sear are worn and likely are unsafe.
