Wearing out a sear?

Wearing out a sear? Anybody experience this yet?

I shot about 100 rounds thru the Kimber with the new DIY Trigger Job, and it is where it should be, and I'm happy with it. I now compare it to my Springfield, and it is just to light. So much so that I think that it might be becoming a liability. I won't carry the Springfield anymore, for if the sear is going to fail, the pistol will become full auto at the moment of failure. I'm now thinking I might have to make a sear purchase, and maybe a new hammer.

My Kimber Custom has gotten extremely light on the trigger. No trigger job, just 2,600 rounds of ammo through it. I don't have a gauge to check the pull weight, but it's so smooth and easy with very short travel, it feels as though it has gotten lighter. I'm going to attempt to see if Kimber has a sear/hammer replacement recommendation for round count.

Found this. Perhaps it will keep you from going full auto.

HAMMER SAFETY STOP
The hammer safety stop is a notch on the
hammer which prevents it from falling fully forward
in the event of primary sear notch failure. It also
prevents fingers slip from the slide or hammer
while cocking the pistol, provided the hammer has
been moved past the stop. The safety stop is not
a manual safety! Do not under any circumstances
use the safety stop as a “half cock” position. This
misuse can result in damage to the sear, and/or
unintentional discharge of the pistol. The safety
stop position is an automatically engaging safety
feature and should never be engaged by hand!

Right, you are. I forgot about the 1/2 cock notch. At least I won't shoot myself if the ignition components fail. The Springfield is 25yo, and is silky smooth after 10s of thousands of firings. Feels like a Nighthawk I handled at the LGS. A keeper, even if after a Sear failure.

I think investing in a trigger pull gauge is a worth while investment. I've got a Timney and one of the first things I did was to measure all my guns and record the readings. Any time I suspect that something may be changing I can remeasure it and have a reference to check it against.

I'm beginning to think so. Start messing with triggers, the more info the better.

You just made me spend $37.98. It's all your fault.

I'll gladly take responsibility for that, you just made a smart move.

Regardless of what the gauge says, if you suspect there is a problem, visually inspect the sear/hammer engagement and the surfaces involved.
