Mornin' ladies and gents. I saw my first (Colt) catastrophic MIM sear failure
today.
I got up early to make coffee and get the dogs out for their A.M run, and
went to my truck to fetch a pack of Camels that I'd left in it. Door was
locked...which isn't my habit. I saw a Colt pistol box on the floorboard with a note taped on it. Note said..."Check it out. Trigger feels weird and the
hammer falls to half-cock on every other shot. Be back at noon."
Well...That explains why the Labs went nuts around 3 this mornin'.
Good dogs!
Okay...Hmmmm. I cleared the gun, cocked it and pulled the trigger.
Rough, rollout break...not too light, but not exactly right for a stock Colt.
Poured a cuppa turbocoffee and started breakin' it down. As I lifted the
sear spring out, I saw a sliver of metal. It was the sear crown...about
.050 inch of it at the narrow end, and probably a 64th wider on the other. The gun is a mid-90s production LW Commander that's probably got
5-6 thousand rounds under its belt. Not heavy use, but not pampered
either. He bought the gun from me 4 years ago to carry off-duty.
I had a lightly used Colt MIM sear that I took out of that stainless XSE
when I upgraded it. It dropped in and worked with very little massaging,
which speaks well of Colt's parts interchangeability...The trigger pull is
about where it was with the old sear, and firing 10 rounds in two-shot groups didn't indicate that there was a problem. Don't know if he'll be okay with another one just like the other one...I'll advise that he let me refit
the gun with a steel sear and disconnect. If he blows it off, I'll call his wife and get her on his case.
COLT!!! ARE YOU READING THIS?
Luck!
