Opinions on Trigger Pull Sets?

[Southern Raider]

Anybody have opinions on the various trigger pull sets available such as this one?

Seems like an easy way to simultaneously dump the MIM parts in the gun and get the trigger job to boot.

Drop-In Trigger Job

Howdy Southern Raider,

The drop-in trigger jobs are a crapshoot. You could wind up with anything from a nice,clean trigger to a 40-ounce, 2,000 rpm submachinegun...maybe unexpectedly while holding it in one hand. (Do a search for "Ken's Drop-in Trigger Job" and read it a couple of times.)

The fly in the ointment is in the hole spacing for the hammer and sear pins.
The fixture that was used to set the engagement angles on the group may
not be the same as the spacing on your frame...and it only takes a few thousandths of an inch to throw things seriously outta whack.

You can improve your trigger a lot with just a little prep work and attention to detail...and it'll probably be a lot safer and more reliable than using parts
from a source that haven't been checked for fit in your particular gun. Just
because a part or group of parts will drop in and work, it doesn't mean that they are working correctly...and it doesn't mean that they won't take
a sudden nose-dive in 3 or 4 thousand rounds.

I know that there are some folks on the forum who have used these parts,
or others like them and had very good results. That argument won't sway my thinking one bit. The drop-in groups may even be achieving an 80+%
success rate...but it only takes one uncontrolled full-auto event to alter the course of your life.

Just my 2% of a buck...YMMV

... Which is the reason these guns were designed to be fitted together by a trained and experiened final assembler. John Browning never designed a gun to be made with "drop in" parts. If the gun-makers often stray from the correct location of holes (not to mention not always drilling them straight) the drop-in concept will never work 100% of the time. I am suprised that it works some of the time.

I get the gist of what you're saying. Hmmm...

Do a search for "Ken's Drop-in Trigger Job"

Sounds like I need to read this, but my searches are coming up empty. Anyone have a link?

Hi, Old Fuff,

Well, JMB did intend that spare parts be installed by military armorers with an absolute minimum (as in zero) of filing and fitting. I know I have replaced many parts in GI 1911/A1 pistols and never had to do any special fitting or use any special knowledge. Everything really did drop in, like it was supposed to. Of course, that did not mean that the resulting pistol had a super trigger pull or any of the modern "bells and whistles", but it worked.

The problem with the clones is that many don't seem to be made to any real specifications, and it is almost as if dimensions depend on how a machine operator sets up on any given day. There seems to be no quality control, not even spot checking. As a result, even parts made by the maker of the gun won't fit always fit without hand work, an absolutely absurd situation.

Ken's Drop-In Trigger Job

Howdy again Raidr,

Here's the link. My bad...It was Ken's Drop-In Trigger GROUP...
not Job.

_________________________

In the beginning, the 1911 wasn't a drop-in/slap together undertaking.
When the rush for production came during the build-up and later the production rush for WW2, the Army Ordnance Department determined that the pistol could be reliable with much looser tolerances, and opened things up a bit so that they could be assembled by the average Joe with minimal training...hence the drop-in part was born, and it's still with us.

Current production 1911s and clones aren't built, but rather assembled
by people who were bagging groceries last month down at the Piggly-Wiggly via the "Selesct-Fit" method. This entails trying a part and doing a cursory check for function and passing it to the next station for the next part or sub-assembly. If a given part isn't right, another is selected until one is found that works....then there's always the tray of over and undersized parts in case none of the standard parts do...and this is why two identical Colts or Kimbers or Springfields that are assembled on the same day vary so widely. The final quality/fit/finish/function depends on
how determined and or patient and/or concientious that each assembler is
in finding the closest thing to "right" that he or she can. Hung over Monday or Vacation Begins Friday Afternoon can and does result in some
shoddy work in any manufacturing operation.

I've had the opportunity to talk with a man whose grandfather worked for Colt during the pre-war and the wartime production. He said that one of the old gent's gripes was that: "They just slapped them together instead of putting them together the right way!" Slap-dash assembly worked well enough...and it's still in practice. High-end custom shop guns and semi-customs...such as the Springfield Pro... are pretty much done differently
than the "Entry-Level models...and the cost reflects it.

Luck to ya!

It all depends on how the holes are drilled in the frame and where. Good Luck!
