How do you reduce trigger pull on a Series 80?

What is the basic process for lightening the factory trigger pull weight on a Colt Series 80? I've heard its just a couple of inexpenseive parts, right? I'm new to the 1911 world so I thought I'd ask here. Thanks!

Replacing parts is not the answer. Fitting the ones that you have is. Any reputable smith should be able to do a trigger job on a 1911 in his or her sleep.

This...


you don't have to remove the 80 Series parts to get a nice trigger.
My Remington R1 is at ~4# and is a decent trigger using stock parts.
In the next week or so i should have my parts to build it and i'm keeping the 80 Series parts in it.

I replaced the stock sear spring and trigger in my Colt Mk IV Series 80 Government Model.

The spring gave me a 1-1.5 pound reduction in pull weight and the trigger allows for a longer reach for my trigger finger. Minor fitting to get the trigger in and the spring was a "drop in". For less than $50 I am very pleased with the results.

Here are the parts I used...

I didn't know C&S made Colt's springs...

There must have been a change to the factory springs since I bought this pistol new in 1984. There was a noticable difference when I changed it out with the C&S sear spring.

The Wilson trigger didn't lighten the trigger pull, but the added reach and overtravel screw made it fit me much better. This isn't a range gun and I wasn't after an ultra light trigger pull. However, these modifications made a self defense pistol trigger just a bit better.

C&S doesn't make the Colt spring, they (as well as EGW) use the Colt spring.

the reason why there was a difference is because Colt adjusts the spring to achieve the correct trigger pull for the gun (when you buy it new). when you buy a replacement spring, it'll lighten the pull because it's not adjusted.
when i swapped out the factory spring (to the Colt) in my TRP Champion the pull went for 4.5# down to 2# before i adjusted it back up to 4#

also make sure you have the proper pre-travel/take-up since you installed a new trigger.
