Why to change the trigger pull?
The S&W 686 Target Champion comes with a very fine trigger and good over- / pre-travel.
Although, the trigger pull on my model was very high ( for me ) and so I wanted to lighten it a little bit.
I usually do only target shooting with S/A, so replacing the rebound spring should help in that case.
My choice was the Wolff Springs rebound spring set, which includes five different springs in the range of 11lbs to 15lbs.
You need …
… not that much tools for this work, so here we go:
- a flat-head screwdriver, medium size, for removing grip and side-plate
- a flat-head screwdriver, smaller size, for removing the spring
For installing the new spring, I used an allen key, it worked good and a little bit easier for me. A small flat-head scredriver as listed above is also good for that – your choice!.
There is also a special tool available to remove that spring, too.
Let’s start the Smith & Wesson 686 trigger job
- remove the grip
- remove the side-plate ( arrange the screws to be sure to install them later in the proper way again )
Now you’re ready to change the spring, use the tool of your choice to remove the spring, then install the new one ( this can be a little bit of annoying work, but don’t worry, at the end of the day it’s not that wild )
I’ve done a short video during the whole process ( there are a lot of similar videos on the web, but I just wanted to show that I’m able to change the springs, too ) – btw; if you haven’t subscribed to my channel, go and get it – thanks! 😉

Smith & Wesson 686 trigger job – the results
I did six passes, so each chamber was measured also six times – the values in brackets are measured with the original spring, ch1 – ch6 is the number of the chamber.
| ch1 | ch2 | ch3 | ch4 | ch5 | ch6 | avg | |
| p1 | 1,257 (1,937) | 1,336 (1,923) | 1,294 (1,890) | 1,291 (1,928) | 1,384 (1,894) | 1,410 (1,778) | 1,329 (1,892) |
| p2 | 1,393 (1,882) | 1,316 (1,909) | 1,340 (1,797) | 1,349 (1,768) | 1,356 (1,859) | 1,350 (1,935) | 1,351 (1,858) |
| p3 | 1,372 (1,833) | 1,338 (1,823) | 1,257 (1,823) | 1,345 (1,831) | 1,374 (1,939) | 1,419 (1,915) | 1,351 (1,861) |
| p4 | 1,321 (1,872) | 1,356 (1,957) | 1,355 (1,882) | 1,317 (1,832) | 1,382 (1,982) | 1,430 (1,949) | 1,360 (1,912) |
| p5 | 1,390 (1,944) | 1,367 (1,871) | 1,253 (1,891) | 1,305 (1,878) | 1,373 (2,010) | 1,444 (1,992) | 1,355 (1,931) |
| p6 | 1,343 (1,935) | 1,363 (1,843) | 1,338 (1,895) | 1,291 (1,964) | 1,349 (2,039) | 1,423 (1,955) | 1,351 (1,939) |
| avg | 1,346 (1,901) | 1,346 (1,888) | 1,306 (1,863) | 1,316 (1,867) | 1,370 (1,954) | 1,413 (1,921) | 1,349 (1,899) |
So you see, the trigger pull weight has changed noticeably positively. The average trigger pull weight went down from 1,899kg to 1,349kg with the 11lbs Wolff spring.
That’s quite good for that small amount of money and a little work!
Later I will maybe deburr corresponding parts, but certainly not before my Target Champion has seen less than 1000/1500 shots 😉
Before you ask: The rebound spring only helps to lighten the trigger pull weight in S/A. Althought it helped also a little bit in D/A, where it came down from ca. 5,2kg to about 4,6kg – if you want to change the trigger pull weight in D/A, you need to change the main spring, too.
