SPRING KIT, CUSTOM-TUNE, S&W K/L/N FRAME, REVOLVER

Installed mainspring and #13 return: SA trigger pull @ 3.25 lbs. Changed to #14 return spring: SA trigger pull @ 3.75 lbs. The gun is stock otherwise.

love it , it made a BIG improvement IMO .

I bought this kit for my 2 3/4" Model 69 that had a horribly heavy and stacky DA trigger from the factory. Out of the box there was a nasty burr on the spring hooks where they engage the hammer stirrup. I was able to clean it up with a file and polish it out, but it never should have left the factory like that. Thankfully they included 3 rebound springs, as anything less than the 14lb yielded a very mushy trigger return, but the 14lb was acceptable.

I purchased two sets of springs. I installed the first set on a Md 629 using the 12# trigger spring and the Wilson hammer spring. The Wilson hammer spring is shorter than the factory one but that is the way it is made and it works perfectly. After installing the springs there is about a 2lb difference in trigger pull, making a noticeable difference. After install I shot CCI and Winchester primers with no light strikes. 5 stars for kit one.

I received this kit and the mainspring was a LONG way from fitting into my new S&W 617 round butt. I am talking at least 1/8th inch wrong. No way to modify it to fit. The rebound

I installed this kit on a 66-8 and it dropped SA pull from a 5 lb to a 3 lb pull. I didnt measure DA pull but it is much lighter and smoother. Best money I’ve spent on upgrades. Don’t hesitate about doing this.

I very, very seldom post reviews but this product deserves one. The revolver, as stated in the title is a 586-2. I purchased used so the history is unknown. Some holster wear but appears to have been shot very little. I replaced the mainspring and the rebound spring with the 13 lb spring from Wilson. In addition, I polished the rebound block with an India stone. No work done to any of the other internals as Im a rank amateur at this.

I got my gun back from the gunsmith today after he installed one of these kits. I have only dry fired so far, but what a difference in the trigger pull. I would have to assume that it is going to help with accuracy.

I looked at three spring kits for S&W revolvers: Wilsons, Wolffs and Miculicks. The Wolff mainspring has a groove in it which has caused some folks difficulties with regard to where the strain screw contacts it. I wanted to avoid buying another strain screw or filing it down... A strain screw should be down tight & checked from time to time. The Miculick kit included just one rebound spring and, knowing that Jerry prefers a stronger pull to match his ability to cycle a revolver, I wasnt sure that his kit would offer a light enough spring {consistent with reliable ignition}. [Jerry often uses strong rebound springs because his issue is cycle time, not a lighter pull which is easier to keep on target.] The Wilson kit seemed like the best choice. I installed the reduced power mainspring and the 13 lb. rebound spring in my Model 625 -luckily, it was a good choice. The pull is much lighter and its still reliable - even with CCI primers. I also had my original 1974 S&W Model 67 which Id never modified and wondered what it might do with using the 12 lb. rebound spring with its original mainspring - that worked out well also. FYI - the Model 67 factory D-A pull was much lighter than the Model 625 made 35+ years later. So, I got two econo-action jobs for the price of one kit from Wilson.
