Just what my Smith needed! 3/23/2019
I had stayed away from newer Smith revolvers because of their horrendous trigger pull. When I came into possession of a model 64-8, I heard about these spring sets in a YouTube video by MrGunsAndGear. I put these in and went to the range today. Im blown away at how much lighter and smoother the double action trigger pull is! I cant recommend these highly enough!

586-2 results 2/16/2019
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 dont have a trigger scale, but the difference is absolutely night and day with these simple mods. It took all of 30 minutes, most of that time spent polishing the rebound block. Do yourself a favor and buy it, its like a totally different gun now.

686 Plus now Smooth 7/17/2018
Polished all internal surfaces first, several good YouTube videos for instruction. Went with the 13lb trigger return spring and the hammer spring. Fired 100 rounds at the range Federal Hydra-Shok 110gr. Low recoil, Perfecta 38sp. 158gr FMJ, HPR 38sp. 125gr TMJ, Hornady Critical Defense, Fiocchi 357 125gr SJSP with zero misfires. Trigger pull light and smooth with better groups using double action. This is a new gun so it wasnt smooth before polishing.

Works Great after minor hiccup 7/5/2018
I initially had a problem with the hammer spring fitting/functioning in my very old 5-screw K-frame. Wilson Combat support quickly diagnosed my problem and shipped me a spring that they modified slightly to work in my revolver. The very slight straightening of the spring near the hook end resulted in a perfect fit in my old Victory model and gave me a lighter action. I combined it with the middle weight trigger return spring & couldnt be happier with the result. Great product and SUPERB customer support!!

Hugh Difference 2/13/2015
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.
 
My trust in Wilson continues to be well-founded 9/29/2013
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.

Smith and Wesson 28-2 Spring kit 7/15/2013
I installed this spring kit using the 13# rebound slide spring in my 28-2 Highway Patrolman. I did a trigger action job on it at the same time. Single action trigger pull is under 1#, and double action is about 4#. I filed about 1/8 inch off of the main spring tensioning screw. I love it. I highly recommend this spring kit.

Good Springs 2/12/2012
I have installed this kit in a K frame Model 10 with no failures to fire. For a defensive handgun I find that the lighter rebound springs do not offer aggressive enough trigger return, I have used the 14# spring with good results. In an N frame Model 325 using the reduced power hammer spring I had frequent misfires. I still gave this product 5 stars because I believe with this firearm any reduced power hammer spring would require tuning and depending on how light you wanted to go also tuning the ammunition. I would suggest replacing the strain screw and if you have a newer revolver, slightly reducing the diameter of the firing pin return spring.

Nice trigger pull, but... 4/13/2011
This kit gave a very nice trigger pull on my S&W 617, but in double action it caused light hammer strikes 60% misfire. Single action was not as bad; only 5-10% misfire. If you want to use this with a rimfire model, you will probably need to get a longer mainspring set screw for it to work properly. At the very least, WC should make people aware of the issue. The other big gunspring company that sells kits like this has a disclaimer and does sell a standard power mainspring for more reliable firing.

Just what the doctor ordered! 4/6/2011
This spring kit was just what the doctor ordered for my S&W 329 NightGuard! The lightened trigger pull and feel is outstanding! I enjoy the double action pull, as it is a 1000x times better than stock! I have recommended this kit to all my friends, and will order a kit for all of my 13 plus revolvers!

goooood 9/28/2010
Have an old 28-2 highway patrolman, realllly bad trigger. First changed out the main spring, then learned the recoil makes a big difference too. Used the 12# with about 2-3 coils cut off it. Works great, now I just need an india stone.
