Wilson Combat Custom-Tune Spring Kit, S&W K/L/N Frame Revolvers

My trust in Wilson continues to be well-founded..

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..

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..

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.....

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!..

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..

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.
