Wilson springs are a great value
This is the best 10 bucks you can spend on your J frame revolver. The trigger pull was immediately improved and installation was relatively easy, even for a non-gunsmith.
Thumbs Up!
I purchased a new M&P 340 about a week ago. Lots of dry firing, but the trigger was too much. I installed the 13 lb. rebound spring and polished the internals (first time). It was much better. I went back and installed the 8 lb. hammer spring. It's so much better with still a lot of dry firing. I took it to my range this morning and fired 50 rounds of target ammo and 15 rounds of carry ammo. I realize it's only 65 rounds, but no issues and the trigger is so much better. 65 was enough with this little guy.
One down several to go
I installed this on my wife's M640, a DAO J-frame. With this kit it will be far easier to shoot and thus shoot more accurately. The action smoothed up and lightening the trigger pull helps. Highly recommend Now I have to install the kit in my other Smith revolvers.
Wilson Combat - the revolver experts?
I didn't, and doubt that most shooters think of Wilson Combat as revolver experts. Think again. I installed their spring kit for S&W J Frame in my Model 37. Before: 12+ lb. double action, 5 lb. single action pull. After: 8.5 lb. double and 3 lb. single action, testing 100% reliable ignition with 5 different loads from 4 different brands of factory ammo, tested double and single action! Easily installed after watching some Youtube instructional videos. The only special tool I recommend is the inexpensive S&W trigger return spring tool from Brownells. I installed the hammer spring and the lightest of the trigger return springs, which functions just fine. Pretty much same story with the Wilson K/L/N Frame spring kit in my Model 10.
Wife would not shoot S&W Mod.60 without.
Was looking to buy another revolver for the Wife until I installed the hammer spring and the middle trigger return spring in my S&W Model 60. Friends now want the kit for their J frame.
First Timers Can Install This Kit
First timers will have no problems installing these springs if they follow the procedures shown in several online videos. No special tools required. Using only a 1/8" wide flat tipped screwdriver had no issues with either the hammer spring or 13# rebound slide spring during installation into my model 042. Neither spring required cutting. As a precaution against a flyaway slide spring, looped waxed dental floss through the OEM spring and tied off to trigger guard prior to spring removal. Did a similar thing with the replacement spring prior to installation. Once the spring is installed, the waxed floss easily pulls free. Reduced trigger pull by 1#-14.0 oz down to 9#-3.5 oz.
Well worth the money
If you know what your doing, your can drastically change the trigger pull. This is definitely not a first timers project. If you have done gunsmithing previous, these springs with the appropiate polishing will definitely enhance the trigger pull.
Worked fine for me!!!
http://www.youtube.com/watch?v=JIUfmg1JulE was a good video showing me how to do this. I would recommend using some grease this makes the re-assembly much better
Worked great
Unlike a previous reviewer I phoned Wilson about the too-long trigger return springs. They said that was on purpose as different age J frames may have different length springs. They said cut them to the length of the factory spring you remove. If you don't have a lathe to make one you should buy one of the two trigger return spring installation tools sold by Brownell's. Buying this kit doesn't make you a gunsmith. I also reccomend the Jerry Miculec trigger job video from Brownell's.
It's OK.
The hammer spring installed fine. But the 13# rebound spring was too long to install. Which I don't understand. Emailed Wilson Combat for advice with no success. Had to settle for the 14# spring instead.....good thing there were three choices huh? Trigger pull was marginally lighter but very rough.
