SPRING KIT, CUSTOM-TUNE, S&W J FRAME, REVOLVER

I purchased and installed the 14 lb spring first but didn't notice much difference. Installed the 13 lb spring and it's noticeably better than the factory trigger pull. I'm not very mechanically inclined so I looked up a couple of how-to videos on YouTube. But it should come with instructions. I also highly recommend purchasing the special tool for the trigger spring removal and installation.

14 ounce revolver with a 12lb trigger pull makes you look really bad at the range but not anymore. 13lb trigger with 8lb hammer spring, no failure to fire with over 100 rounds. Polished all internal surfaces first, several good YouTube videos for instruction. Federal Hydra-Shok 110gr. Low recoil, Perfecta 38sp. 158gr FMJ, HPR 38sp. 125gr TMJ, Hornady Critical Defense. Trigger pull light and smooth with tighter grouping, still not as good compared to my full size guns, thats me not the gun, but all in critical hit area finally. This is a new gun so it wasnt smooth before polishing. Now if only someone could make a reduced recoil spring for use with the +P ammunition?

I didnt, 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 any gunsmith supply. 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.

Just installed this kit into my 642 and went out back and tested it out. All I can say is WOW! Its like an eternity new pistol. Anyone who is thinking about getting these and is on the fence about, JUST GET THEM. Took me all of about 10-15 min to install then. To say Im happy with the outcome is an understatement. Thank you Wilson Combat for these and all the other outstanding products you offer.

purchased a S&W model 642 and after the first range visit I considered selling it. Then I discovered the Wilson Combat custom tune springs and decided to give it a chance. I installed the springs myself in 15 minutes and went back to the range for a redemption session. It was night and day difference in the accuracy and handling of the little 2 inch burner. It went bang every time with zero light hammer strikes. Every j-frame should have these springs installed.

Installation took 10 mins, outstanding results. *F*I*V*E* Stars on this product.

I ordered this kit for my J-frame, .38 Airweight. Reduced the double-action trigger pull great. Simple project for anyone. If you own a J-frame, do yourself a favor and intall this great kit. You wont be disappointed.

I installed the 14 lb. Rebound spring with the hammer spring on my 640-3.I also polished the rebound slide on the backside and bottom with a ceramic triangle spyderco sharpmaker.Im no smith,but it was a simple job and my trigger is much smoother and lighter! Functions perfectly. Thanks Wilson!

I have installed this kit in multiple J frames with no failures to fire. For a off duty/carry gun I find that even the 13# rebound slide spring gives good trigger return. Great engineering WC!
