Easy install. The instruction video points out key pitfalls and techniques. Having previously disassembled and serviced the trigger group, I didn't need the "special" tool. Small flat blade screwdriver works just as well. Just slide it in above or below the pin.



Easy, crisp pull. Took down 2 deer this season with spring set. No more fighting the trigger with cold fingers in 20 degrees. Line up, breath and squeeze.

I installed two of these kits - one on a 12 gauge and one on a 20 gauge. In both cases the stock trigger pull was at 6 1/2 pounds. After installing the new springs both trigger pulls were a shade under 5 pounds. This was an inexpensive/easy way to make a noticeable improvement in trigger pull -would definitely recommend!

Hey Chris just wanted to thank you for your e-mail about installing the parts i ordered. The sprig kit for the Mossberg shotty is awesome!!! I had already polished the sear in the trigger group of my 835 and that helped some it got the pull down to 7 lbs n change but still wasn't as light as I wanted so I hit the ole inter-web and found you guys. The order i placed actually got here before a order i placed the day before on Midway and that's really saying something cause those guys are fast!! About the springs for my 835 WOW!!! The install went as expected and the trigger is absolutely awesome!!! Breaks at 3 lbs and change and is crisp no creep whatsoever. I will highly recommend yall's products to anyone and the speed of delivery was second to none. Also Thank You for your service to our great country!!! its men like you who risked and gave their lives so people like me can be free!!
