I installed this on a Shockwave that already had a pretty decent trigger at 4 3/4 lbs. I was hoping for a noticeable improvement, but only wound up with a 4 1/2 lb. trigger with the new spring kit. All and all, I don't think that it was worth the effort for me.

No light primer strikes on any ammo tried

Today (Friday 2-9-18) I fired off about 100 rounds of various brands of 12 gauge ammo. All went bang. I did have one failure to feed and one failure to eject using federal #8 bird shot but my buddy had the same issues with the same ammo when he tried it in his 870 clone so I attribute this to the ammo (Federal) and not the springs.



All the ammo had deep primer strikes so this spring kit must have been extensively tested prior to coming to market as it is the only one I've ever used that did not cause light primer strikes.



The trigger is really nice and smooth now.



Thanks MCarbo I'll be buying one of these kits for my Mossberg 500 as well.

I own 2 Mossberg 835s. I changed both of them to the new spring kit and it made a difference in trigger pull. One gun had a 8.1 lb pull b-4 changing and it dropped to to 6.14 lbs even though it feels lighter and the other had a 6.13 lb pull b-4 changing and it dropped to 5.12 after changing. I’m very happy with those changes.
