Hello to All, like many new guns today the trigger on My G2 28ga was over the top ridiculously heavy. I finally sent the trigger assembly off to Precision Sports a few weeks ago. they were able to take about 3lb off of the pull weight, which has made a big difference in shooting the gun ,not having to yank on the trigger.
David at Precision Sports answered all of My questions and responded to e-mails. I won't hesitate to do it again.

I haven't done this yet, just recieved my Viper G2 Bronze this week, but it looks like a quick swap of the spring will do wonders for these triggers.

This is labeled for the Mossberg version of our guns, with installation videos.

I have seen that video, The trigger group in My G2 is a lot different than the Mossberg and since Mcarbo have nothing actually dedicated to the Tristar G2, I figured just spend the money and Cry only once. I'm an Old Geezer. :lol: .

You made me second guess everything I’d read. Just pulled mine, it’s idebticsl to the one in the Mossberg video I linked to above. As long as you got it working and are happy is what matters though!

Looks like it should be easy to reduce the trigger pull on the Tristar G2 Viper. Once you've removed the trigger assembly, just punch out the trigger pin (Trigger Group Part #8) and remove the trigger slowly.

Then remove the Trigger Spring (Part 7) and replace with a lighter one. Reinstall in reverse order.

The G2 is different than the Mossberg, but after watching the installation video for the Mossberg, the job is very straightforward and easy. I did it in about 10 minutes because I was being extra careful and couldn't believe it could actually be that easy.
Perfectly acceptable trigger pull now.
It did hurt me to spend $18 on 1 little spring, but I don't regret it now.

Chas57...so you do not think it is necessary to remove anything other than the trigger pin (#8)? In the video for the SA-20 they remover trigger linkage. I looked at the manual and visualized what you are saying. I cannot see any reason to remove parts #10 thru #13 but I am not a gunsmith.

What about you Neanderthal...what was different about the G2 trigger and the video? I am just trying to make sure that this is as easy as some say. I am not real mechanically inclined but I build and repair computers so it is not like I do not have familiarity with taking things apart.

That's all you have to remove to get to the trigger spring. The trigger pin (part #8) is near the bottom edge of the trigger assembly. Just remove that pin and lift the trigger section out by grasping the disconnector (Part #10) and lift it right out. Easy peasey. The trigger spring will be protruding downward near the front end of the trigger section. Just replace it with a lighter one and reassemble in reverse order.

One other thing you should do before punching out the trigger pin is to de-cock the hammer. This takes the spring tension of the hammer spring out of the picture. Just be sure to recock the hammer and put the safety on before reinstalling the trigger assembly in the receiver. It's so easy a caveman could do it. :wink:

If I may ask, how much was it?

Sure You can ask... :) . They charge $85.00 to do the work which includes return shipping. I know it seems like a lot of $$ but down the road if there was/is/ ever a problem I don't have to hear "Grandpa Messed with that one". :shock: .....Old Geezer. :lol: .

Thanks, that does not seem too bad, if the trigger is unacceptable, I would do it also.

Chas is exactly right. Removed the one pin he indicated, pulled the trigger out, keeping my hand firmly over the hammer. Swapped out the spring, greased the hammer and clicked it back into place, lightly oiled the trigger group and reinstalled. Make sure when removing and inserting the trigger group that you keep the bolt release depressed. Trigger is significantly lighter. I do not have a gauge but it is much lighter. Also, this was first time removing trigger group. I have a couple hundred rounds through it but there was some packing grease that I needed to remove from the trigger group. Should have taken it out from the getgo. Next one I will remove trigger group when I do initial cleaning. Hope to shoot it tomorrow or Wednesday. Will let you know how it goes.

50 flawless rounds of Gun Clubs. Trigger is great. Very smooth. My timing was much better. Mcarbo spring is worth the $19.

Here's a picture of the trigger assembly with the parts and corresponding numbers as mentioned by others above.

I replaced with the Mcarbo spring today. $19 with shipping. Rediculous price for a little spring but it was worth it. Very easy to do and I'm lacking in mechanical skills. Made a big difference. Trigger is much better. Highly recommended.

I did this upgrade to my 12ga Viper G2 using the mcarbo spring kit.

Took 10 mins tops, only tool I used was a small punch

Trigger is definitely smoother now. Everybody should do this...

I thought this only worked on the 20ga, which is similar to the SA-20. The same part is used for the 12 gauge?

I bought the Mccarbo kit (one tiny spring) for mine. I also put some moly grease on the sear surfaces while I had the trigger group out. The trigger is much better now.

Yes, same spring as the 20ga

Obviously the actions are the same on the the mossberg and the viper g2.
