I am really loving my Kriss. Everything but the trigger that is.

Post by hill92 on Mon Sep 24, 2012 8:46 pm

I took the Kriss SDP out to my range again last week. Zero FTE or FTF issues. It really is a great gun to shoot and I'm really glad I bought it.

The trigger is a different story. It feels like I'm rubbing two pieces of 80 grit sandpaper together with a 20 pound weight laying on top of them.

I have decided that I am going to have to do something about it. I've read the two threads over in the mods section and it gives me great hope.

How many here have performed the trigger job on their Kriss? Are there any springs or anything that I need to worry about flying across the room to never be found as I perform the disassembly?

I pulled my trigger pack over the weekend and disassembled it to inspect it. The pins come out easily. Once you take the tension off the hammer spring the hammer and spring comes out easily along with two black plastic round spacers. Then just go from there removing pins and paying careful attention to how the parts are oriented. If you are careful it is not a problem keeping up with everything. I separated each pin with the parts that the pin holds

It seems to me that there are a few obvious things that can be done. I imagine some of them would void any warranty if you try to send your KRISS in and the factory discover the mods.

First you can polish as directed by the other threads. What you need to polish is obvious once you get in there. Second, you can remove or lengthen one of the trigger return springs. Third, you could reduce the tension on the main spring (not the hammer spring) very carefully. I suppose you could tweak the hammer spring some but I would be worried about weak hammer strikes. I also think that some enterprising person could make new blocks that the trigger slides against out of delrin or other slippery material.

I also think that it's not a good design to have to remove the Pic rail to get at the top three Allen bolts to remove the trigger group. KRISS could have easily machined three access holes in the Pic rail to assit in removal of the trigger pack.

Hmm im not sure why you guys have issues with the KRISS trigger. I run mine just fine and fast.

I find the trigger on mine (brand new) to be..ok. It's a little heavy but not gritty. The polishing mod may make it slide a little easier. Leaving off one of the return springs has been noted to reduce the pull to around 6 pounds. I may just do the polishing since I find the pull fine.

My reset is what bothers me...a little long...but that just takes getting used to.

This is an SMG design...not a sniper rifle.

Yeah I find the trigger itself to be just fine. As was mentioned, it's not a sniper rifle!

However, After about 500 rounds my trigger is failing to reset and needs a little "bump" to reset and be ready to fire again. It's as if I have to double tap the trigger - once to fire and again to reset it. I'm not sure if it is just dirty down in the trigger group or if there is an issue with the sear (both are listed as possible solutions under the "Troubleshooting" section of the owner's manual). I'm really hoping it's just dirty! I'll be taking it apart tomorrow. I'll let ya know what I find.

Ok, I had my Kriss about 90% disassembled before I got nervous and decided that the trigger was actually pretty nice just the was it is.

I had parts stratetically placed across my desk as to not get anything mixed up. I got it all put back together and everything seems to work perfect.

Are you looking to send it to a gunsmith or you looking for someone local to your area?
