Nice part but very tricky to install

Rating:
Pros:
Cons:
The trigger is really nice and works great. I love the take-up adjustment and the break is pretty nice now and the whole assembly feels really solid. I did not upgrade my trigger or sear springs; a 3.5lb trigger on a shotgun doesn't sound like a great idea to me so I stuck with the stock springs. The trigger design is slightly different from stock in how it captures the trigger spring (it only supports it on one side) so a little bit of head scratching was required to get proper tension on the trigger spring.



The install was very tricky but most of it was just figure out how things work. The instruction video is useful but you have no chance of completing it if you follow it to the letter. The big issue is that reassembling the lower under full hammer spring tension is impossible. The pins for the trigger and the hammer bar are under so much strain there is no way to coax them into their holes on the other half of the lower.



I assembled the lower within the hammer spring under tension and you just have to be careful to make sure the sear is resting on the top of the hammer bar and doesn't pop down when reassembling. Same for the trigger snap catch on the safety. You have to be very careful to keep everything lined up and in place and then a small but of pressure on the hammer bar pin will get it aligned and it will pop in. It took me several hours and many attempts until I finally gave up on the video method and figured out a better way. So my advice is to understand how all the parts work together and then reassemble without having tension on the hammer bar.



I have done lots of upgrades, trigger jobs etc. on my 1911, Glocks, ARs and this was the hardest, most frustrating job I have ever undertaken but patience will get you there in the end. Well worth the effort. Look forward to seeing a few more upgrades from M*Carbo!

I cannot recommend this upgrade unless you are an above average do it yourself to a skilled gun smith. My KS7 lower is now in pieces and most likely will have to go to my local gun smith to have him install the trigger. It is not as simple as it looks in the video, video is misleading as this was not his first time installing this trigger. Needs to have some sort of warning of like "hey I did this 100 times and that is why it looks so easy". Again stay away unless you are an above average DIY or skilled gun smith.

This review is for the trigger and spring kit. Makes no sense to do one without the other! Trigger has no takeup and an excellent let off for a bull pup. I've done two other Kel-tecs, so had some experience, or so I thought.

I followed the video carefully and had everything go wrong on reassembly. That pesky slide release spring (SRS) was one culprit. THe other was the forward hammer spring pin (HSP). While trying to push it into place (part way together) the srs would make its way out--several times. Workaround was to use fine wire thru the srs aound the entire lever and twist off on the backside. Once done I was able to focus on getting the hsp pushed into its mating location on the opposite half. Other workarounds included taping the spacer in place, and found a tape roll with just the right diameter to hold the cocked hammer in place; much neater than taping! It took over 10 tries, but I finally got it together. I was not going to let this thing beat me!

I hope others can benefit from my experience.
