KEL-TEC KSG Aluminum Trigger

This replacement trigger is actually quite a nice upgrade. I was a bit on the fence about whether it would actually help or just end up being an aesthetic mod, but the trigger feels nice, has less pull (when installed with the spring kit), and takes out all the pre-travel. The install was a bit daunting at first, and like the guy in the install video mentions that one spring WILL try to go flying, but honestly it wasnt terrible. Its no drop-in, but probably what I'd call the next best thing. Worst part was trying to get the safety block to line back up with the flappy part of the trigger, but I ended up getting it after 2 tries. Overall I'm very happy with this trigger, really makes me want to use my KSG more now.

Trigger break and reset feels nice light and crisp now. No flex or dead space in the trigger now.

The trigger is the worst part of the KSG and this makes it perfect.

Install was challenging but doable. I couldn't get the pins and everything to line up with the hammer back and safety in the safe position.

Letting the hammer go forward and putting everything together with the safety in fire position worked effortlessly on the first try.

Thanks mcarbo, your products are 10/10.

I believe there is an installation service if the install is too much for you

Just upgraded with the trigger and spring kit. Mercy! This is sweet!! Great quality and excellent install video. I had no issues installing this, take your time and step thru it just like the video.

So I decided to take on the trigger and spring replacement on my own. Everything came apart nicely, the trigger change was easy. This is where the job gets next to impossible!!! Trying to install the trigger assembly is very very difficult , I have managed to install it 4 times (yes 4 times as if one pin is misaligned you have to take it all apart and start over) but have been unsuccessful in putting together the two body halves. The main problem is the pins that need to be aligned perfectly are under tension and do not line up at all. It has been three hours trying to get it back together and still haven’t been able to do it. It is highly recommended that a gunsmith do this job. I now have given up on reassembly and will just gather the parts and put them in a box and when I can afford it take it to a gun shop and have them finish the job.

M-Carbo's trigger and spring kit for my brand new KelTec KSG brought the trigger from the absolute worst ever (out of a very large collection) to the very best (at least for my shotguns). When I first got the KSG, the trigger made the gun unusable and measured an erratic 10 to 15 lb pull. I know this pull isn't typical for the KSG and with some polishing of the sear and trigger bar, I got it down to about 7-1/2 lbs. Still not great, and still a ton of slop in the pre-travel. After installation of the M-Carbo trigger and spring kit, the trigger pull is now 3.6 lbs and pre-travel is very small and adjusted to my liking. Most aftermarket triggers yielding this much improvement are going to cost well over $100 or even $200. It's the best trigger of my shotguns and vastly superior to my 3 other bullpups. Yes, the installation isn't easy and can be frustrating, but follow along with the video and you'll succeed. The install might seem tough, but when I finished, it worked perfectly.
