Overall Customer Rating of 25 Reviews:

Noticeable improvement

Nice trigger pull reduction. Best used with the aluminum target trigger. I will say, I had a hard time installing it. Not as easy as other reviews have said (I think they are bragging). Top quality product, though, ksg lower is just difficult.


True night and day difference!

It took me about 1.5-2 hours to install because my wifi wouldnt let me rewind the video when i needed to, but MAN THIS SPRING KIT AND TRIGGER MAKES MY KELTEC FEEL LIKE A TOTALLY DIFFERENT GUN!
It was my first time replacing a trigger, but the video was spot on and informative, and it was easier then expected.
Also when i received my parts, i realized that in my excitement to order them, i had accidentally ordered two spring kits. A quick email and MCARBO was more then happy to send me a shipping label to return the extra one!
Extremely prompt email replies, top notch customer service, and excellent quality parts and craftsmanship.

I will continue to be an MCARBO customer for years to come.

I you have any doubts in your mind about MCARBO, shake it off and order your parts, you will be glad you did! -glad is an understatement-
Thank you guys!!

SPring and Target Trigger kits are a must for the KSG

I purchased the combination of the trigger kit and the target trigger from M*Carbo. I followed the video instructions, and after fiddling with the lube on the trigger, and the rest of the innerworkings, I did finally get all the parts to come together, and adjusted the trigger to zero play in the trigger, which is way better than how the original setup was. Outstanding setup, great video for people who don't have fat fingers, and ultimately a 3.5 lb. trigger pull with no play - Outstanding!


Everything it promised!

Love the Spring (and trigger) Great video too. Its delivered everything it promised!

Trigger is 1000 times better now

I paired the springs and steel trigger and it got rid of almost all of the slop. Feels so much more solid and sleek. I couldn’t ask for a better trigger upgrade. Thank you MCARBO. I hope to see more for the ksg and rdb
