I am very disappointed in M*Carbo. I bought a Kimber Micro 9 based upon the YouTube video the president of M*Carbo made showing the trigger pull reduction on this exact pistol from +/- 6 pounds to 3-1/2 pounds. So, I buy the pistol and go to order the trigger spring kit and a couple tools from M*Carbo to perform the installation. Spring kit was showing back ordered. Contacted them and asked when they would be re-stocked and they weren’t definite, but were anticipating about a month. Over the 4th of July weekend it shows it’s available and I order it. Following the holiday I get and e-mail stating there was a backorder. Then I got a phone call from a very nice lady explaining that the trigger spring kit is in engineering and they are re-designing it and there is no timetable for the spring kit’s availability. So, I’ve yet to shoot a pistol I wouldn’t have bought given what the truth is about this spring kit. Here’s the link to the video for the now nonexistent spring kit. https://youtu.be/bbn-tkWj5S4 Maybe Chris Nelson would like to buy a brand new Kimber Micro 9 and an expensive leather IWB holster I have no use for?
