Extremely happy I found your site! Kits came super fast. Instruction videos clear, precise, easy to follow. The best part, the improvement in my triggers! Keep up the excellent work Mr. Nelson and crew.
This spring kit installed just like the video. I'm a 73 year old vet with Arthritis in my hands. It made a useful handgun. Thank you.
This product is exactly as advertised and it is awesome! Really made a huge difference in the trigger pull. Makes the sigma 9mm much more enjoyable to shoot and handle. Very easy to install with both the video and printed instructions!
Shipping was prompt and the video instructions are spot on. Installation of the replacement sear spring was straight forward following those instructions however I don't feel like the new spring made much difference. Unfortunately I don't have access to a scale to compare the before and after but after dry firing several times prior as well as after the swap I am unable to discern much difference.
Great. Easy to install.
Great product and very fast shipping! Will definitely be ordering through this company again!
Original trigger spring was way to stiff causing inconsistent shot groups. With the new M-Carbo replacement spring, trigger pull is cut in half and getting much better shot groups. Thanks M-Carbo!!!
Simple and easy to install. Reduced trigger pull to 5lb 4.1 oz. Was 9lb 7.2 oz. pull. Turned this pistol into a nail driver with reduced trigger pull. Anyone that owns a S&W 40VE NEEDS to do this inexpensive simple fix. Instructional video made it a breeze. Will be using MCARBO accessories in all my firearms. Great company to work with.
Absolutely what the doctor ordered. Perfect fit. Easy to install and it works like a champ! Made a significant difference in the trigger pull & accuracy. Thanks, Chris and to all of you for a great American-made product!
Start off fast shipping! This is a must upgrade works perfect. Just a little challenge to install. Would highly recommend! You will stay on target with the lighter trigger pull. Only The best quality parts out there!
Great product. Gets rid of 8 lb. Pull to 4 lb. . Works great.
Ordered a trigger spring kit for my S&W sigma 40. Great service and received kit in a few days. Haven’t had a chance to install it yet but I look forward to it based on other reviews. Improvement is expected to be much better. Will update review once installed and fired.
It reduces from 9lbs to 6lbs trigger pull.
Great product much better trigger, smoother overall function.
The ordered parts arrived quickly. I had never replaced springs before, but with the excellent video they were easy to install. The trigger has a nice feel to it now.
The s&w sigma was a great intro priced pistol similar to Glock gen 1 but with a metal magazine the only draw back was that ridiculously heavy trigger pull this solves that issue. Shipping was fast and part super easy to install.
