Just finished with the trigger job, instruction video was very helpful and made the installation easy, with the sanding and polishing the trigger pull and reset is much smoother but the factory pull was 5.5 lbs. and after the new springs it is only 4.75 lbs. not close to the 2.5 lbs. advertised.

spring kit for my shield ,was good except for the firing pin spring ,too weak . called M*CARBO about it . they send me a new spring right away ,and that one makes my gun work flawlessly . thank you .And God bless .

this is one of 12 spring kits I have purchased, great up grades for little $, who does not like that

It worked as described. They have good videos that explains everything. The only problem is if it's a new gun the roll pins are hard to get out .

I ordered it and got it in 2 day. It was easy to install and it reduced my trigger pull from 5 lbs 10 oz to 2 lbs 7 oz
