Most of the gun shops bash the sigma because they read it on the internet and have no first hand experience. I have been plenty of places shooting with my "***" Sigma and made more than a few change their opinion. The SD corrects 99.9% of the complaints with the sigma. I have the SD9, SD40, SW40V limited, and a M&P 40c. I often find myself carrying the Sd40 over the 40c. I do have 2 full size mags with xgrips for backups but still for some reason keep going back to the SD. The trigger just makes me feel much safer with 1 in the chamber carry.
