The Sigma is an accurate, reliable, inexpensive pistol that has a heavy trigger. It is not a comnpetition pistol. It is not a Glock, but the grip feels better. People do not complain about a 12 lb D/A revolver trigger, but scream about the Sigma trigger. It was designed to replicate a D/A revolver trigger pull and does so very well. It is not a high end 1911 w/3.5 lb trigger...it works at 1/3 the price. If you only have $400 to spend on a defensive pistol, it works just fine.
In life, strive to take the high road....It offers a better field of fire.
