come on now you dont add say a 4lb spring to a 10lb spring and end up with 14lbs total logic and physics disallow that. Guys it is a DA recoil dependent gun the striker must be pulled back by the action of the trigger. You can argue all you want but facts are facts the weight of the sear springs is less than the weight of striker.

The springs were added after the law suit because the gun was basically a Glock but priced right. With a Glock there is no felt weight with take up also follow up shots are very fast with the Glock as the reset is short.

S&W had to make changes to create a different trigger action which is why you have all those springs. With the Sigma you feel the weight of the trigger on your take up and you also have a very long reset. The reason the Sigma feels so heavy compared to the glock is the weight felt with take up and the difference in the action of the slide on the striker. It also feel gritty and creeps an insane amount because the sear is pushed against the plastic sear housing. Plastic against metal just doesn't give you a crisp trigger.

With the Glock the striker is pulled back by the action of the slide in a sense half cocking the striker. When the trigger is pulled the striker is only pulled back a little before it breaks. With the Sigma the sear is only reset by the action of the slide the trigger must fully cock the striker before it breaks which is why you feel more weight with the Sigma.


But by all means feel free to remove what ever parts you deem to be extra just dont complain when teh trigger doesn't reset. Or you start getting light strikes. If you want a match grade trigger throw down $3000 on a tuned race gun like a Wilson Combat.
