True story! If any of you have/had one of these or have at least handled one stock, the trigger makes a Sigma feel like a custom 1911. The trigger in SA has every negative trait; long, gritty, creepy, and really high resistance. In DA, there are those who do not have the might to even pull it through its sweep *cough*1911 shooters*cough*. All joking aside, its pretty bad and i had no idea what it would be like before i ordered it (but for $140, who can complain).
The first thing i found was a set of Wolf springs for the slide, hammer and firing pin that purport to reduce the trigger pull and tame some of the slap-sting from the recoil so i put an order in asap for a set. I then took it apart to see what can be done to smooth out the action and found several surfaces with very rough tool marks on the hammer, sear, trigger bar and frame that probably account for all the grittyness. I went at the rough components with a sequence of 400, 800, 1000, 2000 sandpaper then also hit the transfer bar and trigger bar frame recess with a dremel and some compound to get that smoothed out too.
Once i get it all back together with the newly smoothed out parts, new springs and some Tetra grease, i cannot believe how much improved this is. What was previously a trigger measured in tonnage and felt like you were dragging a rusty boat anchor though a briar patch now is creep free and very light and smooth though the minimal pretravel with a crisp break at around ~5lb pull. What a difference!
Also, i had noticed that the feed ramp was very rough and had a washboard like surface that may have had something to do with some failure to feed issues where rounds were getting hung up in a 3-pt jam. Since i had the polishing materials out, i managed to get that surface smoothed up a bit more so hopefully that helps. All in all, a fun and inexpensive little undertaking with the cost of the gun included. Hopefully this weekend i can test it out and see how much these changes improve the usability of the pistol.
