Have a Taurus tracker 627 in .357 and am totally a newbie. I had a few instructors and officers shoot it the other night and they ALL made comments on the very light trigger pull. Is this something I can adjust on the gun , or should I take it in? After they all made this comment, I did notice that when shooting it single action, it doesn't take much to set it off, but I don't notice it shooting it double action. Just wondering if anyone knows about the model and if it's user friendly enough for me to adjust the trigger at home. thanks guys
