I waited a year and 3months for this gun. I got it this week on wensday and took it to the range on thrusday and after 50 shots the return spring broke in half,guide rod bent and a broke firing pin.
By "return spring" are you referring to the recoil spring or trigger reset spring breaking? Cause my trigger reset spring has broken.. Just spoke to S&W today and they're sending me a prepaid label to get the gun send in... This is the second "brand new" malfunction I've had with my Shield 9mm. This occurred either before or as a result of the very first shot I took with the pistol. My first problem was with the slide stop spring, which was not properly tapped into the front rail group. So when I stripped the pistol down to clean it before I shot it for the first time, I couldn't get the slide back on because the stupid spring was sticking out. Long story short, I fixed that, and then this stupid trigger reset spring broke. Very, VERY frustrated as well! See the pic below of the spring I'm referring to, and also a link to my posts about the first issue I had with this pistol:
