I have a SA mil-spec with a decent amount of creep. The creep got worse after I tried "polishing" the sear my self to try and fix it. Rather than send it to the SA custom shop for a trigger action job, what are the odds of being able to get the vickers blueforce gear sear and dropping it in and having a clean break??? Is it likely that I will NEED it to be fitted?? Also, will springfield custom shop have a problem with the fact that I worked on my sear(i just polished two different surfaces, nothing too serious)??
