I have a full size Kimber 1911 Classic in 45. Ive had the gun for a few years now and havea prob with bullet impact and the non-adjustable sights. I have reloaded and purchased aton of different loads for it and all have the same problem. The sights are the original that came with the gun.

I was wondering was is there anyway tochange the point of impact without buying new adjustable sights. At 20yards the gun hits about 6inches straight left. Ive had other shooters try it and had the same issue. Thx in advance.
