I bought a Super a short time ago that was made in 1966 that shows holster wear but with very few rounds thru it. The rear sight was screwed down tight which was odd, so I checked the front site with a NM like barrel to find the OM site an 1/8" short, or low. Now that is a dramatic diference in a short barreled revolver. I havn't been out to shoot this thing yet so this may be premature but is this gonna cause me some grief when I use med-range loads as I normally do these days? Is there a history of Ruger using the short front site by error, or do I just need to go shoot this thing and find out? Chief aka Maxx Load
