Does not fit ruger sr1911 10mm - Kensight LPA TRT Trijicon Rounded Tritium Pistol Night Sight w/ 0.200in

I purchased this for my Ruger SR1911 10mm because of a recommendation on this site I can no longer find. If you got here looking for night sights for this pistol based on that recommendation, don't get this version. This isn't Kensight's fault and they really shouldn't be a 3 star as this is a well made sight. However, I wanted to bring attention to the fact that the "expert" advice from Optics Planet about this fitting an SR 1911 in 10mm is not correct. The front sight fits fine, so now I have a useless rear sight that is glowing in my parts bin right now and for the next 10 years.
