Changing Kimber 1911 sight
I have night sights on my Kimber TLE-II .45 ACP. I went to my first IDPA match and I didn't do badly, but my 7th decade eyes can't see the front sight in daylight as well as I'd like, so I sent away for a fiber optic Kimber front sight. Can anyone tell me if this is difficult to change and install or will I need a gunsmith? Thanks!
