i'm wanting to replace the rear sights on my 9e. Never have been a fan of the slanted novak style. I emailed ruger about the sight dimensions to no avail. He told me if a web sight offers sights for it they should fit. I am looking for a straight across type like on a factory glock or some low profile flat target sights. Wondered if anyone in this forum has tried replacing them and what they found worked. thanks in advance.
