My 1911s won't be goin' anywhere. Got a little Kimber that's been with me for a dozen years now and is a sweet concealed carry solution.
Having 15 rounds is nice for a service pistol but I'm very comfortable with a 7+1 CC weapon and an extra magazine.
I can't speak to the durability as this isn't an issue I've ever had with my 1911 pistols and I'm too new to the FNP to comment intelligently.
