At least the common thread here is still the .45 cartridge!
They aren't Kahr's, but I have to recommend the recent Colt WWI M1911 and WWII M1911 pistol replicas, should you still be able to find them. Fabulous fit, finish, and duplicated original markings. Also, U.S Firearms Company of Hartford, CT, is coming out with M1910 and early M1911 replicas as well; check their website for photos. I purchased one of their O.W. Ainsworth M1873 replicas recently and they are beautifully made, with all of the little touches present, including markings and inspector stamps. Indexing and function are perfect, as well.
