I've got a Wilson KZ45 compact on order and have had occasion to shoot a friends full size KZ. Obviously, I'm impressed with the Wilson. I have not shot the polymer Kimber, but handled one the other day in a gun store - I personally did not like the feel of the Kimber's grip. I've been shooting 1911's for about 10 years and the inventory includes a polymer SV (1911 wide body) that I love.
The SV is strictly for competition; the KZ will be for carry, but will see some match work for funzies
. BTW, most of my FTFs have been extractor related - so I think the Browning type extractor is a good idea. Hope this helps.
