What I have is an EAA (Tanfoglio) Witness 'Hunter'. This is an all-steel, SAO 10mm double stack with 6" barrel. Unfortunately I don't see them being imported now--but I'd buy a second one in a heartbeat. It's as close to a 1911 as I think you can get in an all-steel double stack, and is a real pleasure to shoot. It feels wonderful, and the fit and finish are excellent.
My only others include a G20 (great gun I guess, not all that impressed), and a G29 (what I choose to carry consistently over all my other choices).
I don't really consider a Glock with a 3 1/2 lb trigger to be too very much different than 'SAO', at least not for self defense or action shooting purposes--where in my opinion the trigger is at the very bottom of the list of things you'll give a hoot about when the time comes.
I consider the G29 to be one of the most butt-ugly atrocities of aesthetics ever produced, short of the Nambu--and probably the single most ideal personal defense weapon available to a shooter who wants a nice balance of capacity and horsepower. I can't really say exactly why, but it feels far better to me coming out of the holster and getting on target than the G20, and I just prefer to shoot it over the G20.
While many fine single stacks have been and are being built, they're not for me if there's a double stack available--that's one big plus of 10mm just wasted, more or less, given you're not looking for an ultra thin gun for some reason.
The EAA Witness Hunter grip is less than 1/8" thicker than a government 1911--and I find it a bit more comfortable than a 1911. Again, a bit a moot point I guess if you can't find one. I think manufacturers such as Sig are really blowing it not taking full advantage of .40 cal stackability in a 'normal' sized frame.
The Hunter when I was clowning around with the EOTech sight--what a hoot
