I wont even touch the subject of which high end 1911 I think is better made. However, I will tell you that I am 100% satisfied with the Ed Brown Special Forces Carry that I picked up about 2 years ago. Brown 1911's are amazing. Fit and finish are top notch and I shoot it way better than any other handgun I own. The Gen III finish has held up extremely well too. Before I bought mine I checked out the same brands you mentioned, plus Springfield and Colt. If you are going to drop that kind of cash on a 1911, you cant go wrong with any of those options in my opinion. Just get out there and hold as many as you can at gun stores and if its possible, find a way to shoot some as well. Pick what feels best, and looks best
, to you and go from there. I cant even tell you how many high end 1911's I held and looked at before I made my final decision. Good luck with your hunt and get ready to become addicted!
