I shot one in Vegas a few weeks ago, shot that, the Magnum Research BFR in .45/70 and the Smith & Wesson .500 Magnum
I am just waiting on the transfer to come through on my S&W .500
I found the Desert Eagle to be big and bulky, the shells eject out the top so you hope they clear your head otherwise you're going to get one between the eyes. I talked with the guys at the range and apparently if it does catch you in the head the shells can cut you and sometimes has issues jamming with the style ejector it has and they complained about reliability issues for long term use.
But man does it look mean...
