The only two things I ever caution folks to think about when picking a 1911 is to make sure you pick the sights and grip safety you want. Choose wrong and you're going to limit your options, unless you spend some money having somebody grind or weld on your gun.
In this era of Glocks, most folks new to 1911's don't realize the great variety of 1911 sight dovetails and not all sight options are available for all sight dovetails.
