To add to this thread are 3 of my 1911's. I have a few more but they are not 45 caliber so I didn't include them. The first two are both Les Baer pistols, with the two tone being a Boss model. The all stainless is a Premier II usually only made in blue steel. I bought it used for a very good price.

The Springfield TRP, below, is also in stainless. This is one of the least finicky 1911's I've every owned. It will fire and feed just about anything you put in the magazine. The only exception being Bullseye wad cutters, since they are load with so little powder they won't cycle the slid.

All my 1911's have beavertail safeties. I tend to grip very high and get severe hammer bite without it. My favorite load is 230 gr. ball ammo that I load myself.
I also have a Rock Island Commander in 45 caliber but I didn't have any pictures, so it's not here.
