Try a bunch. Really, I think it's less of "What 1911 should I buy" and more of "What features do I want my 1911 to have"
Honestly, regardless of what opinions you are going to get.... and you will get them...... there are quite a few 1911 manufacturers that make a fine quality product.
Personally, I wouldn't PuPu a 1911 made from Kimber, Colt, RIA, Springfield, Remington, Norinco, etc. etc. etc. Although you will hear horror stories from any number of people, and singing praises from just as many others for each one of those brands.
The real thing to look at is your budget, and your choice of features, and the selection will more than likely make itself. My choice for a first 1911 for example.... I like stainless, prefer night sights, can't stand external extractors, wanted a 4" barrel, , preferred a bull barrel, don't want ambi anything, wasn't concerned with whether or not I had a drop pin safety, didn't want a rail, and had a budget of about $900. I bought a kimber Eclipse Pro II, and couldn't be happier.
Do your homework, figure out what you do and don't want, then revisit your question. I'm happy to let you try the kimber, as Im sure most of the 1911 folks here would be happy to let you try theirs as well.
