For a first gun...
I have a close friend that is looking to get a 1911, and he is the type that researches his options quite a bit before making a decision. He is getting a Les Baer Custom - the Premier II with some options tacked on. You can pick and choose your options when ordering from them, and their reputation is very high among those in the know about 1911's from what I understand. I have also spoken with my dealer about 1911's, and his opinion is that Springfield is one of the best bargains out right now. Speak to shooters and go to some other forums before laying down 1k+...
good luck.
Les Baer, Dave Lauck, Massad Ayoob - They all make great guns, but their custom work is at a level that your average gun owner just doesn't need, let alone afford. These are master craftsmen that have dozens of years of experience and most of their work these days is outsourced unless you are paying for their time specifically, which will cost you about as much as a new truck.
A Les Baer is going to cost you, at a minimum $1800, and that is with no options. This being your first gun, and you aren't even sure if you are in love with the 1911, that is a hell of a stretch for me. I personally wouldn't recommend dropping that kind of coin on your first piece. That's like handing the keys to a new 911 Carerra S to your 16 year old who just got their driver's license....
@ Dibby - If your friend is willing to drop that kind of cash on a 1911, do him a favor and recommend stopping by the Nighthawk Custom website - they make as good a gun, I would say better, than the customs listed above and it will save him probably a grand on the back end...
