When it comes to 1911/1991 models, I am not terribly picky. I have a Colt M1991A1 Stainless that I bought NIB and I am perfectly happy with it. I have had chances to shot the Kimbers, the Paras, the Les Baers, and all the other customs, and they are nice, but they are not something I am willing to carry and have get knackered about in the field. Since I want to be able to carry my sidearm anywhere, I do NOT rpt NOT want the best fit and finish nor do I want to blow two grand on something I KNOW is going to get beat up!
THe principal difference between a custom and any stock 1911/1991 pistol is to be found in fit and finish. Since I do not shoot competition, and my scores are not measured in group size, I don't need a pistol that shoots one hole at 25 or 50 yards.
Don't let me stop you from spending the money if you really want to, but bear in mind the intended use of the pistol when you buy it.
You will also find the various Government Models surprisingly easy to tune and tweak, and parts are available anywhere. Most of the improvements in my M1991A1 were made with a Dremel and a polish set, and that gave me a trigger comparable to a $1500 Kimber. Accuracy is more than accpetable for my needs and uses, and I do not have to worry about the finish or anything else.
WHen you get into the Paras, bear in mind that they made their name with the "widebody" 1911 clones and tend to use a double stack mag. WHile there is nothing inherently wrong with the idea, I do HIGHLY suggest that you make an opportunity to try one and fire it before you seriously consider buying one, as the wider grip does pose a problem for some shooters. You are better off finding this out before you spend a bunch of money on the thing!
