I have a Les Baer Premier II .45 with a 6” barrel. When I first bought it, new in the box, it could not function reliably. It was just impossible to get through a magazine without some kind of failure. I fired a few hundred rounds with no improvement. Eventually, after it wouldn’t break in at all, I contacted Les Baer. Les Baer was reluctant to provide any service, and if I wanted them to look at it, I had to ship it to them at my own expense. To the best of my recollection, I would have had to pay for return shipping. Shipping with insurance was very expensive. I eventually brought it to a gunsmith who specialized in the 1911, and he was able to get it to operate. There were several issues to correct; all indications of poor quality control. However, it has never been as reliable as my other 1911s. I continue to think that this purchase was a mistake. I bought a reputation, and I was sorry that I did. I’ve thought of selling it. I have an old custom 1911 that I bought used, with a 6” barrel in .45 that cost less than half of what the Les Baer cost. It is reliable and accurate.
I will also say that when the Les Baer is disassembled, the machining doesn’t look any better than my Kimbers. When I compare customer service to other brands I‘ve owned, such as S&W, Wilson, Ruger, and Kimber, Les Baer falls short...
So, although the 1911 is my preferred platform, I don’t recommend Les Baer.
