Reading internet threads really isn't research. Its a good place to start if you know who you are talking to, but talking to Jim-Bob or Bubba about why they like or don't like something is meaningless....they have no credibility. Read some reviews by credible sources. Most are very positive about the Kimber rifles. Or better yet, buy one or shoot a few on your own.
I have to respectfully disagree with you on this. You can do research on the internet. Take this forum for instance. I don't know any of the members here personally. But after reading numerous posts I can reasonably conclude that there are some very talented gunsmiths here and very knowledgeble and experienced LR shooters. It's true, one should always be cautious and even skeptical about information on the internet or most any source for that matter, but when you start reading the same thing over and over from different sources and see trends, that tells me there is some credibility to it.
I have no desire to buy a Kimber based on what I have read. When I buy a rifle I want reasonable assurance that will work well especially at Kimber prices. I like companies like Cooper and Sako who have excellent QC and test their equipement before sending out and offer an accuracy gurantee. These are the only two companies that I would buy a rifle from for that reason. Other than that I would go with a custom from a good gunsmith.
Are there issues with some Kimber rifles.....probably. Anymore than any other manufacturer....probably not.
My opinion is they do have more problems than other manufacturers based on the fact of how many more complaints I read. Every now and then I read a complaint about a Remmington or Ruger, etc., But I honestly think I have read more complaints about Kimbers than all the other manufacturers combined. That's a trend.
Personally I would look at Sako, they may not be as light (don't know) but I think their syn. stocks feel better.
