JP Sauer and Sohn were founded in 1751 so they have a few years of firearms experience under their belt.
Sauer have produced some great innovative designs including the Sauer 90 also known as the Colt Sauer or Carl Gustaf M3000. This rifle had three rear camming locking lugs that engaged into three recesses in the receiver. It is probably the smoothest bolt action ever made.
The Sauer 202 was also innovative with its swap barrel feature and unusual tang mounted silent safety.
The 202 was superceded by the 404 which hasn't been a great success it appears. Maybe due to the decocking system and the alloy receiver.
Recently Sauer has released the 505 which goes back to a steel receiver and is cheaper than the 404.
The Sauer 101 has the pressed fit barrel and other than cosmetics it is the same rifle as the Mauser M12. These are the only centrefire rifles that I know of that use the press fit system.
As you mentioned Calvin the 100 does have a threaded receiver/barrel arrangement and it is basically the same rifle as the Mauser M18.
The early 100s did have a few issues but I believe they have long since been sorted.
The first Weatherby MkV rifles were made by Sauer I believe.
My wife and I own three Sauer 202 rifles and they are very accurate and a joy to use.
