I have read the book, though I completely disagree with the conclusions drawn at the end that are completely unsupported by any fact in the book (some are even contradicted), it is not a bad book that looks at the history of Glock in the US. It covers the good and the bad, and even goes into why the good has won out over the bad. In everything there is trade offs and risks, there are also ways to reduce those risks and the book does cover that.
Unfortunately none of the review articles have come close to doing justice to the attempt that the biased writer made in being balanced.
