That is fascinating and certainly enlightening but it doesn t bolster the uncited statement in this article that the SIGs broke their frames in testing Though I wouldn t be surprised that something was going on under the table with the Berettas I was in the military when we did the switch from the old 45s to the 9 mm and the 9 mm was a troublesome finicky weapon not suited for most of the environments that we had to use them in The 45 might not have been pretty but it would take a lot more abuse than the Beretta would and keep firing But that s neither here nor there my only contention is that there s an uncorroborated statement in this article that nearly the opposite is reflected in other articles
