There was some validity to the claim very early on in the development of the 320. You had to try very hard but with enough force you could get one to go off. That was rectified immediately and the fact that SIG beat out the rest and was adopted by Military is a testament to their RnD and quality. The rigors and protocol to get accepted By US military are very difficult. There is a bunch of speculation (key word) that the lawsuits are being driven by outside sources in an effort to discredit SIG who is arguably on a roll. All I know for sure is I love mine and have never had a pistol that was so ergonomically friendly to my hand. It is like it was molded for me. The 320s have changed the landscape much like Glock did/has.
