Secondly thanks for posting the extra info on the lawsuit, does read like a lot of quality issues.
Kinda weird issues, not really typical of Sig pistols.
Believe it or not, just about every handgun manufacturer that supplies to LE has run into a situation similar to this. It has happened to Glock on many occasions, but also S&W, FN, H&K, etc...even Colt back in the revolver days. There always seems to be that one customer where everything just goes completely wrong for the manufacturer.
