Go about halfway down page 1 and you will see Larry Vickers post on Sig QC.
Here is what he said:
"I have seen some problems with SIG’s in some of my classes of late than I have never seen before - failures to fire, failure to completely chamber, etc. - I have heard some of the exact same things DocGKR heard and then I started seeing some bizarre problems leads me to believe there may be truth to the rumors
Up until recently I can’t ever remember having a problem in one of my classes with a SIG
Experience has taught me that all firearms makers have ups and downs - right now may be a bit of a down period for SIG
