There has been a lot of chatter about SIG’S quality control lately.  Statements that call it to question.
SIG started this themselves when they started offering a lot of 3rd party crap with the SIG stamp on it.  Holsters,  cheap Red Dots, bulky, overpriced lights… terrible stuff.
But this is mostly all in the past now and SIG has learned that lesson and taken it to heart.  What they are doing now is incredible.
SIG wants to be the best.  They want to offer the best to the American Gun Owner.  And to this right, they have to do it themselves.   This means they are bringing things in house. 
Optics.  SIG is quietly making some amazing optics, after headhunting the best talent in the USA for the project.
SIG is also rolling very high quality ammunition.
The QC on their guns remains stringent.   Any 22X gun is going to be top quality.   Questioning maybe their rimfire stuff… debatable.  But SIG’s core gun lines have never faltered.  And honestly probably better than ever.  Better than even the legendary “German Stamped” guns.  Yes, I went there.   I’d happily take a new M11 pistol over any German marked 228 or the like.  I have full faith and confidence in SIG firearms.  And SIG is one of the very few gun makers I’d bet my life on.
