i JUST BOUGHT SHIELD 9 , PLAN ON USING AS MY EDC, CURRENT IS A SIG P239, AFTER ALL DAY IT BECOME A LITTLE HEAVY. i AM IN CALIFORNIA, SO I NEED TO PUT NIGHT SIGHTS AFTER MARKET, ANY SUGGESTIONS?
I think what he's referring to is that in California you have two options: the "California compliant" Shield, either standard or the PC version. The non-PC CA compliant Shield does not have a factory installed night sights option. You cannot purchase a non-PC Shield that includes the factory installed night sights (SKU 10086) in California, unless you're LE.
