From Apex Tactical:
Due to Sig Sauer’s recently announced “voluntary upgrade” of the Sig Sauer P320 pistol, announced on August 8, 2017, Apex Tactical Specialties, out of an abundance of caution, has chosen until further notice to suspend sales of those aftermarket trigger products specifically designed for use in the Sig Sauer P320.
Additionally, for those customers that have purchased an Apex Curved Advanced Trigger, part# 112-022, due to how closely the Curved Advanced Trigger’s design reflects that of the current Sig Sauer stock factory trigger, we are asking customers to stop using this trigger and to please contact Apex Customer Service at (623) 322-0200 of Guns@ApexTactical.com to return the trigger in exchange for credit towards any one of our Apex products.
Regarding the Apex Flat Advanced Trigger, part# 112-021, and the Apex Flat-Faced Action Enhancement Trigger, part# 112-020, Apex engineers have conducted controlled drop tests at the -30 degree angle with each of these flat triggers and have not had a discharge occur. HOWEVER, because this is too small a sample, and due to the fact that Sig Sauer has indicated that its voluntary upgrade will include more than just the trigger, we advise caution and warn against accepting use of either of these two Apex triggers as solutions to the factory drop safe issue.
