I have several M&P 9s with the Apex both 1.0 and 2.0. I have one with the Timney Alpha. I prefer the Apex, but it seems the Alpha may be a little more consistent setting off primers. Even with Federal primers I get occasional light strikes with the Apex triggers.
Are you all finding a difference in primer ignition, Apex 1.0 vs Apex 2.0 vs Timney Alpha?
Or does this just very gun to gun?
Before I needed an optic I shot 2011s and never had this problem.
