After racking the slide the first 3 times, I decided to simply pull the trigger a 2nd time and it fired. Every FTF I had after that, I pulled the trigger a second time and it fired as well. Apparently, the primers are just too hard so I switched to WWB and have had 0 FTFs. With that said, this ammo was probably 3 years old (maybe more) - it's possible Wolf has changed their primers since then.
I'm not saying this is the cause, but I do know that Sig has had some out of spec trigger bars get out and they do cause light primer strikes. However, I doubt this is your case; I think the problem trigger bars fail on WWB, etc. too.
