Here’s what I would recommend for the feeding problem. Sigs have much tighter tolerances that does a Taurus. So try this
Shoot 50 FMJ rounds. Clean the gun.
Shoot 50 more FMJ rounds. Clean the gun.
Shoot 50 more FMJ rounds. Clean the gun. Lubricate it well according to the manual.
Then put 100 FMJ rounds through it. Clean and lubricate it again.
I’ll bet that takes care of the problem. If not send it in under warranty.
Good luck to you.

Just got back from the range. I ran 30 rounds of Fiocchi and 50 rounds of Remington FMJ through the Sig. It ran flawlessly. I'm now thinking that lubrication was the problem. Prior to our last trip to the range I had just used CLP for cleaning and lube. This time I used some Tetra gun grease on the slide rails. No FTFs or any failures of any kind.
Ran another 100 rounds through my Taurus PT111 G2. For some reason I can shoot this gun pretty well (even better than my CZ-82). Although I've only run about 350 rounds through her, I'm ready to trust her enough for everyday carry. 0 failures is 0 failures. :)
