I have a Sig 229 9mm Legion that I am having FTE issues. It went back to Sig and they said they were not able to replicate the issue. I have been shooting Freedom 115 (new) and Speer Lawman 124. Today I shot 350 rounds and had 5 FTE- 3 with the Freedom and 2 with the Speer Lawman. Also, I have my magazines marked and it happens with multiple magazines. Any help or suggestions would be appreciated.
