Post a picture of the seam on the backside where the 2 grips come together.

I love the grips on my 226 Legion SAO, no fitting problems.

On yours, it almost looks like they took non-legion grips and added a Legion medallion. If you look at the area where the front strap undercut curve is, that area on my grips is curved to follow the frame. On yours its straight and does not follow the curve of the front strap...

A picture of mine for reference.

I've seen Legions with both style grip curves. I just assumed this was some running change SIG made.
