In essence when Sig came out with the Legion they put the slides to looser tolerances than the X5. Evidently its the same issue with the new CO version (name I forget). As was noted above, one way around it is to find an actual X5 (not X5 Legion) slide.
Agreed, but remember its geared towards competitors who want to shoot Production/poor man's Open (CO) without major mods, so a round count is expected.
Personally I have an X5 with the Legion grip. Its worked well except the dissassembly lever sheared off and is being replaced. Er...what...?
