I shoot IDPA and when the club running the IDPA has a 3 gun I shoot it. . . which has amounted to one time now. I've shot IDPA in SSP, CDP, and SSR and I shot my Colt 6920 with BUIS and Mossberg 500 for 3 gun. Yeah, it's a blast and I'd like to do it more. As for the FN, I've never shot one and didn't see one at the competition I was at.
