I came here for accuracy answers to my X5 Legion... I was a 25yd bullseye shooter and can cloverleaf groups at 7-10 with almost any handgun... Except my Legion... easily the fastest gun I own and I use it in Carry Optics USPSA... but man does it group poorly. Sure, at 7yds it is "good enough" for USPSA, but when we start getting 20-25yd targets, it just doesn't cut it. Was hoping to find some answers, but I see it is much more common than word of mouth would let me believe. I've tried 115, 124, and 147gr bullets of various power factors. Nothing groups well. Was contemplating a barrel change. Has anyone tried that? Has anyone figured out the secret to improving the accuracy of these?
