Put a couple hundred rnds through th XDm 40 yesterday after rifle. SD drill, pick up one hand point & shoot. Both hands. Needless to say, target has a bunch of non-center hits - but all on paper. Actually the sight is clearer with the fixed eye (other one gets done Mon) but still a slight double. Curious, seeing a spark on ejection haven't seen before. Everything looks OK, brass is fine. Any ideas?
