Well I took this pistol and my Springfield 1911A1 to the range today just to shoot some more to see what was going on. I started off with my Springfield .45 which I know I shoot OK. the target below was shot at 10 yards and is basically what I shoot with most pistols including my Springfield, Steyr S40, S&W 342 (actually a bit bigger groups), and my Cimmarron Arms SAA .45 LC, I also do this well with my brothers XD 40.

I then shot the FEG again, I shot more slowly and really paid attention to what I was doing because I wanted to know what the pistol was really capable of, I did much better than yesterday, but my groups were still about 8 inches. I thought I had brought one of those targets home, but apparently I didn't.
Then I asked one of the Range officers if he would be willing to shoot my pistol so I could see what somebody else could do, he had never shot a Hi-Power before and actually got bit in the process, but below is his grouping from one Mag (13 shots) using the same Winchester White Box ammo.

It seems that the fault is mine. Neither me or my brothers could do well with this pistol yesterday, in fact as Salted said, at first we weren't even sure where the bullets were hitting because they weren't even hitting the target.
I think Josey was right and it's the sights and maybe a bit of the trigger, but at least now I know the pistol isn't screwed so I have no problem spending a bit of cash to get it fixed up a bit.
BTW, Yes I feel like an idiot.
