I first ran 50 rounds with a Ruger .22 as warm up...Which improved my .45 results considerably, all in all, i guess this answers my question : It was me, not the gun.
Quite happy with this result, especially since i'm a bit hungover this morning

I already indicated that the issue was fixed by training the operator.

Glad to hear you figured out the problem, svandamme.

Just for shirts and gurgles, in case this problem ever comes up again with another shooter, svandamme's situation sounds like a classic case of anticipating recoil. That causes most shooters to dive forward, hence a low shot. After a few magazines full, the shooter gets more relaxed and no longer anticipates recoil, then the shots come up to the POA.

Just a thought based on his description of events.
