As others have said dieseling 'normal; with these.
It's NOT the cause of inaccurate shooting tho.
Just spend a lot of time getting the 'feel' of the gun and don't feel the need to fiddle with sight adjustments at this stage. Once you find that your shots are starting to end up on the same place is the time to start thinking of sight adjustments.
Two 'common' faults that people using these pistols are their grip and 'anticipating' the recoil.
Your grip needs to be nothing more than firm (and consistent) the gun isn't going to jump out of your hands so no need for a stranglehold on it.
'Anticipating' the recoil is not uncommon and links in to having a firm and consistent grip. Even a slight 'anticipation leads to an involuntary, albeit small, change of grip. Remember - the gun sounds loud and impressive when fired but the recoil won't make it jump out of you hands.
