Grip moving

[pokerlife]

Is it normal for the butt end of the club to move around a little when your getting to parallel ?
When the weight of the clubhead sets at the top it kinda moves the butt end of the club out from under my heal pad.
If this is not normal what should i do just grip the club tighter? Even when trying tighter grip i still feel it wiggling around a little

Interesting - I have noticed the same thing. Looking forward to hearing some answers on this.

Slippery grip surface as in grip more than 6 months old. Grip too small for you.
