I had the same problem with my 24/7. I changed out the sights to Williams Fire sights instead of the Straight 8's but haven't had a chance to take it to the range for a try out yet.
I did read somewhere on this board that a shooter was having a similar problem that he resolved by not gripping the gun so tightly when shooting. He eased up on his grip, not enough to limp wrist it, and he said that it started shooting to point of aim. When I do get to the range I'll give it a try and see what happens.
Try some shoot and see targets and pay close attention to what your doing as far as input and hold. It took me a little while being new to hand guns but practice and attention to fundamentals goes a long way.
