Some elementary points to check:
1) Take a very close look at the muzzle. Preferably with a watchmaker's eyeglass. Are there any signs of damage, nicks in the crown etc? Touching up a crown is a simple 5-minute job for any gunsmith.
2) Are the system screws properly tightened up?
3) Is the barrel binding in the channel at any point?
