If a right handed shooter jerks the trigger... it will cause his firearm to shoot to the Right... not the Left....try doing some dry firing with snap caps & watch where your muzzle goes when you jerk the trigger... I suspect that the OP is jerking it harder than he thinks he does... just my opinion based on what I've seen in the past... if you have a set of Crimson Trace grips or another brand of laser on your handgun... dry firing the pistol will will bear me out.....just bring up the gun, pull the trigger as you normally do ,see where the the red dot.
