Shot PPC for many years and I think shooting "weak" hand made me a better shooter. In a 150 round match 24 rounds are "weak" hand. When you learn to shoot with your off hand you should carefully analyze your strong hand grip and stance and simply reverse it. Some days my off hand hits were better than strong hand because I worked a bit harder on them. As the captain pointed out sometimes the gun needs to be in the other hand.
Got a little tired of shooting standard load .45's in my little lightweight carry gun a few weeks back, simply switched hands and hits improved. Shooting buddy had never seen that trick before, he was impressed.
