For combat hits, the BG is no longer a threat.
But you do seem to be hitting a bit low and left. You may be anticipating the shot and pushing the gun just before the shot, causing it to go low. Hits on the left (assuming you are right handed) are usually caused by not squeezing it straight back.
Take a look at these drills, in particular the Dummy Round Drill. I did this one and it pointed out my flinch. Link Removed There's a lot of good drills here.
I'd also try to do some shooting competitions. The combination of timing your shooting and shooting in unfamiliar scenarios helps your overall shooting. USPSA and IDPA are two national groups. I shoot with a more informal group and it's always fun and you can get tips on your shooting. Watch it though - it can get intimidating when some of these people show up with tricked out guns with scopes and trigger jobs, etc. It can get expensive quickly. In these competitions you can do things that many ranges prohibit - drawing from holster, double taps and quick shooting, etc.
