How to Increase Accuracy with a Glock?

Hi, I purchased a glock a few weeks ago and have been to the range about 3-4 times since. When i first bought it, I couldn't hit the broad side of a barn at 10 yards+, a few trips to the range later, Im getting grouping of about 10 inches at 10 yards. It's not terrible in my opinion but no sharpshooter status. Do you have any tips or tricks I could apply that could increase my accuracy? Thanks
