I agree with John, you don't want a tight group oh a bad guy, you want to spread the shots out, with more chances of hitting vital organs.
If I thought I was having a problem with my shooting technique, I would have an experienced pistolero watch me, and see if he could see what I was doing wrong.
The range masters at the indoor ranges I go to are always happy to spend a few minutes with you and let you know what they think is going on.
