If you can afford (and can find) any CCI Mini-Mags, you'll find your groups will tighten up even more, especially noticeable at the longer distances. Just keep practicing good shooting techniques, including proper grip and trigger control and you'll eventually be able to rapid fire tight groups consistently. Wrap around the grip, thumbs forward, with support hand thumb way out there, on the frame. This helps control side movement, if you do slap the trigger when shooting fast. Dry fire, without even racking the slide; just keep saying squeeze, squeeze, squeeze, while you pull the trigger, with the front pad of your index finger. Eventually, all of these things will be muscle memory and you'll do them automatically. You'll wonder how you ever shot a gun the old way. I train all my "students" with this method and it's worked every time.
