It’s anticipation, unless your sights are waaay off. 2" off at 7 yards is significant, and would probably require a lot more than 2 clicks of adjustment to bring to center anyway.
I don’t necessarily think that it is trigger control on its own that is the issue, as one can molest the trigger of most guns pretty badly (especially a 1911) and still shoot fairly well… as long as grip is good and the shooter does not move anything other than the trigger finger as the weapon fires. Working trigger control helps the shooter avoid anticipation, which is why the skills tend to develop in unison.
Focusing on smooth, gradual increase of pressure on the trigger so that the trigger is moving directly to the rear with pressure on the face of the trigger alone as the shot is fired will reduce the occurence of pre-ignition push on the gun with the firing hand, or the other plethora of anticipation manifestation. To be frank, it really doesn’t matter what type of anticipation is affecting your shooting, working through anticipation is the most important path to go down.
I like to work out anticipation on the initial shot/precision shots first and then move onto multiple shot anticipation issues.
There are a lot of ways to do it, so what I recommend is simply my recommendation to someone that I am not working directly with:
Dedicated trigger control dry-fire work. Most benefit comes from one-handed dry-fire. Start of slow, taking about 5 seconds to break the shot. Those 5 seconds are dedicated to pressing the trigger with smooth, gradually increasing pressure. Pay attention to front sight movement as the hammer falls. Optimally, there should be no movement of the front sight. Gradually reduce the time that you are permitting for trigger travel, but ensuring that there is no front sight movement as the hammer falls. Once confident, balance a dime on the front sight and work on breaking the dry shot without the dime falling off the front sight.
Ball and dummy drill. Randomly insert dummy rounds into each magazine of live rounds. Do this with as many magazines as you can, trying to keep each one random (not predictable). Throw the magazines into a bag. At the range, pull a random mag out of the bag, and without looking at the magazine (to avoid knowing where the dummy rounds are in the stack) insert into mag well and make ready. Proceed to shoot slow-fire, precision shots. Pay attention to the front sight to see what happens when you hit a dummy. If you see/feel the gun/sights do anything other than stay perfectly on target when the hammer falls there is something wrong (anticipation).
Dry/Live drill. Requires a partner.
Have a partner take your gun and randomly hand you back a loaded/unloaded gun. For each shot, focus on precision shooting. Just like the Ball and Dummy, pay attention to what happens when the shot is dry. On any occasion that the sights/gun move during the unexpected dry shot, immediately remediate with 5 dryfire shots. If the shot is live, immediately attempt to fire another shot. Again, if the sights/gun move on the dry second shot remediate with 5 dry shots.
2 shot dry/live.
Either do a 50/50 mix of live and dummy rounds or chamber a round and then remove the magazine.
Fire a live shot and then immediately follow with a dry shot.
Same as before, watch for sight movement on the dry shot.
Self Paced live/dry
Dryfire 5x for every live shot. Focus on maintaining the exact same trigger press for both the live and dry shots. It is very common for shooters to press the trigger more smoothly and gradually when they know it is a dry shot then when they know it is a live shot. Rushing the trigger just before the shot breaks instead of maintaining gradual pressure (regardless of speed) leads to anticipation since the shooter is trying to fire the shot “NOW!!”.
I like to do this for at least 15 shots when I am getting back into the groove of precision pistol shooting.
Berm Shooting
Aim into a nondescript portion of the berm, looking over the sights, focusing on the berm. Starting out slow (about 1 second between shots) work on a smoothly pressed 5 shot string. We are ignoring the sights in order to work out the desire to make the shot happen “NOW!!” in relation to sight alignment/picture. Gradually increase pace until you are working at the “trigger finger cyclic” rate. Revisit the other drills to ensure that you are not just mashing the trigger.
These are a decent starting point.
ETA: just saw that Surf posted before I got this off. If it’s the video I think it is, it is a very good technical discussion on trigger control and how it pertains to different pistols.
