There is a lot of value in doing this repeatedly. Bring the gun into a compressed high ready with the trigger/hammer in DA. As you press forward, take up some of the slack in that long heavy trigger pull. This helps minimize the amount of trigger you have to pull once the gun is fully extended. Do this, break the shot, then decock and do it again. And again. For a 12 lb trigger if you can take 6-8 lbs up before the gun hits your full extension, it'll minimize any anticipation/gun movement. (It won't make it entirely go away, but it helps mitigate the issue.) You can shoot a DA/SA system as well as you can a striker, but it requires more work. When my department issued me a DA/SA gun I had to do a metric TON of dry fire and additional supporting live fire work to get comfortable with it.
