I've been shoot 1911's for most of my life, so imagine my supprise when I shot my first 100 rds out of my sid P2022, aiming at center mass on the target my hits were all over the target. Any insight into the manual of arms for a SA/DA pistol?

Practice, is all that I can say. Prepping the DA trigger during presentation is a must to decrease time; however, it takes time and of course, a lot of practice.

Going from a SAO platform to a DA/SA - goes back to basics. You are all over the place indicates trigger control.

The extra effort you are putting into that DA pull of 9-15 pounds versus the 4-5 pounds of a typical 1911. It's also a new gun so even in SA you need to practice the trigger control. You are most likely having trouble adjusting to the DA pull and different recoil.

Like the post above - you have to practice and practice to overcome. Go back to basics.

It's a strange thing but you may have to bench shoot this gun until you come to believe that it can shoot. What I mean is that when people shoot another gun - when it's not hitting the target like it "should" most will think it's the gun's fault. You might just have to bench shoot it to convience yourself and then work on your "issues" (e.g. grip, trigger control, and/or recoil... meaning flinching).

Have fun and practice.

My suggestion woud be an exercise called the wall drill. Unload the gun and double check it to be sure. Go to a safe place for dry fire practice. Put the muzzle about 1 inch from the wall. Focus on the front sight and practice pulling the trigger. You do not want the front sight to move during the entire exercise. Do this for approximately 15 minutes a day and see if thar does not improve your hit ratio and tighten the groups up considerably. This will help with any action type including your SA 1911's
