I have 2 XD9's SC & 4" and a Sig Mosquito.Recently (2mos.) purchased a new Sig 229 SAS 40cal. for my consealed carry. I have put over 1000 rounds through both pistols and I am able to keep all rounds from the XD9's within 4" or less, using Win. 115gr. target ammo. But with the Sig (also using Win. 165gr. target ammo) my rounds are scattered, low and to the left (approx 4 - 6" from my aiming point). I am still getting used to the Sig DAK trigger sytem, and I have tried to alter my grip and reset the rear sight (which moved the rounds under my sight point). With Sig's reputation for accuracy right out of the box, I am a little disappointed in my results. In some of the threads I remember reading about accuracy improvements with match grade barrels like Barsto. I have not had anyone else fire it yet, but that's next! I am considering giving it to a gunsmith to check it out, but I still think it's something I am doing wrong. Any suggestions?
