I used to be all ove the place with my XD; one day the front site came lose;
took it to the range, and the gunsmith said he'd put it back at no charge. since then, it's dead on balls accurate. I'm not sure what he did, but I ove it. I wonder if the sites are off on your PT1911.
speaking of which...that's the 1911 I'm eyeing; let me know how you like it.
