I bought a 13 round Para Ordinance .45 frame as kit back when the high capacity magazine ban was about to go into effect. It came with a recoil spring, spring guide, trigger (wider bow for the double column magazine), magazine release (for magazine width) and Series '80 style trigger group notch and a spacer plate so a Series '70 style trigger group could be used instead. I don't know your gun's configuration? If it is constructed with the Series '80 style trigger group, I expect you can use any Series '80 compatible slide and barrel. If constructed with a Series 70 style trigger group, you can use any Series '70 compatible slide and bow. Note that some gunsmithing could be required.
