Hello jrock and welcome to the forum.
Field stripping the HSc results in 5 sub-assemblies or parts: Frame; Slide; Barrel; Recoil Spring; and Magazine.
1. Remove the Magazine, lock open the Slide, and check the chamber clear.
2. Reinsert and remove the Magazine to close the Slide.
3. Leave the Hammer cocked and put the manual Safety ON (S visible).
4. Depress the Barrel Latch inside front of the Trigger Guard.
5. Move the Slide forward and up to clear the Frame.
6. Invert the Slide and push the Barrel at the chamber forward.
7. When the Barrel breech just clears the bolt face, tilt it up and out along with the Recoil Spring.
