10. The archery release device of claim 8 , wherein the release body defines a guide surface configured to guide the first compression spring along an axis and wherein the guide surface is configured to prevent an introduction of a bending moment into the first compression spring upon actuation of the first and second jaws.

11. The archery release device of claim 10 , wherein the guide surface includes a pair of guide slots formed through a side wall of the release body, wherein the release body includes a bore for receiving a piston configured to retain a roller sear at one end thereof for engaging a surface of the trigger, and wherein the roller sear includes an axle having ends which engage and are guided by the guide slots of the release body.

12. The archery release device of claim 10 , wherein the guide surface includes a pair of guide slots formed through a side wall of the release body, the guide slots configured to guide a roller sear biased against the trigger by the first compression spring.

13. The archery release device of claim 8 , wherein the second compression spring produces a spring bias force which opposes a first spring bias force produced by the first compression spring.

14. An archery release device comprising:

a release body configured to be coupled to a harness;

a first jaw pivotally coupled to the release body, the first jaw comprising a first jaw portion and a first interface portion;

a second jaw pivotally coupled to the release body, the second jaw comprising a second jaw portion and a second interface portion; and
