This is a "fast action" trigger...from the review:
The Fast Action mechanism on the new MR Eagles is something else entirely. For one thing, it is striker fired; all other pistols called Fast Action are hammer fired. For another, more important thing, when the MR Eagles are decocked they revert to a true long-pull firm double-action first-shot trigger, with subsequent shots firing in short-pull single-action mode exactly as any conventional double-action/single-action auto pistol. Fast Action applies only if the striker is not decocked after an initial round is manually chambered prior to the first shot. And the MR Eagles have full double-action repeat-strike capability in case of a first-strike light primer indent.
When you cycle the slide and chamber a round on the MR Eagle, the striker is cocked, but the trigger remains in the full forward “double-action” position. Pulling the trigger at that juncture requires only a very light pressure of about 4 ounces to move it back approximately 0.85 inch to the “single-action” position, where an additional 1/8 inch, 4.5-pound stacking stroke will fire the gun. If you release the trigger without firing after the initial 4-ounce part of this “two-stage” takeup, it will remain in the rearward single-action position. For all subsequent shots after firing, the trigger returns to the 4.5-pound single-action position
