Hi
You have a Contender easy open frame. They are all called Contender until you get to the G2. There have been a lot of variations in Contender frames. The first ones had plain sides, the next had an eagle on one side, then a puma on both sides with engraving by the tail, then no engraving by the tail. Then you get the easy opening, easy to spot by the pin just above the trigger, then some with the puma head engraved on the sides. I left out stainless and AA ( I cannot spell Amorlloy), not to mention variations in hammers and grips, Nor all of the commemorative frames. But they were all Contender until the G2.
