My Frasers pretty much feel the same when cycling either from fired or unfired.
The only spring back from open is just from the extractor rebound.
The block can be completely lowered under very little or no resistance and then the extractor is loaded which, of course, is where the resistance from extraction is felt.
Mine both have the rotating lever latch, one oval, and one with the thumb lever extension. These latch the lever, keeping the block up and the action closed.
