I have observed the same condition on single barrel trap guns. Since they are a lot easier to diagnose I offer the following. The sear of the SBT gun with this problem is about 20 thousands shorter than the sear without the problem. Taking the stock off each gun and oberving the sear hammer assembly when cocking the gun it is apparent that when you depress the barrel to clear a shell the sear just rides up the back of the hammer behind the notch. Just what we would expect. With the short sear the hammer does not fully retract; the hammer in the none-fully-retracted position transfers a non-fully-cocked condition back through the cocking lever. That's why when you push the barrels down to free the shells you feel spring tension, you are pushing against the hammer spring. I don't know if my theory is 100% but I am confident of the problem in single barrels. Also I don't know if they were shipped that way or through the years the sears wore down causing the condition. In trap guns I suspect that amateur gunsmiths were trying to achieve better trigger pulls through sear/hammer notch work which shortened the sear.
