I just bought the standard Condor O/U in 28" for waterfowl. Got a good deal, $299 at our local Dick's. Anyways, I have been preparing for the upcoming goose season by shooting some trap and noticed that after a few shots the fore end is becoming loose. It has even fallen off once during a round of trap! Yesterday I noticed that after a few shots the release lever seems to be opening up, if I squeeze the fore end to the barrel it tightens back up for the next few shots, but then I have to squeeze it tight again a few minutes later. I have taken it all apart and cleaned it very well. Everything seems to be fine including the release spring and latch on the barrel that the forearm attachs to. I am thinking that the frequest open during trap may be causing this loosening of the fore end. I am shooting the gun well but this is not acceptable, any one have any input on how to correct this :?
