i did a lot of research before i added the wilson mag extension to my 870. i'vee been happy with it so far but have some questions about reliability or lack there of.
it seems that most people are of the thought that a standard mag tube is more reliable. why?? the extension is essentially just the same design only longer. is it because of the added pressure on the first round inserted due to a higher powered spring being compressed?? i remember hearing of a shell's crimp being split and the round jamming in the tube at gunsite, but IIRC, that was due to a defective metal follower.
i can understand the school of thought that it could be bent or dented and cause problems. honestly, the wilson extension is built pretty darn tuff and the sling mount design is what sets them apart from the others IMO. the mount sits ahead of the threads and is comformed snugly to the bbl. its seems to me that if it were dropped on the mag tube, the sling mount would prevent major stress from being applied to the threads, which seems to be the weakest point. now if something slipped over the end of the tube and pulled down away from the bbl, there might be a problem. i guess that is where the bbl clamp comes in, along with reducing vibration.
sorry to bring this up again, but i'm interested in first hand accounts of a mag extension malfuntioning, and the cause behind such.
any comments or opinions are welcome
