I have cleaned it very well. And it does cycle efficiently, just seems to catch a little. It appears the pump is contacting the reciever at just the right angle to drag a little. The forearm has just enough vertical movement when stroking to cause contact. Not really a huge deal, but can be distracting on doubles. Just not at smooth as most pump guns I've used int the past (primarily 870s). I have a student with a SNova that practically cycles itself, and it has the same vertical slop to the forearm. It is a backup to my M2. Just a little distracting when shooting clays yesterday.
