I agree 3000 rounds is a lot of rounds for many people, depending on the particular top snap i could sometimes get more rounds, but I wouldnt bet very high on it.

I was using it, well 2 of them, as I alternated as they needed repairs, as my regular trap and sporting gun.

Have moved on to shooting Browning BSS's now. Not any more svelt then a 311, but handle a bit nicer for me, and way stronger. 23,000 rounds, was well used when I got it, and so far only trouble was a broken ejector trip, something I believe was a defect in that specific part, not the design.
