I have a M3 and love it. I take it out to the skeet range and find it easier to swing with the target than other guns, but I was wondering the other day...... I know how to clear a jam using the pump in auto (Never had a jam though) but was wondering how, or if, the gun can be used solely as a pump (for pump competition). I thought this was possible with a M3. Is this option only available to clear jams like I know how to do in auto? Can it be used just a pump? Thanks.
