Query: No marks = Nice gun

Two things are important in buying a quality air nailer. Does it have a two stage trigger, and how well dows it hold up? This gun has a two stage trigger that allows you to remove the nose of the gun prior to releaseing the hammer. The release of the hammer on woodwork is what creats the mark or dent in the wood. Theoretically you should be able to use this gun without a plastic nose portector and still not marr your wood. (I'll have to try it). And as far as durabillity... AccuSet, AccuSet, AccuSet!
