I own and prefer the Shockwave over the standard Remington Tac-14 however I like the wooden stocked version of the Tac-14 more than the Shockwave. This new Tac-13 I like best of all!

Being a semi-auto it might be a lot softer shooting than the pumps which I don't find objectionable but this should be better.
