Just in case anyone is interested. My local gun shop guys talked me out of doing any mods because this is such a rare gun with the H & K parts and the Benelli parts and the "tactical pump/semi" aspects of the gun.
I'm planning to sell my M1 Super 90 that has the H & K markings on the receiver and the Benelli markings on the barrel. Bought in 2001 and only shot at the range once.
