Hey guys and gals new 930 tactical owner with 4 shot mag tube and 18 inch breacher barrel, does not have a heat sheild. My question is I am installing the 2 shot nordic components extension tube, can I get the nordic comp.clamp to fit this, is there enough room left? Can someone please measure their clamp width and tell me how wide it is and also maybe the measurements of a heavy barrel and the regular barrel? Mine is brand new if that helps and thanks very much anybody!
