An auto loading gun remains locked up until gas farther down the barrel cycles the bolt and the projectile(s) are within a couple of inches of exiting the barrel. The 1300 bolt headunlocks before the hammer ever gets to strike the firing pin. If you are not holding on to the forearm the bolt begins opening up and moving rearward before the slug even gets out of the shotgun shell.
Hanging a bag of shot on the barrelsure as heck isn't helping you accuracy either.
.............gunsmith or shop who probably will slap it on in a half-ass-ed fashion
I am glad you speak so highly of us gunsmiths there Steve863 considering you don't even know how a semi auto seems to work.
