Hey guys, I have a Mossberg 835 grandslam model I bought in 2011, and every so often i get a light primer strike. If i rechamber the round with the light strike, it fires on the next trigger pull. I noticed also on every shot, the firing pin strikes the primer off center no matter what brand of ammo. Anyone else have this problem? Also to note, I have an older late 1990's 835 which strikes the primer dead center. QC issue? Anyone else notice any similarities with the newer guns?
