I've noticed after a couple of range trips with my new 26, that it has the tendency to eject shells sometimes and peg my forehead. It happens every couple of mags or so. Most of the shells eject correctly to the right, but every so often I'll have some land on my right sleeve, or come straight back and either land on top of my head, or peg my forehead straight on. I haven't really noticed this with my 19. Anyone have any ideas on what could be causing this?
