NID # 500322 is a factory 28" gun with a unmarked Miller non selective trigger. I have shot this gun for a number of years, with out a hiccup ever. The ejectors and those big long cases still work as new. However another NID 32 " gun sports a .005 shim on the hinge pin. As per Bachelders Statement. I wonder if the long heavy barrels may have an effect on the hinge pin???
Mark When pattering old NID Ithaca 10, I still place A Salt Lake City Phone book in the middle of the pattern board in hopes of measuring pellet penetration, by counting the pages that the pellet traveled through...
