i dont own a tikka so i dont know much about the durrability of the polymer trigger gaurd and magazine. what i can tell you is that these rifles are exceptionally accurate. if you didnt know tikka is owned by sako rifles, which is owned by beretta. the tikka's use the same barrels as the sako's, which means all of the tikka's have a match grade barrel. every single tikka rifle is test shot at the factory, and if the rifle doesnt shoot a 5 shot group under 1" at 100 yards, it doesnt leave. the real impressive part is that the ones that dont shoot under 1" dont get worked on, they just get melted down and recycled and they just build a new rifle.
