Well I have had tikka's now for a few years and never really noticed the polymer trigger guard , until a friend bought it up and I got the magnet out . The Mags were of some concern , but they proved the test of time , having shot more rounds than the average guy would in his life time
Since I am now an ol' fart, myself now and getting set in thinking I would never bought a rifle with "Plastic bottoms or triggers as with the TC venture rifles . Then too Ruger is using Polymer more and more and they prove the parts are strong.
Years ago We had a shot gun with a Plastic guard and it broke in the cold and a replacement part could never be found .
Well we have come a long way since the sixties,and Polymer hand guns too have proved themselves over the years , so Do Not Fear the polymer parts in firarms as Ruger is willing to put a truck on theirs to prove it stands up to the task, where as some of the alloy type metals could break in the cold .
Now Some of the tikka owners including myself reported that their guns shot more than a minute of angle when new though a lot of guys were very pleased with their guns from the start . Well I am happy to report too that After a hundred rounds or so the rifle does settle down and groups tend to tighten up.
Well then I find the rifles so smooth in the woods that I normally have a second round loaded as a reflex action before dropping the gun from the shoulder ,So why not get one yourself .
I know you will like it .
Happy
