longrifle, I haven't heard of any actual complaints that the Tikka magazines fail, therefor I assume the "plastic" used is good enough.
I never questioned that.
Just another thought, what if you could get a metal magazine, would that in itself assure it would bebetter than the plastic?
Of course a durable polymer would be better than brand A pot metal. But again, I never said anything about that.
What I said was, you cannot compare the polymer in a magazine to the polymer in a Glock. It is apples to oranges. The are not the same.
