the 590 i keep for HD is one with plastic trigger group and i cannot think of anything i could do to it to tear it up..The only reason the steel one exists is because uncle sam specified it for military--my gun or the one i had before this one ever had any malfunctions--i for one would not loose one minutes sleep over the trigger guard being plastic. By the way my glocks are plastic. By the way H&K's are plastic...Dick
