Bill, I axed those links. Don't know why, but could not post from Photobucket. Seems to happen every now and then on this forum, and not just to me. The box was not checked.
Metal triggers aren't the be-all, end-all and certainly don't denote quality. As mentioned, look at the low end Chinese guns with their stamped triggers. Stamped steel triggers were predecessors to plastic ones, anyway. As long as it works, what difference does it make? I would rather have a decent plastic trigger than a crappy metal one, any day. And, if the look or feel is a concern, get a trigger shoe like the ones for paintball guns. Come in a variety of colors, too, to suit your tastes.
I just wonder why everything about these triggers has to be addressed in emails? Are they THAT expensive?
