I bear part of the guilt in all this un-popularity of the plastic trigger groups
since I started a thread about them some time ago.

The reason was that a lot of people (including myself)
were pissed-off at that time because Ruger
did not announce it in any way (officially or not)
they just switched to plastic like there was nothing changed,
and the general feeling was that they tried to bring it in
through the back door like a cheap prostitute.
It was nice if they made public some tests, trials, numbers,
prior to just switching to plastic, but they didn't.
Right now, the plastic TG's have enough number of shots in the field,
and it's safe to say that they stand their ground and
they perform at the same level with the aluminum ones.
