The Gamo PT-90 is a very
replica of the H&K USP. It fits the hand well, but has a very
heavy DA and SA action (even the SA action is nearly 10 lb).
This makes it difficult to shoot groups as tight as the PT-80
will produce even though the two guns use the same valving and
barrel. Gamo discontinued importation of the PT-90 in 2006 after only
four years of production. Gamo added the PT-90 back into their
imported product mix in late 2007 and then dropped it again in
late 2008 or early 2009. The PT-90 remains available in Europe
but is no longer imported to the USA.
