so far no problems, i just dont like how they changed the hammer action.
my older wolf if you hold the trigger and the firing pin will stay out until the trigger is let go.
the newer hammer action is a soft spring load that springs the firing pin back.
it works fine, i just like the older style better.
they also changed the sights from the cheap plastic ones to a better metal sight.
oh... and it is much lighter than the black one.
well worth the $227 that i payed for it at wally world.
