Angry Gun power up silencer for unicorn ag 1911

In good condition, tried it with my 1911`s with a screw on silencer adapter but

the slide wouldn`t cycle.  I cut down the spring inside the silencer a little so it

had less tension and the slide will cycle but is still very sluggish and sticks randomly.

It may work better with the specfic unicorn or ag 1911 it is suggested for or with a different

silencer adapter but i don`t know.
