I purchased mine from Bullseye North.
My observations is the trigger reset is longer than a MG2 or Pardini. It comes in a really nice lockable case, 3 mags, several barrel weights. Mine works well with RWS. SK and Aguila std velocity. CCI std is acceptable, with a malfunction (stove pipe) one in every 150-200rrs. However CCI doesn’t seem to be what it used to be.
In comparison to my MG2 my sport pistol scores are nearly identical but I have more good “deep” tens with the 6007. Maybe they have make an updated 603.
For the price this is an excellent value and ideal for 25m (sport pistol).
What I don’t like is there is no exploded diagram in the manual and currently spare parts are limited (on order).
Hope this helps
