Hatsan ATP1

OK does anyone know anything about this monster? It’s a .177, fitted with a nondescript moderator and a 2x Poly Tech scope. Any info including approximate value would be appreciated. Thanks

I've got one, bought it direct from Hatsan USA as a refurb for right around $200. It is a beast, but' it's pretty accurate at 25 yards. It's heavy and much more accurate if it's resting on a table to take away most of the weight. Shooting it freehand can be a challenge! The trigger can be adjusted to where it's a hair trigger, not necessarily a good thing for a pistol. The power can also be adjusted, but it's a chore to do so. Mine is shooting the 7.9 gain Crosman Hollow Point at 850 FPS making a decent 13 FPE. I also picked up a second air cylinder, so I can hot swap them when shooting and then refill both before going another round. That definately extends the shooting time since I'm only getting a little over 2 mags per fill at that power level.
