i have a blitz in .22 and a sortie in 17 and all the hatsan semi and auto actions are the same design and share parts etc so ... at this point its a love hate relationship lol ... focus on the blitz, its the closest to what your lookin at ... its not a competiton level accurate gun but decent enough, you cant do much with them as far as any mods because the system has to stay balanced to function, so .. it just is what it is .. the triggers are stiff, not match triggers im sure for liabiliy reasons but they can be worked and improved if you got basic mechanical understanding and skill .. parts are available, thats a plus, ive ordered some for the sortie .. so the guns are bulky, somewhat unwieldy, ugly, have a hohum fit and finish but .. and its a big but ... theres some serious horsepower there to fk sumpin up real good lol .. not kiddin .. you get after something with it its gonna 'feel the wrath' so to speak like not too many other airguns are gonna provide lol ...
...i will add that as far as i know, the rate of full power fire from a hatsan sa/auto action is unmatched by anything, no regs nothing holding it back .. fast as you can pull the trigger, you can hit something 8 times before it even knows whats going on lol ...
