MR Longbeard I have a cz452 american and my trigger is adjustable,I have it set at 9.5 oz. and I didn't buy a trigger kit,there is an adjustment on mine from the factory and with the 4.5x14 nikon buckmaster on it you have just a ragged hole for a 5 shot group at 50 yards with cci mini-mags,my rifle loves them and remington sub-sonics.These gun are in a class by themselves for a $300 rifle you could spend $500to$600 for a used remington541T or more for a browning or kimber or several other high end 22's and have a more expensive rifle that doesn't shot any better.This is the only 22 that I have ever owned that would ever out shoot my 541T that I sold several years ago.The triggers are great and there is an easy adjustment by turning the trigger rod nut it is in the owners manual,I dont know if they offer a left hand version you could possibly order one,trust me these are incredible deals and very accurate.
